For what it is worth, I use that Korg MR-1000 and the recordings can be very good. Many of those Live vs Recorded demos from VMPS that John Casler has made available here were recorded at double DSD quality (5.6 Mhz).
Those two channel recordings were pure direct from mic to HD. However, they were converted to WAV 24/96 for distribution. The Main issue I have with DSD is that only very simple editing can be done without purchasing very expensive software. So, the recordings need to be spot on the money from the start. There are no second chances with anything.
Simple two channel recording can sound very good indeed when done right. What works best are the pure acoustic performances, because once a PA system is involved you end up recording the PA and not the musicians. So, I am very interested in knowing how Ric Schulz was planning to get high quality recordings using the techniques he described. I have never known them to work well with any amplified performance.
