First of all, this is not my amp, but I've been wanting to see whether these guys find their way for sale and have had a saved eBay search-term for it. Someone has posted one for $399 un-tested but powers up. I don't know if this is the stepped attenuator model that ran $3,888 or the $3,333 standard version. I'd really really like to buy it, but I just don't have the need right now. My HeadRoom Triple Stack is still going strong, and I just don't have as much time to listen to as I used to.
