I tried to build two of theses a few years ago. They sounded pretty good, not great. I could never get rid of the hum they made. I threw the book at both of them and finally gave up. I think the problems is with the PS. YMMV

If properly built, no.

Time spent in choosing a power supply will pay off big time when it comes to a quiet line stage, I'm stuck in these decisions right now
