Thanks for all the great input and discussion.
As for the expense of DSD land, I bought my MR-1 used for $150. Pretty damn good. True, I can't edit in DSD, but I can export to 24-bit/192 kHz for editing.
I don't plan to record concerts, symphonies, jam sessions, barking beetles, or 9 hour chanting sessions. I'm not trying to burn DSD discs.
I will do short samples of industrial sound sources, e.g. car engines, electrical motors, hot water heaters, water in pipes, gas cylinders struck with a mallet, etc. etc. I will then shift the pitch and tempo radically in my DAW (LiveLite), and save as samples to use in musical compositions: engine noise as percussion, gas cylinder as harmonic tones. So my primary concern is to minimize the resampling overtones and artifacts when radically resampling the recordings.
Would love to have more input on this.
Thanks,
Craig
