SET Lovers, what's the one solid state amp you love(d)?

I'm thinking of trying out a solid state amp in place of my 300B SET, which is giving me some problems again and the builder is swamped so it's going to be awhile.

Suggestions? Speakers are 96dB 12" 2-way bass reflex studio monitors from a Japanese recording studio.


I made the switch to Class D with a pair of AGD Audion monoblocks. These amps are the best I’ve had in my system by some margin. Firstly, they produce no hiss/hum which has been a problem as I have high efficiency speakers. The sound is almost tube-like but is even better!. Soundstage, dynamics and detail are terrific.

I’ve used and loved SET/OTL tube amps for over 20 years but the new generation of Class D amps use less energy, produce virtually no heat and don’t need replacement tubes. So, for me, there’s no going back and I can’t see a downside.

I was amplifying the mids and highs of my triamplified DIY horn speakers with Cary Audio 2a3 SET monoblocks then I bought a pair of First Watt F3 single ended, single gain stage, class A stereo amps with VFET output transistors to replace the SET Carys after one of them caught fire.  That was years ago, and I have never regretted the change.  They sound excellent.

I am yet to hear a Class D amp that does not sound rhythmically and musically disjointed.If anything the newer Purifi ones sound worse in that regard than the Hypex.Everything else might be better but if you listen to rhythmically intricate music played by good musicians you will hear how peculiar they sound.A lot of people seem not to notice that but it does not mean it is OK.My guess is if you have no sense of rhythm and are a poor dancer then Class D might be fine for you!

Of course a lot of SETS are weak in that area too-although they tend to sound more slow/plodding than disjointed.My Almarro 318B was pretty good in that area but I have used some that were pretty terrible-an Audio Note Kit 1 300B and Consonance Cyber 845 monoblocks for example.
