I have to agree with Dave. Datasat are clearly aiming for the RS20i to be the "best audio processor in the world", and whilst it is undoubtedly the best audio processor I have ever personally heard, I find little niggles like the down sampling of 192Khz sources, or its lack of ability to handle DSD streams from a suitable SACD player detract from that aim.
Leaving the subjective conversation aside (hopefully permanently) as to whether there are audible differences in down sampling or DSD to PCM conversion, as a customer, if I have purchased media with a 192Khz sampling rate, or a bunch of SACD's, I want them to be played back to their fullest possible potential given that I have "best audio processor in the world", including maintaining any necessary EQ processing to combat my in room response, not have to choose one or the other.
If what Carl says it correct (and in support of Nick, I have also been told that 192KHz Dirac processing is on the road map to be implemented), and there is no prospect for the RS20i to be upgrade to support 192Khz processing, then that is very sad to hear in my opinion.
One quick question for Carl though, assuming Dirac could be implemented on the RS20i to process at 192Khz, would it not be possible to maintain that sampling rate if the other EQ filters (PEQ etc) were not engaged. i.e. can Datasat simply change the firmware such that the those EQ stages can be bypassed, thus removing the need to down sample, or is that processing path hard wired into the RS20i making the down sampling unavoidable if 'any' processing is engaged?
