Mains power and conditioning

[GuillaumeB]

Take a look at this which covers a noise sniffer and a Devialet and the PS Audio PPP.

Interestingly the PPP comes out well but the P10 (part of the replacement series) fares not too well.

That's really interesting Ian, thanks for sharing.

The trouble with these noise sniffers is that we don't really know exactly what they're measuring plus there is the issue of whether whatever it is actually measuring really matters to the Devialet... having said that I do think it's a good indication of the magnitude of mains noise generated by the Devialet's SMPS, whether its common mode mode, differential etc.

I did notice that the Devialet D-Premier according to your article does not seem to be that noisy... I wonder if with the latest generation of Devialets this has changed? The earlier Devialet white paper (claiming a very quiet SMPS) I think referred to the D-Premier.

As I said earlier using the AudioPrism device the Devialets (200 and 250) were off the chart!
