Looks like some of the work that I had done to a couple of mine in the past. I can see the extra amp board has been removed, the extra connectors removed, black gates in the power supply board, Auricaps installed, Eichmann speaker connectors, removal of the stock power cable, and new power cable connector installed etc.
A great little 30wpc Tripath, for those looking for some oomph!
Good luck with the sale.
http://www.audiocircle.com/index.php?topic=16230.0 - here is a link to my thoughts on a stock unit, and one lightly modded by Vinnie (now Red Wine Audio), and one modded by Wayne - the one modded by Wayne I reference appears to be similarly modded to this unit for sale here.
