Is there a Solid State amp that can satisfy a SET guy?


Have been a SET guy for so long I have forgotten what a good SS amp even sounds like.
Just bought a pair of $33k speakers that will replace my current $16k speakers. Both are from the same designer and both are 92db and a flat 8 ohms. The new ones arrive in 4 days!
My 300B based amps well drive my current speakers even though I do use the system nightly as a 2 channel home theater. Especially considering the HT usage, I think I may enjoy a SS amp with many times the horsepower. The speaker designer suggests using a Leema Hydra II. I have written to Leema telling them of my 300B preference and they assure me that their amp does not have the destructive harmonics that make a SS amp bright. There must be other SS amps that can satisfy?

- Don’t go for single tube 211, 845 SETs, they sound slow and boring.
- Pani’s recommendations are dead-on and mimic my experiences exactly.
- I have been turned off by owning what should have been a really good sounding amp, the Viva Solista 845 based SET. Yes, it was boring compared to my 300B SET.
- I had the same experience with a De Havilland 845. It was a bore


@pani @eaglejo @mglik @roxy54

What do you attribute the above to? Would like to learn what might be going on with respect the amps you found behaving this way and (perhaps) speaker pairing, etc. synergy? Thanks.

I have no experience with 211 or 845 amps, but I would speculate that in **some** cases an explanation of why **some** of those amps may sound "slow and boring" compared to 300B amps derives from something Ralph ( @atmasphere ) has pointed out in the past.

What he has pointed out (and it makes perfect sense to me) is that since the distortion produced by a 300B (or other low powered SET amp) rises dramatically as output power becomes a significant fraction of its capability, while also becoming vanishingly small at low power levels, and since our hearing mechanisms use certain harmonic distortion components as loudness cues, from a subjective standpoint such amps will tend to have a greater perceived contrast between high volume peaks and softer notes.

In other words, dynamics will seem to be enhanced relative to the presentation of many other kinds of amps.

While if everything else is equal (including speaker efficiency and listening volume) that effect will occur to a much smaller degree, if at all, with a more powerful 211 or 845 SET amp, since the amp will be operating at a relatively small fraction of its power capability even on high volume peaks.

@almarg Thanks!

Can I therefore surmise that the 211 / 845 amps are more accurate and more honestly representing the recording, than say a 300B?

Thank you.

Yes, David, that is a correct interpretation.  Assuming, of course, that the effect Ralph has described is not overshadowed by other variables in the designs of the specific amps being compared.  For example, differences in the quality of the output transformers, since the high voltages at which 211s and 845s operate makes it harder (and more expensive) to produce transformers providing comparable performance to those used in 300B amps.

Hi Al,
I am not technically oriented much.
Only subjectively judge according to what I hear.
I do trust my ears. For me, I believe I know and understand what music sounds like. What I hear in well designed 300B SETs is a sound that comes close to what I hear in real life. It is not only a response through my ears, it affects my nervous system. I am not easy with sound that strikes me as unnatural. When I listen to a nice recording of a beautiful human voice I relax. It is sublime.
