Soundlumia's Opinion

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 is unequivocally the supreme commander of the entire ECC88/6DJ8 tubes family. This gorgeous pair is from the early 1960s' Ulm, Germany production - the most sought after Telefunken sound. 

Like any other Telefunken tubes, these ECC88'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.
