I'd love to try some KT77s but my tube budget is currently limited to known tubes.

If you have a ZMA it does a pretty good job as a "tube tester." †I sparked one of my 7581As and it was on the side that was requiring a lot of bias offset to bring the pair together. †

The way you describe "dry bass" suggests to me that I don't have that problem, generally. †Although, that could be why I never really liked KT66s in my amp. †(I always attributed it to relative mid range lack.)

I also found the new production kt66s somewhat recessed in the midrange, both in the ZMA and my lampizator DAC (which has a tube buffer). It was like female vocalists were a couple steps back from the band. Perhaps interestingly, I tried a pair of lightly used NOS GEC KT66s in the DAC and everything was noticeably better. Not the absolute best midrange but very good and it did so many other things remarkably well. Too expensive to consider in the ZMA though.

Iím also really happy with the 7027as but sometimes get an itch to change things. I plan to try the new production Gold Lion KT77s in the next couple months. Will post with thoughts if and when.

I've liked pretty much every tube I've tried better than KT66s.  Never had anything other than new Tung-Sol and Gold Lion though.
