OK, I'll bite... I have to be careful because I am sort of a quasi professional at this now. It seems I have a second career rebuilding people's tube gear - mostly Citation stuff. No, I am not trolling for work! Anyway, I had a long list of SS gear over the years. Heard/drooled over Mark Levinson stuff, big Krells, etc..
Owned:
Hafler DH220 I built.
custom op amp preamp (LF456BN op amps if I recall)
Rotel something - mid priced power amp
Again, heard a bunch of really nice SS gear and then system culminated with Krell 300i integrated. Not bad. Then got the tube bug so bought a big Jolida integrated tube amp (100 wpc I think the 1000 was the model). Blew the Krell away for musicality. Then got a killer custom built preamp from Albert at SpaceTech Labs in Vancouver - all octals with a tube power supply that I still use and one of his EL34 based power amps. This combo was way better than anything I ever heard. Then I started reading about tube amps and found a H-K Citation V to rebuild with all the McShane kits. Whoa.... a whole new level. Then I finally found a Citation II to rebuild. I have yet to hear a better amp at any price so far, but that is just my opinion. I have now rebuilt 8 of them for people. I have also rebuilt a number of Citation I preamps for 5 people and I own one that I use with the V in a basement system. The Citation I is wonderful when re-capped, re-resistored, and the power supply updated, and the phono section is first rate. There.....I bit. Oh, also have done 2 Sansui 1000a receivers. When re-done, they are way better than any receiver has a right to sound. In fact most of the 7591 based receivers of that late tube era are very good when running up to spec.
cheers,
