Newbee: I didn't say the EH KT88 were a replacement for anything. I just stated they sounded sterile, clinical or analytical and lacking in bass in my amp compared to other KT88. Don't get me wrong they have bass just not enough of it. The Gold Lion KT88 sounded MUCH better and a more balanced tube from top to bottom. I have not tried any of the KT88 you mentioned however, have heard the TS 6550 is a nice tube.
Oh and the Gold Lion KT77 is a very nice tube and I think you would love it. It is more of a hybrid tube between the KT88 and EL34.
