does the mr-1000 have digital inputs?
No. What we know of as 'digital in/out' is PCM. The Korg's are DSD.
while this is true...there are DSD transports and DSD DACs out there that run proprietary digital cables.
Sony XAC9100 > STR-DA7100 for example. thats the cheapest way to do it. (at around $5k new...I think?) the next up are dCS and Meitner, but you're into the 10-20k range for a new rig there.
and then i'm sure there are digital consoles that can take a DSD signal from some outboard DSD ADC.
ohhhh, how I wish there was a way to play DSD "on the cheap".
I've even contemplated snagging one of them tascam rack mount jobies w/a fat HDD in it and using it solely for a jukebox.
I brought up this thread on rec.audio.pro, asking for the best way to listen to DSD masters. the million responses I got were useless. "convert it to redbook stupid, you can't tell the difference anyway"..was the most common (and polite) response I received.
