The Music Reference RM9, MKI, MKII were great as were the ARC, and the PSE were superb for the money. Missing is the Quicksilver Silver mono, the M135, M60, M80. They needed the caps changed out and the Rel caps replaced as there are better ones now. These were superb because nearly all of them are in use today with a cult following due to the point to point wiring and not having a board burn out and no replacement available. The B&K are also great. Krell ahd some good ones, VAC and the PA90,
