The Mullard 10M Series! Designed and built specifically for audiophiles with industrial-grade specs by the special high-end audio unit at both Blackburn and Mitcham factories (recall Philips' SQ but this is at a much higher caliber.) These tubes went through rigorous testing \u0026amp; screening processes according to the highest standards of the tube industry. Minimum 10K hours of heater life, matching triodes and near zero noise are just the beginning. The 10M Series was Mullard's official answer to the super high-end Telefunken E88CC tubes (CV2493, E188CC and CCa) and remains one of the very top choices for serious audiophiles and sound professionals. The only one problem (and there's no real solution to it) with these tubes is they are elusively rare as they were produced in very limited quantity and only in select years of production. Exclusively presented here by Soundlumia is a perfect matched pair of 10M Series from the 1960 Blackburn production. Welcome to the concert hall of 10M Series!\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan size=\"4\" face=\"Arial\" style=\"font-family: Arial; font-size: large;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan size=\"4\" face=\"Arial\" style=\"font-family: Arial; font-size: large;\"\u003eFor those who feel the Mullard E88CC tubes are less analytical than their German counterparts, the 10M Series proves that the best tube can be both analytical and musical. One can almost say this is a better version of Telefunken CCa because you get the laser precision in detail retrieval of Telefunken tubes and the unmistakable British warmth in sound, which is NEVER found on Telefunken. Next, the holographic soundstage...another Telefunken \"proprietary\" feature is being seriously challenged here as well: 10M Series' presents a less curvy sound stage than Telefunken CCa without compromising the full 3D imaging. You hear everything right here like at a concert hall INSTANTLY and don't have to look for the harp sound in the corner (recall how many times you have done this with Telefunken tubes?) Now there's only one last thing needed to treat the Telefunken \"thinness and hollowness\". How about some expansive and forward midrange? But isn't that what Mullard does the best after all? It only gets better on the 10M Series: elegant,  gentle, calm, smooth and fluid.  \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan size=\"4\" face=\"Arial\" style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan size=\"4\" face=\"Arial\" style=\"font-family: Arial; font-size: large;\"\u003eAny sound review on a Mullard tube without discussion of its \"British warmth\" would be incomplete. So we have dedicated a full paragraph to the comparison between the classic Mullard warmth and the 10M Series warmth. Recall how many times you feel the vocals on Mullard's get too warm it feels like heat right in your face? That is gone on 10M Series! The moment you turn on your music, the 10M warmth begins to release slowly (and of course surely) and gently flows through your ears, your veins, your bones and reaches your fingertips before you know it...and then it warms your heart. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan size=\"4\" face=\"Arial\" style=\"font-family: Arial;

pleasant to listen to: liquid, euphonic, with a slightly warmer midrange than many other German tubes, which makes your sound experience smooth and non-fatiguing, and all that happens on a unbelievably realistic holographic sound stage, where everything feels bigger, wider and taller. Sound texture can be felt through infinite levels of details, laying on top of each other, both in depth and in width. So your quest for superb sound clarity can end right here.

The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens E88CC tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken E88CC tubes, Siemens E88CC's produce a warmer, smoother and more musical sound. To see how they compare to each other, please also see Soundlumia's exclusive Telefunken E88CC listings.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cb\u003e\u003cspan style=\"font-family: Arial;

This special sound characteristic can only be found on Valvo Hamburg tubes. And because of the added substance in sound, the overall tonality of these tubes feels sweet, warm and musical, and the ambient clues sound closer to your ears.

