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. 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;

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;

As much as we love the overwhelming details made possible by these bad boys, please be aware they show no mercy to any lossy digital sound sources such as high-definition streaming video\/audio, and distortion in sound during playback can be heard. 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. Phono, if available, is highly recommended to be used as sound source because analog input is lossless by definition.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt;

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);

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 ECC83 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 ECC83 tubes, Siemens ECC88's produce a warmer, smoother and more musical sound.

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. One may find Telefunken's mid-range thinner compared to Valvo Hamburg as a trade-off of a more enveloping and curvier holographic sound stage...the law of physics applies here as well - the shape of sound can only change in one direction. \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\u003cdiv\u003e\n\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"color: rgb(255, 128, 0); font-family: Arial; font-size: large;\"\u003e\u003cb\u003ePair ( \u003cspan\u003ePre-1955 mCP - NOS+\u003c\/span\u003e )\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"color: rgb(255, 128, 0); font-family: Arial; font-size: large;\"\u003e\u003cb\u003e1x Valvo ECC83 12AX7 Long Plates D-Foil Getter -Hamburg 1955 mCP - Tests NOS+\u003cbr\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"color: rgb(255, 128, 0); font-family: Arial; font-size: large;\"\u003e\u003cb\u003e$513.00\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0809\/2388\/5888\/files\/6fb53c51539b47559cf0d122a832cf63_1aabd86d-6db5-44f1-88d6-a274e6e31add.png?v=1755875345\" alt=\"\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"color: rgb(255, 128, 0); font-family: Arial; font-size: large;\"\u003e\u003cb\u003ePair ( Orig.

Bass is incredibly deep but well controlled and feels as accurate as on the high end German ECC83's (Siemens, Telefunken, Valvo etc.) Thanks to the very 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!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e \u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt;

And the most defining sound characteristic of Siemens ECC83 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 ECC83's, Siemens tubes produce a warmer, smoother and more musical sound.

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 ECC83 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 ECC83's, Siemens tubes produce a warmer, smoother and more musical sound.

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. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\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 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. \u003c\/span\u003e\u003cspan style=\"font-family: Arial;

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.

So here is the answer: the late 1950s and very early 1960s tone, the beginning of over a decade's excellence in sound, the classic tonal template for all the great (and greater) Amperex\/Philips\/Valvo\/Miniwatt tubes to be made in the years to come, the timeless Philips radio tone that many of us grew up listening to. \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"color: rgb(0, 0, 0); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; text-transform: none; white-space: normal; word-spacing: 0px;\"\u003e\n\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"color: rgb(0, 0, 0); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; text-transform: none; white-space: normal; word-spacing: 0px;\"\u003e\n\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eThe most distinctive sound feature of the Heerlen ECC83's is the transparent, natural and expansive midrange presentation, with a slight touch of warmth that illuminates your music. 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\u003cspan style=\"font-family: Arial;

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. One may find Telefunken's midrange thinner compared to Valvo Hamburg as a trade-off of a more enveloping and curvier holographical sound stage...the law of physics applies here as well - the shape of sound can only change in one direction. \u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size: large;\"\u003e\u003cb style=\"color: rgb(42, 99, 58);\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eProduct Description\u003c\/span\u003e\u003c\/b\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;\"\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 id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cimg alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0809\/2388\/5888\/files\/75d35b11-0232-4ac7-bde4-7238e1bd57e8.png?v=1760038544\" alt=\"\"\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\u003cdiv\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cb\u003e\u003cspan style=\"font-family: Arial, sans-serif; color: blue;\"\u003e\u003cspan style=\"font-size: large;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\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 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 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 id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv id=\"ds_div\"\u003e\n\u003cp\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\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\n\u003c\/div\u003e","brand":"Valvo","offers":[{"title":"Default Title","offer_id":51149523386688,"sku":"267423768205","price":771.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/2388\/5888\/files\/57_0f782dc9-8f31-40a2-9e60-e5b04fe7bf82.jpg?v=1760038086"},{"product_id":"valvo-ecc83-12ax7-long-plates-30-o-getter-mc2-hamburg","title":"Valvo ECC83 12AX7 Long Plates 30° O-getter mC2 - Hamburg","description":"\u003cdiv\u003e\n\u003cb style=\"color: rgb(42, 99, 58); font-family: Arial; font-size: large;\"\u003eSoundlumia's Opinion\u003c\/b\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-family: Arial; font-size: large;\"\u003eCompared to their 45° angled big brother, these \"ultra clarity\" tubes are much more merciful at lossy digital sound sources such as high-definition streaming video\/audio.

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\u003cspan style=\"font-family: Arial;
