A lot of hot AIR from Devialet?

This is almost certainly a contributory factor but not prime. My amps were off (at the mains) for days, and before repowering I took the PS Adio PPPs out. Result: No white noise for just about the whole day. So much so that I thought the PPPs had been the cause (rather illogical I admit).

White noise re-emerged eventually. The contribution to minimal noise was the prolonged powering down, not the PPPs.

My analogy is a bath which fills up (faster with hi-res) and overflows ( = noise ). (And probably takes a long time to empty entirely.) Stop the music and start a minute later using 16/44.1 and there is no noise for quite a while. Start using hi-res and it is back quickly.

I agreed with Ian. It's very likely to do with the buffering. I'm almost certain that white noises/dropouts appeared when I played 24-bits files, which required more data buffering. For 16/44.1 files, I will only experience dropout once in a while, but always recoverable. Yesterday, I had an experience where only one particular music file is causing white noises. From the same music app, playing all other songs, there is no issue, only that particular song.

Thank you!

My regret is that Devialet has probably known this for many months and could have said so, thus saving lots of time for less well informed people like me and others, who have misguidedly been trying to help them.

Everyone makes mistakes and most people are understanding about that. Compounding that, by failing to communicate, simply removes that tolerance, especially when it goes on for months.
