Never happened to me .
However, too many infos are missing. Have you installed the asio plug in ? Do you need dsd playback, (so that you should first congigure foobar with the relevant plugs ?
Anyway, the way to go in these cases, is to delete and then make a new clean Foobar installation. It doesn't take more than 5 minutes ...
All in all, up yo now I've found Marantz's drivers very stable with no problems at all. It is something that you 're doing wrong ...
edit : I didn't notice your latest posts ...try to change the usb cable ... hope yours is not longer than 6 feet ...
Yea, it's with every application: video/sound through browser, media players, etc. not just Foobar. I reinstalled the Marantz driver; no help. I'm going to change the USB cable, but it's the same one that worked with my DacMagic so I don't know why it would be the issue now.
Really want to get this to work properly because I think it's just a computer problem and returning and replacing the HD DAC will not solve it.
EDIT: Guys, please don't hurt me...it was the USB cord!!!
In detail, I had the old USB cord hooked upped to a USB hub (a cheapo one at that). NO idea why that was fine for the DacMagic's data stream, but it just isn't fast enough in data transfer for the Marantz (playing Redbook and not "hi res" files too).
So, put the USB cord right into the back of the computer USB out (I have a lot of devices hooked up to the computer and only 4 direct USB outs, hence the hub) and poof! cut out due to lack of steady data flow gone! Duh!!
(In my defense: 11 hour work day on 3 1/2 - 4 hours of sleep...the 8th long work day in a row...damn quarterly paper work).
So thanks to Spiro for the tip (I was about to check that out, but really didn't think it was the factor...hell, I thought the DacMagic was directly hooked into the computer and I just unhooked the USB from the DacMagic and put it right into the Marantz).
Now to go rediscover my thousands of albums...
Briefly the SQ I find to be pretty neutral. The horrid congestion/lack of air I had with the M-Stage (original stock) is gone; this set up is definitely more open and musical. I've got the gain on Med with the T1's. Plenty of power; the 12:00 position will blow my ears off with pretty much any genre.
I even find this thing kind of "dry"; not hearing a lot of warmth, which is kind of what I prefer (neutral, but not veiled or overly muddy/warm nor too cold or clinical). I think it's more of a "natural" sound than anything else; need a lot more listening with a lot of genres though. There is some sibilance in the treble but nothing that bugs me. Seems to be a good all-rounder: I've thrown rock, pop, jazz and classical at it so far and it sounds great with all.
Off tomorrow; see how long I can stay awake with my new toy.
