sorry...wasn't online for a while.
my AVP is at my dealer (Audio Outlet in Mt. Kisco, NY, and btw Mike, these guys are great). i will pick it up saturday morning.
the upgrade kit consists of a large printed circuit board (approx 8" x 10"), with tons of surface mounted devices (DAC's, etc) plus all the output female connectors. beyond that there's just a few wiring harnesses, a new AVP2 owners manual, and a metal backplate with serial number. the new software is already installed. i think the big board replaces what was before 3 or 4 small boards. overall it looks pretty plug and play.
as for pricing Pesto....i am also buying the PMDT and some cables, so i am getting a small overall discount. in my experience, the best you can do from an authorized madrigal dealer is 10%.
is it "worth" it.........???? will find out tomorrow! given that there is basically zero value to the old boards, i would have to say that yes...getting half the guts of an AVP2 probably is fair at $2500. i am expecting a subtle but audible improvement. i have yet to be disappointed by any Magrigal products (as others seem to have been). i think they sound and look great and are priced competitively.