Bass is incredibly deep but well controlled and feels as accurate as on the high end German ECC82's (Siemens, Telefunken, Valvo etc.)  We would recommend these as an excellent alternative if you are seeking the high end Holland ECC82 tubes that can deliver the legendary Philips house sound flawlessly. \u003c\/span\u003e\u003ca\u003e\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"color: rgb(0, 0, 0);

Every piece of music you play through these tubes sounds like from a vinyl record, whether your sound source is phono or not. The sound stage is spacious, deep and structured. Bass is incredibly deep but well controlled and feels as accurate as on the high end German ECC82's (Siemens, Telefunken, Valvo etc.)  We would recommend these as an excellent alternative if you are seeking the high end Holland ECC82 tubes that can deliver the legendary Philips house sound flawlessly. \u003c\/span\u003e\u003ca\u003e\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"color: rgb(0, 0, 0);

Every piece of music you play through these tubes sounds like from a vinyl record, whether your sound source is phono or not. The sound stage is spacious, deep and structured. Bass is incredibly deep but well controlled and feels as accurate as on the high end German ECC82's (Siemens, Telefunken, Valvo etc.)  We would recommend these as an excellent alternative if you are seeking the high end Holland ECC82 tubes that can deliver the legendary Philips house sound flawlessly.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: rgb(0, 0, 0);

