I believe this is the first ZMF | Decware OTL amplifier to hit classifieds! Condition is like-new, and the unit has very few hours on it. It sounds absolutely sublime on my Atrium Closed, and it pairs incredibly well with the ZMF dynamic headphones.

If you're not already familiar with it, see goldwerger's review here: https://www.head-fi.org/showcase/decware-zmf-reference-otl.26421/

Retail is $4,199, I'm here asking $3,400 shipped in the USA. If you happen to be at CanJam in New York this weekend, I can do an in-person transaction, and since it saves me the shipping charges I'll do $3,250.
