As a Proton AA-1150 (the fifty-watt version) owner, I would not hesitate...

BTW, if the D-1200 is a scaled-up version of the AA-1150, it may not be true dual-mono. The two power supplies in the AA-1150 look different, and I found out that one of them is for the DPD, the other for normal operation. I don't know if the D-1200 follows the same rule, but the DPD must get power from somewhere...

Yeah, I would, if the deal is good enuff. But I'm a sellout on PL, would use the Proton in the bedroom system.

 

[K-5BLAZER]

I do not know if 475 is a deal or not but this one (DOSE HAVE THE BRIDGE SWITCH) on the back if I herd right not all of these got that only the early ones

I would love to see a wopl tested with one of these https://www.wccaraudio.com/smd-amp-dyno-ad-1.html or one of these https://www.wccaraudio.com/smd-audio-multimeter-amm-1.html

I have one without the bridging switch. It's an awesome amp. It'll never replace my wopl, but it definitely is a force to be reckoned with. Super sexy looking too with the big green meters. The one weak link is the inputs. As mentioned in the video, they are just solder mounted to the board. Piss poor design on that but easily remedied. I bought mine about 9 years ago from a friend's speaker shop going out of business. I paid $470 for the amp, preamp, and tuner. The pre and tuner were nothing special other than the tuner has some kind of Schotz circuitry, whatever that is. The amp has a trim piece that's anodized aluminum that fades to a bronze color over time. It doesn't look bad this way though. I'm sure it needs recapped though. All in all, I think it's a fine amp that's under the radar often overlooked. You really don't see these turn up too often. If I was interested, I'd grab it.
