Sounds like that DAC is really working out for you!
Yes, it is. It is difficult to describe Wayne, but just when I
think the sound is as real as it can possibly be, the sound becomes
more real with the updates. (50% of the electronics is in the recording
venue.) Improving half of the total electronics makes a definite
improvement, as we all know when comparing components.
I have discovered fairly early in 4+ decades of research that
the recording and playback electronics are a major factor
limiting sound quality, just as speakers, room etc are.
I have been running the updates day and night for about 100 hours.
Will continue and see if any more changes occur.
