I have a like new (two month old) Axiom passive preamp w/Caddock upgrade ($160), stereo RCA version. Single pair input/ouput. Selling for $100.
Btw, my version is made for systems that have high gain or sensitive speakers. In other words, if you find your current preamp too loud at anywhere from 9 o'clock to 12 o'clock positions, and would like more better control for late night listening then this preamp is for you. Also good for tubes/high efficiency systems too where an active preamp will add too much gain.
I've been using it with my (just sold) hornshoppe horns/2a3 SET amp combo with excellent results. Matter of fact it's the one preamp to not only add zero coloration, it's more dynamic than my other AES 6sn7 preamp I used to own, which really "slowed" things down. No such thing with the Axiom - fast, neutral, and transparent.
