Diana Krall….rotating through her stable of cd’s, and comparing the audio performance directly against the hi-def streaming versions on QOBUZ.,
IMO it’s an interesting bake-off between a very high-end cdp/dac ( REGA ISIS VALVE cdp/dac) against a quality build and performance from a high-end MOON MIND2 network player/streamer/ dac
The wild card ad-hoc influencers:
- the quality of the recording digital actual mastering , or remastering. That in turn has three subsets therein:
(a) Think skill of the engineer in recording /re-mastering the digital files and cd.
-(b) XRCD silver disks versions are a step-up from the usual red book cd version
- (c) Generally BUT not exclusively , 24/192 streamed files will generally best most 16/44 digital streamed files,….with reference to the points above
(d) the high-end dac in my REGA playing cd’s (especially XRCD) can frequently better the 24/192 streamed version….with reference to the points above .
