I've had this thing out for 3 excursions in the last week or so. I thought I'd post my thoughts.
I'm coming from using an R9 for the last few months. I'm familiar w/the sound at all of its resolutions.
My first outing was an on stage recording, mastered in DSD and brought straight to redbook. imo, its uncanny.
my 2nd outing was not the best. also DSD mastered and processed as above. just a poor location in the venue. nothing wrong w/it. it recorded what I heard but its nothing to wow about.
my 3rd outing (last night) came out completely awesome. 3D sounding...and get this, I mastered at 16/44 (by mistake...seems it "reset" itself after my last use.)...and it is still a very solid sounding recording, despite using the decks least capabilities in A/D. So far, I like it much better than the R9, which I also was quite happy with. The Korg just sounds a little more natural, things really image better w/the DSD resolution. Maybe its my psyche affect, convincing myself that this $700 shiny thing really is an upgrade over the deck that I enjoyed (and costs 1/2 as much). I'm going to be doing some head to heads with them. I do honestly think it sounds yards better...but this is initial work thus far. I've got a few more shows coming up. some big, some small ...some tight, some far field. We'll see what she has in her.
:-)
as I think i mentioned previously, I'm powering it with a power runner PR2-E which outputs amperage in the double digits at 5v. I have no idea how long this will power it, but I can foresee that I'm safe for my power requirements (which seldom go beyond 5 hours).
its easy to use. fires up super fast and is ready to roll in 2 seconds, give or take 1.
while its rolling, you can go into the menu and adjust levels. Everything seems to be very intuitive. Getting the files off of the unit w/the USB cable (the only option) is a bit strange as you have to tell the deck that its in USB mode, and then tell it that your finished so you can uplug it safely. not very USB like, imo. I"m used to just yankin' cables. But since they (korg) went to the trouble of adding this to the menu and a big warning on the screen when set...I will respect that.
Playback sounds very good to me, but I have not plugged it into my big system. the DSD>FLACs i've made sound better than many of the recent 24bit recordings iv'e made.
No troubles w/the software or the hardware thus far. everything just works.
