Lowrider, How much time do you have on the amp? Break in of tubes as well as the amp itself is quite important. If you have less than 100 hours on a new tube amp I'd reserve judgment. Ultimately though you might roll in some warmer power tubes (I like SED KT88's) and/or some NOS small tubes.
Tube rolling in Cayin A-88T
Anyone changed out the stock KT-88 tubes?What have you found that beats the stock jobs?..I understand Cayin uses the Shuguang KT-88. As good as these are, they are the 3 hole plate which is said to be inferior to the solid plate version. Can anyone comment in regards to what they are using? Thanks.
