Curious.. anyone still have one of these?  Years ago I used to love bringing my HD580 to meets and listening to this amp.  There were always 2-3 at local meets here in the bay area.

I think Purk still has one... 
 
I nearly bought one when Singlepower first started business.  Glad I didn't.  The first indications of poor build quality started with these amps.  People opened them up and saw a ridiculous pile of spaghetti that was the circuit.  Then they stopped doing PTP and went to PCBs for a while, if I remember right.  Then back to PTP?  I could be wrong about that. 
 
The fact is, though, that it sounded pretty good.  Unfortunately, it was also potentially lethal.
