I agree with Zd542. Just because an amp uses the same type of tube does not mean a thing! If that was the case then all amps would sound the same! More goes into the design of the amp than the type of tubes used. That being said, I do like the Quicksilver amps I have using KT88's or EL34's.
KT 150 Amp Options
It is tax return season, which usually means I immediately spend it all on a piece of equipment. I've been looking to upgrade to an amp that has been designed for the KT 150. They have been around for about 2 years now but I don't see a lot of amps designed for them. ARC came out with the REF 75 SE, which seems like a nice amp. However, I run an ARC SP3-C for my pre, which is an SE out. My understanding is the 75 is balanced which does not make them ideally compatible. I've been waiting for CJ to put out a KT 150, but am not sure if that is even on their radar. Any thoughts on a good KT 150 amp or any rumors on when the market will have some more options?
