Hello,
Yes, I've been working with the DAC-100m since CES. Actually I should amend that. I've had the hardware since CES, but the drivers arrived later.
It is well built, and once I managed to get the system to recognize the hardware, which required a couple of install and uninstall cycles, the unit worked fine.
I've tested it with a variety of music, as well as both version of 2 and 3 of AudioGate, and once the drivers loaded properly I could use it with other software.
I'm not done with my testing, so will report later, and will publish a full review on www.maceditionradio.com when complete.
But.. so far, it is a very good sounding system, and the test that Korg uses to demonstrate with MP3s is very interesting. Check out their video on YouTube about that.
It is an interesting design, and the ability to natively work with DSD files is fascinating, and has few peers. The build quality is very good, solid, lovely matte finish, and a firm feel to the volume controls.
I'm hoping to record my own DSDs with a Korg recorder and at the same time use a Zoom at 24/96 to compare the quality, which will undoubtably reveal different microphones, electronics, etc.. but I'm hoping to see if I can hear the "DSD" analog sound quality that so many folks claim for DSD. That coupled with the DAC-100m as the DAC and headphone amplifier should prove to be an interesting, if not too scientifically rigorous experiment.
I think that if you are really into DSDs, then the Korg should be on your list to audition. Personally while the big brother of this unit has balanced XLR's, I know of precious few folks who actually use them. At least in my circle!
I'm really interested in other folks thoughts on this gear.
