I also use a KT88 single ended amp. In regard to current production, I really like the Gold Lion reissue. What particularly do you like better about the SE KT88's? I've rolled a lot of tubes in that amp & may be interested in trying the SE as well. The best I've heard (in that amp) is an old pair of Tung Sol 6550's. Absolutely beautiful mid range. The old GE 6550's are not far off from the Tung Sols. The Gold Lion KT88 reissue doesn't have as much midrange warmth, but its no underachiever there & does exhibit more detail than the 6550's listed above. It also does that without being etched in any way.
