White noise happen when using DSP/sample rate set as max PCM rate.
It occurs when track file change from non-MQA to MQA(Tidal) files, and also from MQA to non-MQA files.
When stop DSP, this issue not occur.
Chord user here.
Chord DACs don’t use off the shelf DAC chips.
ie: They do things differently.
Chord engineer/designer Rob Watts cautions against using 3rd party DSP and upsampling for his DACs (the switching noise you’re experiencing is a known consequence of this) and goes as far as to say they will sound better without such processing as they are already upsampling internally.
I’ve found this to be true
I forgot to include that using certain DSP with MQA is known to cause issues as well (on all DACs).
Have you tried disabling Roon’s MQA Core Decoder in the advanced tab of Device Settings?
I think if you disable that you cannot do DSP anymore. If I remember right. Roon needs that so to unfold the mqa, does DSP, them encapsulates back to mqa for the MQA ready dac
Normally yes except Roon can re-add the MQA signalling after applying DSP but only if Roon is handling core decoding. I believe Roon is the only player that can do this.
