the best sounding 211 tube is united electronics. btw I listened to ANUK Ongaku several times and I can say that it sounds good, silky smooth. it’s a wonderful amplifier but not like Kondo. Kondo is lively and better on every aspect.Try Amperex 211s. They are outstanding I think and I've done listening tests with others and they thought the same. Done against GE, KR, RCA etc.