They are as sweet and smooth as the Amperex Holland PQ tubes, with even better detail and very spacious sound stage, which offers an amazing bird's eye view of the shape of your sound, so you know exactly how tall and wide the sound stage is. The tone is warm yet lively, mids are forward but also expansive like what you hear on their cousins from the Holland factory, bass is punchy but not heavy. We have recommended them to so many satisfied customers that we have given them a nick name \"sound purifier\" - the sound that comes from these tubes has absolutely no edginess, glassiness or harshness, and you hear nothing but the soul of your music and all of it. They are the best tubes to to put in the phono stage to \"purify\" your sound in my opinion. As to vocals, I have no further comment than that the best Mullards were actually sourced from Holland PQ's (Made in Gt. Britain w\/ Heerlen date codes) and USA PQ's beat the Holland ones in vocals period. Listening to Righteous Brothers' Unchained Melody through these PQ tubes should be on your bucket list, no matter what type of music you enjoy.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv\u003e\n\u003ch2 class=\"MsoNormal\"\u003e\n\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003eAmperex PQ 6922 = E88CC D-Getter Matched Pair - New York, USA '60 - Near NOS\u003c\/span\u003e\u003c\/strong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003e\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003ch2\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003e$ 504.00  \u003cem\u003e#SOLD#\u003c\/em\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cimg\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0809\/2388\/5888\/files\/1741264731063.png?v=1741264793\"\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003ch1 class=\"Polaris-Header-Title\" tabindex=\"-1\"\u003e\n\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h1\u003e\n\u003ch2 class=\"MsoNormal\"\u003e\n\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003e1× Amperex PQ 6922 E88CC \u003c\/span\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003eWhite Print \u003c\/span\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003eD-Getter - Hicksville, NY, USA '59 - NOS -\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003ch2\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003e$ 247.50\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0809\/2388\/5888\/files\/1741265457657.png?v=1741265489\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Amperex","offers":[{"title":"Matched Pair \/ New York '60 PQ - Near NOS","offer_id":50364221096256,"sku":"266917988655","price":504.0,"currency_code":"USD","in_stock":false},{"title":"Single Tube \/ New York '59 PQ White Print - NOS","offer_id":50364275163456,"sku":"","price":247.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/2388\/5888\/files\/57_7bf74f5c-daa4-464d-a081-7a3e43c767b6.jpg?v=1721716097"},{"product_id":"2x-mullard-12au7-ecc82-short-plates-gold-pin-10m-master-series-blackburn-61-copy","title":"1x Mullard ECC82 12AU7 Short Plates 10M Master Series - Blackburn 1960s Gf1","description":"\u003cdiv\u003e\n\u003cb\u003e\u003cspan style=\"color: #2a633a; font-family: Arial; font-size: large;\" data-mce-style=\"color: #2a633a; font-family: Arial; font-size: large;\"\u003eSoundlumia's Opinion\u003c\/span\u003e\u003c\/b\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003eNo other tubes can deliver vocals like the British made Mullard's...that's a fact. And no British made Mullard's can deliver vocals like the 10M Master Series...this is the end game! Born with gold pins (recall Telefunken ECC802S and Siemens E82CC - even the 3-mica version do NOT have gold pins), these ECC82 tubes were specifically made for audiophiles by the special production unit at both Blackburn and Mitcham factories. They had gone through rigorous testing \u0026amp; screening processes according to the highest standards of the industry at the time of production. Minimum 10K hours of heater life, super rugged industrial build, section-to-section match and near zero noise are just the beginning. The 10M Master Series was Mullard's official answer to Telefunken's ECC802S and remains one the very top choices for serious audiophiles and sound professionals. The only problem with these tubes is they are elusively rare as they were produced in very limited quantity and only in select years of production. Welcome to the concert hall of 10M Master Series!\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003eFor those who feel the Mullard ECC82 tubes are less analytical than their German counterparts, the 10M Master Series proves that the best tube can be both analytical and musical. One can almost say this is a better version of ECC802S because you get the laser precision in detail retrieval of Telefunken tubes and the unmistakable British warmth in sound, which is NEVER found on Telefunken. Next, the holographic soundstage...another Telefunken \"proprietary\" feature is being seriously challenged here as well: 10M presents a less curvy sound stage than ECC802S without compromising the full 3D imaging. You hear everything right here like at a concert hall INSTANTLY and don't have to look for the harp sound in the corner (recall how many times you had to do this with Telefunken tubes?) Now there's only one last thing that's need to treat the Telefunken \"thinness and hollowness\" problem. How about some expansive and forward midrange? But isn't that what Mullard always does the best? It only gets better on the 10M Series: elegant, smooth, gentle, subtle and fluid.  \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003eAny sound review on a Mullard tube without discussion of its \"British warmth\" wouldn't be complete. So we dedicated a full paragraph to the comparison between the classic Mullard warmth and the 10M's warmth. Recall how many times you feel the vocals on Mullard's get too warm it feels like heat right in your face? That is gone on 10M! The moment you turn on your music, the 10M warmth begins to release slowly (and of course surely) and gently through your ears and reaches your fingertips before you know it...and then it warms your heart. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e10M Master Series = the ultimate audiophile tube.\u003c\/span\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cb style=\"color: rgb(42, 99, 58);\" data-mce-style=\"color: rgb(42, 99, 58);\"\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003eProfessional Tube Testing \u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb style=\"color: rgb(42, 99, 58);\" data-mce-style=\"color: rgb(42, 99, 58);\"\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003eThis tube was tested and certified by \u003cb\u003eRoeTest V11 Professional Tube Testing System\u003c\/b\u003e with the following result: \u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\" data-mce-style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\" data-mce-style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eTube 1:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\" data-mce-style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eMeasured transconductance(GM): 1.51\/1.48 mA\/V\u003cspan style=\"mso-spacerun: yes;\" data-mce-style=\"mso-spacerun: yes;\"\u003e  \u003c\/span\u003e- 69%\/67% (100% = 2.20 mA\/V)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\" data-mce-style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eMeasured plate current(IA): 7.435\/7.705 mA\u003cspan style=\"mso-spacerun: yes;\" data-mce-style=\"mso-spacerun: yes;\"\u003e  \u003c\/span\u003e- 71%\/73% (100% = 10.5 mA)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\" data-mce-style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eNO shorts, leakage or gas.

