Why not an isolation transformer? You can get 2kVa which is nearly 20 amp capacity for under $300.
Surge protection for Bryston amp
Looking for recommendations on a surge protector for my Bryston 4B-SST amp. Doesn't need "conditioning" as I'm very happy with the way it sounds and I need something that won't limit the dynamics. I'm currently plugging the amp into a Hubbell 8200 socket in the wall but obviously I'm not protected against surges & spikes. Monster HTS2000 is used on the cdp and preamp. Tried the HTS but felt it tamed the amp somewhat. Need something that protects first and foremost - budget $350 or less (new or used)
