Re: Amplifier Building vs old and used?
Assuming the single tranny is properly rated for the load impedances presented by the speakers, don't agree. If the idea is to get better separation and headroom between channels, and assuming teh single xformer is properly rated, just use sufficient capacitance on the power rails. Way cheaper and more effective than 2 xformers. Multi xformers only make sense if you have them and don't want to buy a higher rated single. One of the 2Bs had been modded with 2 tranny's, I pulled one out and went back to single.
Maybe that's some of it, but mine was failry powerful and well heat sinked. I listened with it for weeks and it just sounds like an old cheap amp to me. It's hard to describe, but its "grey", not clear sounding. The chip-amp guys swear you need boutique parts to make them sound good, but this had standard r's and c's (name brand, but not fancy). The other thing I really don't like about some of the chip amps is the overload protection circuit (National called it "Spike") which starts to cut maximum output voltage with operation below 4 ohms. I made sure to only use it into speakers that didn't trigger Spike protection
I was only comparing amps that I mentioned directly in my post. I've listened to all those amps in my post for many months or many years (1 NAD and 1 Bryston for 3 decades) except the LJM amp which I only heard for a couple hours. The ClassDAudio I haven't heard yet but trust positive opinions I hear of it, and given its similar to the LJM, trust that feedback. I almost bought one but bought ncores instead. I offered no opinions on amps mentioned by the other posters, so can't really help you with those