And no British made Mullard's can deliver vocals like the 10M Master Series...this is the end game! Born with gold pins, these ECC83 tubes were specifically made for audiophiles by the special production unit at both Blackburn and Mitcham factories. They had gone through rigorous testing \u0026amp; screening processes according to the highest standards of the industry at the time of production. Minimum 10K hours of heater life, super rugged industrial build, section-to-section match and near zero noise are just the beginning. The 10M Master Series Mullard's official participant of the ultra high-end ECC83 competition and remains one the very top choices for serious audiophiles and sound professionals. The only problem with these tubes is they are elusively rare as they were produced in very limited quantity and only in select years of production. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eFor those who find Mullard ECC83 tubes are less analytical than their German counterparts, the 10M Master Series proves that the best tube can be both musical and analytical. One can almost say this is a better version of Telefunken ECC83 because you get the laser precision in detail retrieval of Telefunken tubes and the unmistakable British warmth in sound, which is NEVER found on Telefunken. Next, the holographic soundstage...another Telefunken \"proprietary\" feature is being seriously challenged here: 10M presents a less curvy sound stage than Telefunken ECC83 without compromising the full 3D imaging. You hear everything right here like at a concert hall instantly and don't have to look for the harp sound in the corner (recall how many times you had to do this with Telefunken tubes?) Now there's only one last thing that's need to treat the Telefunken \"thinness and hollowness\" problem. How about some expansive and forward midrange? But isn't that what Mullard always does the best? It only gets better on the 10M's: elegant, smooth, gentle, subtle and fluid.  \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eAny sound review on a Mullard tube without discussion of its \"British warmth\" is not complete. So we dedicated a full paragraph to the comparison between the classic Mullard warmth and the 10M's warmth. Recall how many times you feel the vocals on Mullard's get too warm it feels like heat right in your face? That is gone on 10M.

While as quiet and analytical as the best Telefunken E88CC tubes, Siemens E88CC's produce a warmer, smoother and more musical sound. To see how they compare to each other, please also see Soundlumia's exclusive Telefunken E88CC listings.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003ch4 class=\"MsoNormal\"\u003e\n\u003cspan style=\"font-family: Arial;

Yet we picky audiophiles approve of their superior qualities...on all accounts: matched triode, low noise screening, minimum 10,000-hour heater life expectancy, carefully controlled frame grid winding and anti-vibration build - this is about as good as it can ever get in the entire vintage tube world! \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eAs a major step-up of Siemens E88CC, the CCa tube naturally posses all the greatest traits of the family: the airy and transparent natural tone unrivaled even to this day, the extended yet never tizzy top end, the incisive, neutral and balanced midrange presentation, the clearly defined and deeply controlled bass that's always there with the perfect amount of weight. All these fantastic sound characteristics multiplied by three and that's what you should expect from the Siemens CCa.  And the most defining sound characteristic of Siemens tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to reveal the subtle ambient clues that help complete building a true 3D holographic sound reproduction. The sound stage of Siemens CCa is amazingly wide and feels like the holographic field gets \"flattened\" into a panoramic view of your music, still curvy and enveloping, and with added head room - nothing in the sound can escapes your ears (or eyes.) While as quiet and analytical as the Telefunken CCa\/E88CC tubes, Siemens CCa also creates a warmer, smoother and sweeter German tone (and very German) that's rarely heard elsewhere.\u003c\/span\u003e\u003cspan style=\"font-size: 13.0pt;

Every piece of music you play through these tubes sounds like from a vinyl record, whether your sound source is phono or not. The sound stage is spacious, deep and structured. Bass is incredibly deep but well controlled and feels as accurate as on the high end German ECC83's (Siemens, Telefunken, Valvo etc.) We would recommend these as an excellent choice if you are seeking the high end ECC83 tubes that can deliver the legendary Philips house sound flawlessly. Thanks to the super rare foil d-getter on this pair, you get with fast response (as in the solid-state fast), overwhelming detail in sound and the realistic bass - this is truly the Holy Grail sound of Philips ECC83 that one should not miss!\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial;

the sound stage is expanded in all three dimensions - wider, taller and deeper, and almost feels like projected from a 45-degree angle somewhere (but that's probably only in your head) as you get to \"see\" more information from the same angle - the true holographic sound stage presentation; the naturalness of sound is not heard anywhere else in the sense that these tubes tell you what IS and what IS NOT in your sound, e.g. you can tell the sound of natural rain in some movies from the sound of fake rain (water poured from hoses above the stage) in other movies; the clarity of sound is \"clinical\" - as in how your doctor would say you are either sick or not sick and there's absolutely no uncertainty or ambiguity in between and perhaps this is why they can get punishing to lossy digital sound sources; the musicality is unequalled as by now the only thing left in your music for you to hear is EVERYTHING in your music as long as the sound source is right. \u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan style=\"font-family: Arial;

