SET the best?


Is SET amplification where we should all end up? I keep reading posts where people tell of their journeys from plenty power to micro power, and how amazing SET amplification is 45 set 211 set 845 set otl, and usually, ....with the right speaker. I have yet to read of anyone who has gone the other direction from SET, to High watt beast class A amps or others.
If your speakers can be driven by minimal wattage, is this the most realistic, natural sound we can achieve? versus say, 86db sensitive speakers and a 1000w amp?
Is the end result solely based on speaker pairing? circuit? tubes?

I am in the process of changing my direction in my search for realistic sound, just because, and wondering if this really is the best direction to be going.
From what I have been reading I think it may be.

What do we get with SET? What do we give up?

What's you favorite color?

I think he is talking about the missing fundamental effect. If the fundamental frequency is f, there will be harmonics at 2f, 3f, 4f, and so on. Even if your system can not produce the fundamental (as has been pointed out, the bass note on a piano goes as low as 27.5Hz), it can definitely produce the harmonics which is how you perceive the bass note. Your brain fills it in.

I can listen to piano on my iPod earphones which definitely don't go as low as 27.5Hz, but I can still "hear" bass notes on the piano.

There are products out there that take advantage of the missing fundamental effect by boosting the harmonics, giving the sensation of more bass.
IMO if there is a subsonic rolloff, you hear it as a diminution of bass impact. It can also be measured quite easily- square wave tilt is the measurement. Having played around with LF cutoff frequencies a lot (our amps are full power to either 1Hz or 2Hz), all I can say is its easy to hear once you know what you are looking for provided you have speakers with bandwidth into the low 20s.
Thanks to both of you! I'll have to look for it next time I have my amp on the scope but I don't remember seeing a tilt.
For me it was.

I had a few well revered ss amps (Rowland, Threshold,...) and auditioned many others (Levinson, Krell,...), but when I decided to go tube, without any auditioning, just out of curiosity from what I had read, like you, it was, in hindsight, one of the most revelatory experiences of my high-end audio journey. I was a convert from the first instrument, first voice and haven't looked back. I was in shock by just how real and natural the sound was and amazed that the bass actually trumped my ss amp. You always hear about how tube amps have no bass and that couldn't have been further from the truth. The bass from the tube amp was not only deeper, with more impact, it was also more musical, dynamic, tight, and fast. That last ss amp was the Rowland Model 10. Hard to believe a 15 watt hand made, point to point wired 572 Svetlana power tube monoblock amp embarrassed a 150wpc ss amp. But it did. And you'd think it'd have to for the price. It was the ViVa Verona Monoblocks. The ViVa absolutely demolished the Rowland in every which way. I had never heard music sound quite like that. Almost magical. The sound was nothing like I had heard before from ss. Now I knew what all the gushing talk over tube gear was about. After that I played around with some others (lower priced, both high and low power) and ended up with TRON Cantata 300B mono's, having had the TRON Jubilate monos just before that. I probably would have kept the ViVa had I decided to get more efficient speakers first instead of a more powerful tube amp (I had Kharma Ceramique 2.1's). Now I have 98dB Horning Agathon Ultimate speakers. Another revelation of sound and a design, like tubes, that makes most audiophiles skin crawl - horns. Again, nothing like I've heard before. I had Maggies for years and swore I'd never have traditional box cone driver speakers. But I kept an open ear and listened to one years back. That's all it took to hear that I was missing something. The horn speaker was as dramatic a transformation for speakers as tubes were with amps.
It's hard to understand how some audiophiles have such an aversion to tube gear in general, and in some cases plain prejudicial, without even hearing one. But thats' how some people are. They don't like change. Having been a ss audiophile for more years then with tubes I have to think it's just tradition, like those who think audiophiles are nuts and that there's no difference in sound with the HiFi gear, or cables,..etc. I think they're just in denial because it's so different to what they're used to. They don't want to believe what they're hearing. It's not ss so it can't be good. Speaking from my experience though, I have never heard such musical realism except at a live performance.
Back in the 'Sound Practices' day, I played with SE amps. 300B and 2A3. PP 6B4Gs too. Though pleasant sounding, I was forever trying to find a good speaker to match up with them. I tried different modern and vintage coaxials without success.

I eventually turned away from Triode SE and back into Ultralinear designs. The higher power worked better with my Altec 604 / Eminence speakers (ie - the UREI 813A). The best DIY design of mine was a SE EL156 UL with a pentode front end. Lots of power (~20Ws), fast, detailed but not clinical. This was nirvana for me.

Then I accidentally got a good deal on a Threshold S/500 amplifier. They gripped the UREI speakers better than any tube amp I have ever heard. No solid state glare or grain - and they have enough power to drive any speaker I would want.

So I sold my SE EL156 amps to a friend (where they are still churning away) and after twenty years of tube amps jumped on the solid state wagon. I'm not getting off either. Though lacking in some of the qualities that tube gear has, good solid-state also has it's own signature that appeals to me.
