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


Title says it all. I own a variety of audio equipment I bought here on Audiogon. And through the years, have never seen another for sale.                 
Example: Audio Research SP-15 bought it from here in early 2009. Another item, Kuzma Stabi Stogi S TT (from Audiogon, close enough the fella delivered it for $20. Never seen another. Then a Rudistor RPX-33 MK2. (it is a headamp from Italy) And an Adcom DA700 Finally just this week saw one for sale. only the second in 18 years since I bought mine from Audiogon.  
So you have any rarities you bought here and just never have seen another for sale?

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. 
VAC 22.1 vacuum tube dac.  Hdcd decoding using the Pacific Microsonics pmd 1000 dac chip.  It doesn’t get a lot of use these days but still sounds decent.  An unusual piece for sure.
