That's exactly what everyone's concern is. I stumbled on this too. A good friend has it. Does not hear it. 20 people on the whatsapp thread have it. Non so far say they hear it. Hear, as in it drawing down their sound. Those that are a little better funded and feel their system is beyond the Mac Mini version step up to the Adio or higher. Most every one of those people sell their Playback design or some such DAC as the internal one is better in the Adio and higher. So now your at a server to the Adio to your preamp. Lots of people have sold their MSB Select.As I understand, beingz that the Baach is Mac only software, you would have to run it through a Mac mini and then the babyface and then your dac.
So, a much more complicated system with many more connections that might have sonic costs involved.
The Baach plus ORC is interesting, but adding more interfaces and conversions is a bridge too far for me.
If they ever produce a Windows version I might want to check it out.
If you are able to hear the BACCH4MAC the fact that the phase, timing, room impulse and frequency are far more correct overshadow any perceived additional interface. Sub integration is far easier too. You basically turn off the controls on the sub and let the software in the BACCH handle it. The software is light years ahead of anything that was made in the past.
When I get my new house and room built out, I will get one. I held off in the past as I have a business that benefits 0 by having it. And I knew this move was coming and wanted to keep my life simple in anticipation of the move. I have been selling off all I can that I don't use now.
