Stuff you bought on Audiogon, but never have seen another?

When I bought the MFA (Moore, Frankland and Associates) Magus, we lived in the SF Bay Area. It gave me comfort to know that Scott Frankland (the “F” in MFA) was still working (doing repairs, etc) in the San Jose area. I don’t know if that is still true but, fortunately, the Magus continues to work fine. I use it with a Classe Audio DR-15 amp.

This is tricky -  I have gotten some relatively rare items on Audiogon (Symphonic Line Kraft 250 mono amplifiers, Accuphase PS-500 regenerator / conditioner, Stahl-Tek Vekian Opus DAC, Tidal Contriva Diacera SE speakers) but I cruise the audio ads somewhat frequently, so its hard to say I have never seen another (although I would be comfortable saying no more than a couple). 

However, here are several "sole" examples I can think of:

Silver Rock Phono preamplifier  (was Stereo Times review unit)
EASE / Counterpoint Magnum Opus phono premplifier (a Counterpoint SA-9 with upgraded parts and cosmetics - only a handful ever made)
Silver Rock TVC with two switchable inputs (almost all of them are one input)
Promitheus Signature TVC (with two chassis and copper plates - still kicking myself for selling it)

Following up on the above posts, am a fan of MFA as well - Scott Frankland (the "F" in MFA) is a stand up guy.
 

Don’t see much in the way of "audio innovations" product lying about....

Note (heh) the one line in the advert....:

"Audio Innovations was Peter Qvortrups first company before taking over Audionote UK."
Not really seen in the USA but much loved in Canada.

Pretty dang decent integrated for $600us. and, it has black velvet alps potentiometers/balance controls.

You can see by the layout that it is intelligently designed. Looks like it may never suffer thermal issues. That’s a good thing as other versions of it did suffer thermal problems. (800 series integrated, el34)

1) Voce audio V1 speakers - I bought the proto type from Vince & have never seen another pair offered.
2) Joule Electra Destiny mono amps - 310 wpc - I think only a dozen pairs were ever made (they could melt an igloo) 16 6C33B tubes per side.

@tonykay I have a Magus that I bought around 95. I only use it as a phonostage. I’ve had Scott Frankland upgrade it twice. A third time I gave it to him for a couple months to use as a test bed. He figured out a new mod he’d never done on any other. It’s much treasured but, if I had a chance on a Wavestream Kinetics phonostage, I’d jump.
