For deep bass, linearity and clarity consider the SED 6550's. In my PL3/5 combo I preferred them over SED KT88's (I agree with your description). Also, don't forget to fiddle with the small tubes - A small tube with a bright balance won't help you with the SED KT88's nor the 6550's for that matter. FWIW.

Here is my dilemma.I was happy with the performance of the "stock" KT-88s in the PL2(Chinese Genelex re-issue-I believe).Somewhat darker and subtractive of fine detail-in absolute terms.I had the opportunity to hear the Svetlana "winged c"s.These brought about a more lively and detailed midrange/midbass,but they were "forward" in the upper frequencies and this was unacceptable during long-term listening.
So my question comes down to this.Can anyone give me some insight into the harmonic balance of the following KT-88 versions:
Genelex Gold Lion re-issue (Russia)
Genelex /GEC labeled
Shanguang KT-88/98
Any others to consider ??
Can anyone differentiate Gold Lion/Gold Monarch and the GEC versions.I see some were made by Mullard as opposed to Genelex.
I realize that the 1950/60s Genelex are very expensive,but over the long-haul would they be the choice.
Looking for a more detailed mid/bass,without adding any forwardness/brightness on top(smooth/slightly sweet).
Thanks in advance to anyone willing to share their experiences.
