So elusive they're even unheard of in many parts of the world. Not many of these tubes are around, either, let alone a strong matched pair! Although lesser known than big names like Telefunken and Siemens, they are just as remarkable as any other German-made tubes and have been the go-to tubes for guitar amplifier users. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eLike most German tubes, they are characterized by an impressive open \"air\" at the top end, and the soundstage is large, even in mono applications such as my classical vinyl records from the early '50s, these tubes  provides you with a full 3-D imaging. The midrange is ruler flat,  a.k.a. natural sound, and the bass is tight and accurate. One very unique feature of Lorenz tubes is the fine sense of dynamics you get from anything you play - it feels you are enveloped by an invisible \"musical body\" that you can't escape from and it's cerebrally joyful. Last but certainly not the least, as the legend goes for all the German tubes, these are astonishingly quiet. If you're seeking European ECC82\/12AU7 tubes with ultra low noise look no further. These will get the job done fantastically.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eProfessional Sound Evaluation\u003c\/span\u003e\u003c\/b\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eThis tube worked wonderfully and sounded terrific in our professional studio setup for monitoring. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e - Amplification: Handcrafted Bottlehead Crack Headphone amplifier\u003c\/span\u003e\u003c\/b\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e - Output: Neumann NDH 20 Closed Back Studio Headphones\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eOur full tube sound review was written 100% based on the actual listening experience while this tube was running in the system described above.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif; color: #ff6600;\"\u003eRound Logo\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif; color: #ff6600;\"\u003e***\u003cem\u003e\u003cstrong\u003eSOLD*\u003c\/strong\u003e**\u003c\/em\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif; color: #ff6600;\"\u003e1x Lorenz ECC82 12AU7 Pre-SEL Tube - Germany 1950s - Strong NOS\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif; color: #ff6600;\"\u003e$134\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eProfessional Tube Testing\u003c\/span\u003e\u003c\/b\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eThe tube tested \u003cb\u003eStrong NOS \u003c\/b\u003e(110%+ nominal mutual conductance) and perfectly balanced on a Mercury 2000 tube tester with the following result (mutual conductance in both uMhos and percentage of nominal):\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e3,490\/3,600 (116%\/120%)\u003c\/span\u003e\u003c\/b\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-size: 13.0pt; font-family: 'Arial',sans-serif;\"\u003eGood tubes start at \u003cb\u003e2000\u003c\/b\u003e and new tubes (incl.
