Thanks (I think). There's an interesting recent thread on the Belleson regulators at
DIYAudio (great site). There was some probing scepticism about the test results Belleson gave, and one of their gurus worked through the issues in a professional and convincing way. I think the end result was the performance of the superregulator was generally accepted to be even better than Belleson had originally been claiming. There are lots of high-performing regulators out there, but the Belleson sounds like the one to have.
This made me look closer at the FG Elektronik supplies. Apart from the NMC 102 and the ultra-linear modules, they're nothing special, and might make a good platform for modification. They're attractive because of the combination of current/voltage capacity, and the physical form factor. Better regs will probably make them better, but to put things in perspective, a single Belleson super reg is more expensive than the whole Power One 105W supply that fills my 861V2, and transforms its performance. That doesn't mean the Bellesons aren't good value though
I'm confident that there's more performance to be had, but even the oldest and most basic linear supply is a huge improvement over any switching supply, both subjectively and objectively. The FG 905 supply has just arrived, which brightened an otherwise miserable day. Can't wait to get it in there.
