I need to get this off my chest. The Bryston amp is hurting a bit. As is the ARC preamp. The SP-14 preamp won’t go out of “bypass” mode into “normal” mode anymore. If you flip the “bypass” switch to “normal” you get nothing. No sound whatsoever. Never mind that I never listen to it in normal mode. I always use bypass, so, for me, it still works. There’s just the angst of knowing it doesn’t work in a mode that, frankly, I would never use. And what does “bypass” actually bypass? Well, the balance control for one, and the mode switch. If you’re in bypass mode, forget about reversing the left and right channels. I never did understand the need for that feature. Now, an absolute polarity switch – there’s a two-channel hot button topic that could easily fill a Rosetta stone. But alas, that’s not to be had either, even when “normal” worked, well, normally.
