are there soft-recovery digital amps?

Propeller Head Plaza

Technical and scientific discussion of amps, cables and other topics.

I recall good slow-switching critically-damped soft-recovery diodes exist for rectifiers, which don't oscillate eliminating much swittching noise. Are there similar slower-switching Digital amps, which may broadcast less RFI? I invariably hear jitter type noise out of them. IMHO, the likely source is RFI wirelessly fedback globally contaminating the upstream analog input and/or rail voltages. I figure what we've learned by making good rectifiers could be adopted on swithing amplifiers even if only a Zobel before the output modulator/integrator/low-pass filter. I realize there's only so much one can slow switching down before creating a de-facto noise-gate, but certainly some should provide an audible improvement in continuity. It seems to me that reducing noise at the source would be a good thing, rather than trying to tweak it (in my case with Shakti:Stones).

You asked this before. - clifff 06:35:11 11/03/05 (5)

also did on TÂ² - Mart 07:45:58 11/03/05 (4)

You are perhaps confusing two things. - clifff 10:07:02 11/03/05 (3)

Minor elaboration to help with Mart's understanding... - Al Sekela 10:33:24 11/03/05 (2)

had thought the broadcast RFI were Fourier frequenies from hard-switching - Mart 04:59:57 11/04/05 (1)

Yes... - Al Sekela 10:37:08 11/04/05 (0)
