Just looking for some opinions here: I have a restored Sansui AU-7900, a Phase Linear 4000 in the shop, and an unrestored Harman-Kardon Citation 11. Running a Denon 1200 with a Shure V15 type lV cartridge through a Citation 2 and a PL-400. Wondering about your experiences with these; and, more specifically, should I take the H-K in for restoration or let it go on down the road.
