I bought the Musiland after you praised it in a post a few weeks ago. I have been using mostly ASIO4All v2 with J River which sounds great. It sounds substantially better than the Lynx coax SPDIF using the Lynx ASIO driver, which surprized me. Is that the KS you recommend?
I may try the battery mod. Does it matter whether the + or - goes to ground? Does this make a dramatic improvement? Since I am primarily using toslink, I probably will not change the bnc/phono sockets.
The receiver chip in my DAC is a Wolfson wm8804. Maybe that makes a positive difference.

No, it is kernel streaming mode in windows xp. Foobar supports it but I have never used J River. Have a look under OUTPUT and see if this is available.
It is not possible to find a tight 5V supply using batteries. Li is too expensive and requires voltage regulation. Li-ion likewise for voltage. You may be able to use akaline at 1.65V in series but I don't suppose an AA cell setup will last that long. Still it may be worth trying. Bypass with a good 470 to 1000u cap. and DO NOT connect polarity wrongly. I use a ALW Jung type regulator.
You could always go directly to 3.3V supplied from a battery, lift the 3.3V leg output pin of the 3.3 V regulator & feed the battery 3.3V to this output pad! This 3.3V then feeds to a 1.2V regulator.
The local regulators are spec'ed at 1.3V maximum dropout voltage. So the minimum input voltage is 3.3+1.3=4.6V. I'll say 4 nimh cells should work well. (4.8-5V). I think the device consumes 200-300 mA, mostly the USB controller, so a 2500mah cell should last many hours.
I am done with rechargeable; they are nothing but trouble over longer term. They too can be noisy as well.
