A lot of hot AIR from Devialet?

[Damon]

I was in the shop today, chatting with my favourite Devialet dealer. We had a brief bit of that same soft, dry crackling sound that I noticed the other day. His system is fully wired, iMac > ethernet > Devialet. He pulled the SD card, and reinserted it, and the noise went away. I cannot remember the specifics of his explanation, but it concerned streaming and buffering. Just wanted to relate this experience, and note that it is clearly not the DWN and that it can occur without any wireless link in the chain.
