EAT KT88 Diamond (Quad Set)
The Euro Audio Team has produced a KT88 tube that is in a league of its own.
The EAT KT88 Diamond tube is considered the best KT88 made, and by some, better than the original Genalex KT88 tube from Great Britain. This KT88 tube is available in factory-matched quartets. Its construction features include black plates, black metal base, and gold pins. The matched quartets come beautifully and securely packaged and include a 6 month warranty.
Ken Kessler in HiFi News:
"The EATs are sensational. Even though the measurements indicate no gain in power, the sound is more robust, with convincing weight and palpable mass, but the real gains were in the midband, the EATs increased intimacy strengthening the sensation of the singer being in the room. The extra clarity and openness make it much easier to focus on detail typically masked or overwhelmed by louder sounds. Then, there's the attack & decay capabilities of the EATs, they're quick, almost ridiculously so. Put on a disc by any virtuoso known for rapid plucking or fingering, no muddle, no delays, no upsetting the timing.What we have here, my friends, is the valve amp equivalent of Viagra."

Ratings & Reviews
Never ever had a better modern KT88. Turns amp to high end in every characteristics of sound. It looks to be quite expensive but worth every cents. 6 stars out of 5.