Dedicated CD transport or lossless formats (FLAC, ALAC, WAVE etc.) on PC\/Mac (not on mobile devices) are recommended if you want to fully unleash these tubes' amazing power in your system.

the angled getter support seems to have \"bent\" the sound stage into a flattened panoramic view, which is still holographic but is much wider and holds so much more information about your sound: everything can be heard (or rather \"seen\"), whether you knew it existed before or not, or whether you think it should exist or not; the naturalness of sound is not heard on any other tubes in the sense that these tubes tell you what IS and what IS NOT in your sound, e.g. you can tell the differences between the sound of natural rain in some movies and the sound of fake rain (water poured from hoses above the stage) in other movies; the clarity of sound is \"clinical\" - as in how your doctor would say you are either sick or not sick and absolutely no muddiness or ambiguity in between should be allowed - perhaps that's why they can get punishing to lossy digital sound sources; the musicality is unequalled as by now the only thing left in your music for you to hear is EVERYTHING in your music as long as the sound source is right.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e \u003c\/p\u003e\n\u003cdiv\u003e\u003cspan style=\"color: rgb(255, 128, 0);

While as quiet and analytical as the best Telefunken E88CC tubes, Siemens E88CC's produce a warmer, smoother and more musical sound. To see how they compare to each other, please also see Soundlumia's exclusive Telefunken E88CC listings.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cb style=\"color: rgb(42, 99, 58);\"\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eProfessional Sound Evaluation\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eThe pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e - \u003cb\u003eAmplification: Liquid Platinum Tube Amplifier by Alex Cavalli\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e - Output: Focal Clear MG Pro open-back headphones\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eOur full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above. \u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb style=\"color: rgb(42, 99, 58);\"\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eProfessional Tube Testing\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003ca name=\"_Hlk169732138\"\u003e\u003cspan style=\"font-size: 14pt; font-family: Arial, sans-serif;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ca name=\"_Hlk169732138\"\u003e\u003cspan style=\"font-size: 14pt; font-family: Arial, sans-serif;\"\u003eThis set was tested and certified by \u003cb\u003eRoeTest V11 Professional Tube Testing System\u003c\/b\u003e with the following result: \u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eTube 1: \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eMeasured transconductance(GM): 8.17\/10.86 mA\/V - 65%\/87% (100% = 12.5 mA\/V)\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eMeasured plate current(IA): 8.812\/13.972 mA - 59%\/93% (100% = 15 mA)\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eNO shorts, leakage or gas.

the 30° getter support seems to have \"bent\" the sound stage into a flattened panoramic view, which is still holographic but is much wider and holds so much more information about your sound: everything can be heard (or rather \"seen\"), whether you knew it existed before or not, or whether you think it should exist or not; the naturalness of sound is not heard on any other tubes in the sense that these tubes tell you what IS and what IS NOT in your sound, e.g. you can tell the differences between the sound of natural rain in some movies and the sound of fake rain (water poured from hoses above the stage) in other movies; the clarity of sound is \"clinical\" - as in how your doctor would say you are either sick or not sick and absolutely no muddiness or ambiguity in between should be allowed - perhaps that's why they can get punishing (luckily not as much as the 45° angled version) to lossy digital sound sources; the musicality is unequalled as by now the only thing left in your music for you to hear is EVERYTHING in your music as long as the sound source is right. \u003c\/span\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt;
