Rich; organic true balanced amp w good detail $6k


Suggestions welcomed & appreciated- here are the Criteria:

- fully balanced architecture
- rich, organic sound, extended bass, silky highs, but not at the expense of obscuring detail
- No OTL (too many tubes/heat)
- SS (Class A bias) or tubes OK
- 20-200 wpc ok, the lower the better though all things being equal- well built power supply crucial
- stereo amp easier to put on my Sistrum rack, but mono-bock architecture also considered if better performance
- $6k or less used would be ideal, but would consider up to $8k used if there are no world-beating contenders at the $5k-$6k used price point

Preamp is a modded Sonic Frontiers Line 3- extremely neutral, hence the desire for a richer-sounding amp to balance. High efficiency speakers from Coincident- large open concept room (main floor of house). Re: tubes, have used ARC VT-100 MKIII- good- airy w big soundstage, but meatier mids would be better. Also had Wyetech Topaz 20-watt SET, superb, if slightly lean in the mids (and not fully balanced, but shows you how powerful 20 watts can sound with a well-built power supply) For SS, am considering Pass XA.5 series (they now can run balanced from what I understand?); Clayton Audio M-200 (but unfortunately over the price-range).

Thanks in advance for any suggestions- I have an open mind, so bring it on!

Hey Sutts, yeah, believe it or not when I tried Jmcgrogan I was prompted that the name was already taken.......makes me wonder if I signed up before I knew I did, or if there is another Jmcgrogan....perhaps and evil Jmcgrogan??? So I'm stuck with Jmcgrogan2....as in Jmcgrogan 2 channel. :)

Preamp is the aformentioned ARC Ref 3, speakers are Verity Auido Parsifal Encore circa 2004. Listening room is 24 X 14 X 9. Musical preference is jazz/blues/rock/folk/classical.
Main source is vinyl (Basis/ZYX/Walker), then digital (Marantz SA-11S1 w/ Ultimate mod from Underwood/pcX)

Cheers,

Bob_reynolds: Good Point about the output impedance of the Sonic Frontiers.. it might not match up with the Lamms as they are really sensitive. Typically less then 1volt to full volume
Belles amps are what you are looking for. His new monoblock amps are said to be his very best and sell for $6700 new for the pair.(Model --200) They are pretty small and run cool so they can be stacked on your rack.

They are said to sound better then the Reference line which in my experience proved to be some of the finest sounding amps I have heard.

The Belles M200 monos are getting lots of positive buzz. However, they are single ended only.

I mention it because the OP requested fully balanced as a prerequisite.
