Perfect matched & balanced pair of vintage Telefunken E88CC/6922 Audio Tubes - Ulm 1963 - Strong NOS Tubes Summary Behold the illumination at night, write down how your music sounds the moment these tubes start glowing and keep your notes forever. The finest in the fleet, Telefunken E88CC is unequivocally the supreme commander of the entire E88CC/6922 tubes family. This gorgeous pair is from the early 1960s Ulm, Germany production - the most sought after Telefunken sound. Sound Characteristics Like any other Telefunken tubes, these E88CCs are very 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. Lastly, it never gets old to say that no other brand is even close to these when it comes to low noise - Telefunken tubes are extremely quiet just as legend has it. At this level of the game, the only possible upgrade path from these tubes is the 45° angled support version of Telefunken E88CC, of which we do have a wonderful pair from the same year listed here: https://www.ebay.com/itm/266252618250 Appearance & cosmetic condition Beside the world-class sound characteristics, we treasure this pair also because the near pristine condition of inscriptions on the tubes. Ulm factory date codes are 100% visible on both tubes: U8003204H (U = Ulm, Germany, 3 = 1963) U620321?? (U = Ulm, Germany, 3 = 1963) And of course the diamond mark on bottom - the symbol of the best sound one can ever find on E88CCs. Professional Sound Evaluation The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC - Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli - Output: Clear Focal MG Pro open-back headphones Our 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. Professional Tube Testing Both tubes tested Strong NOS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 13,800/14,200 Tube 2: 13,900/13,900 Good tubes start around 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and Mercury 2000s rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers would mean to your sound experience, its actually quite straightforward: mutual conductance directly translates to a tubes ability to amplify sound so the higher the numbers the stronger.
