The "Crown Jewelry" ECC82 tube is here! If you've been seeking the reference tube sound then look no further. Designed for high end amplifiers and preamplifiers, Telefunken ECC82 provides high level gain with ultra low noise and are unquestionably the most sought-after vintage tube and treasured by audio professionals and enthusiasts.
Like any other Telefunken tubes, these ECC82's 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.
