SET 45 Amp Driving Dynamic Speakers

Hi Inna,
I appreciate your input and perspective. At the end of the day we all develop audio systems that reflect our sonic destinations. From reading various post from you I realize you ideal setup would favor high power tube 0r SS amplifiers, I understand that choice .We have very likely experienced different outcomes with low power tube amplifiers, no problem.

My last owned transistor amplifier was a Symphonic Line RG7. It was a very fine amp. In my listening it doesn’t measure up to my current SET amplifier overall and particularly in the areas that matter most to me. Common sense and experience dictate that no amplifier or component is without some flaw and thus compromised. Given your objectives I believe you’d prefer the Symphonic Line, I get that. No matter how you cut it ultimately selection is based on what we hear in our systems. As is evident here that will vary greatly amongst listeners.
Charles,

Hi Charles,
Yes, I would prefer high powered tube or hybrid amp. However, ideally I would have two different systems. One system is a compromise too. The music I listen to varies from acoustic guitar and vocal to world music to jazz fusion. The amp doesn't have to be insanely powerful, just great 100 watts and efficient enough speakers. For medium size room this would be just right.
Symphonic Line I might try too later if I can find it, or older Gryphon, before I go with tubes or Lamm hybrid.
I appreciate your input too and understand , I think, what you are saying.

Inna,
I hope you have an opportunity to hear a Symphonic Line power amplifier. They’re very high quality solid state designs  and I believe you will  be impressed with them.
Charles,

The idea would be to upgrade my Redgum integrated with better integrated, preferably with Symphonic Line or Gryphon, or perhaps Gamut or Vitus. I also would like to replace my AcousTech phono with a tube one, an excellent tube one, Lamm or VAC etc. And then go with top level separates. I guess, Ypsilon will be out of reach unless one day I can find a used integrated. Still, I would most likely prefer Lamm of VAC or Atma-Shere separates to Ypsilon integrated, or it just might be different.
