What is the best solid state amplifier you have ever heard?

Accuphase pre and power driving b&w matrix floorstanders and being fed by Linn lp12 lingo with some 5 tone arm and ortofon hohmann cartridge. All connected with siltech cabling. This was back in the 1980s .

I haven't heard that many and I tend to prefer tubes myself. With that caveat and the obvious fact I heard each of these with a significant amount of time in between and on completely different speakers/setups:

4) Sugden amps sounded really nice
3) Pass Labs XA30.5 (haven't heard the .8)
2) Pass Labs XA25
1) Nagra Classic Series sounded sublime

amp/speaker synergy makes too much of a difference to pick just one.

Exactly

I just recently acquired and have had the pleasure of "listening" to my 47 Laboratory Midnight Blue combo: the 4733 & 4734.  This set is special together but I have been recently using just the 4733 (Amp/Pre/headphone amp) with the newly arrived Sparkler Audio S301B diva' and what a spectacular combo.  I still cannot believe the quality & quantity of sound reproduced with only 2wpc...I have finally found what I was looking for in a small system.  so, my short run of solid state amps, integrated, etc has come to an end (maybe).  Thinking about what a Sparkler Audio Ether @ 7wpc would be like...Here we go again...
Cheers
