Thanks. But, three separate stereo rigs/DACs give a hugely inaccurate and inconvenient issue as to a single volume control. I believe the 93s internal digital volume control will throw away bits and sacrifice resolution. I suppose one could put the analog output from three stereo DACS through a Mch analog controller, such as a Parasound P7. But, I am not seeing the advantage to that. Is there an audiophile grade Mch Dac, ignoring the volume control issue.
As far as a digital controller or AVR is concerned, offhand the only one I am aware of that could handle three or four simultaneous coax connections is the very costly Meridian, which does not interest me in the least. Are there others?
So, I am not seeing the sense of either of these solutions for Mch, especially not when compared to HDMI from a 93/95 into a digital controller or analog from a 95 directly into an analog controller. For stereo, the Oppos already have an spdif coax out. How is this solution superior to that, especially audibly?
Are there multi-spdif input cards for PCs that could combine the Mch signal there? Is there PC software you can suggest that would mix them into a composite, Mch PCM file for playback (via HDMI for me)?
I am still scratching my head as to the usefulness or sense of this product. Mch output via a single USB connection looks like it would have been more useful.
My real potential interest in this product would be to effect a conversion of DSD to PCM at higher than the Oppo's standard 88k. Only a few non-Oppo players appear to to that now. Just so that you know, I am a huge fan of Mch and DSP room EQ. An Oppo-based solution that is audibly superior to straight HDMI would be worth considering.
