Does it matter if an amp has a linear power supply vs switching power supply? Starke AD4.320 vs NCore and ICEedge

After having had two brands of Actives I've gone off Class D and Switching supplies.

Back to linear non Class D and separates. Happy again.

What issues or what didn't you like about the Class D products you tried? Care to share the exact Class D products you were using?

Don't believe everything you read on a manufacturer's website...
Considering Benchmark's products are largely extremely good with regard to mains leakage and power supply hum, I don't think I'm out of line saying that they've put their money where their mouth is.

I can't speak to theory, but my swap of a linear supply to SMPS for my DIY ClassDAudio SDS-258 amp, (mainly to reduce weight), has been very successful: definitely no degradation in perceived sound quality in and maybe improvement. I don't know about longevity at this point.

Their products are good for sure.

But this display of absolute BS unfortunately is not conducive to furthering their reputation as honest...

All of us who have actually looked at, and scope'd the residual distortion from amplifiers made in the last 50 years can confidently say that fake "scope" shot is utter BS. It is, apparently 60dB, or 1000 times the residual, and honestly, even a grossly fugged-up low biased amplifer doesn't come remotely close to that plot Benchmark plaster all over their website.

He (John Siau) was called on it, a few years ago and went to ground with zero evidence.
