I've had good results with Motorola MUR4100E ultra-fast recovery diodes in a conventional bridge. They're quiet in my amp. I have not used snubbers but there is a 0.1uF 1000v cap across the rectifier output, in parallel with the first smoothing cap in a CLC filter.My amp is a fully balanced (differential and P-P) design, so there are no unbalanced stages anywhere. I guess any power supply noise will be common mode, so maybe that's why there's no audible noise through the speakers. If I had a single ended design, then the noise from the PS might be a problem, I don't know.
