I've got a Fiio K11 R2R and have been using the USB connection for a while now
My setup:
Tidal -> Wiim Ultra -> Fiio K11 R2R (NOS) -> Yamaha cx-1000 preamp -> 2 x NAD 218 THX amps (mono mode) -> Yamaha ns-1000m
Today I noticed a buzz coming from both woofers when using the Fiio.
I switched to using the Wiim internal DAC and the buzz was more obtrusive - now at midrange frequency. I eventually tried removing the USB connection from the Wiim and the buzz disappeared.
I then connected Wiim to Fiio using S/PDIF cable and the buzz then also disappeared when using the Fiio.
I had learnt to live with the very low level pops between songs when using the USB connection to the Fiio.
I set the sample rate switch latency to 100ms for the S/PDIF connection (something I had read on this forum) and I no longer get the pops between songs either.
I'm sticking with using the S/PDIF connection. The sound quality to me is as good - but I may be biased - as that buzzing was really annoying even if only just audible.
