MQA files turning DSP off?

[miguelito (Miguel Barrio)]

I haven’t seen any info to assume/guess that A+ is different to Roon right now, with upsampling MQA files.

Both will tell you that it’s an MQA file that is being upsampled but there’s no ‘additional’ info in A+ to tell you it is upsampling the first unfold (if you are doing upsampling).

Hmmm… You raise a good point here… If I recall correctly, you can choose between:
1- No MQA Device – First unfold and (I expect) upsample
2- MQA Renderer – First unfold, no upsample
3- MQA Passthrough – Signal untouched
(exact wording escapes me now)
Choosing 2 or 3 surely must avoid any upsampling or else it would not be able to render or decode respectively.
