It would be balanced which is supposed to be better, but purely from an electrical point of view balanced cabling is more of an advantage on long cable runs. Some people find it sounds better though and anyway it can't hurt if you have the outputs & inputs to use them. Some balanced amps will only be able to leverage their strength if the input is balanced as well, not sure about the V200.
Audiolab completely dropped the ball, they mention it in the manual but then don't follow up on their site. The original designer of the M-DAC, John Westlake, hangs out on the Pink Fish Media board and has been providing help, and with other members, access to firmware updates and the BitPerfect test files etc. The PFM board tends to split threads after the post count reaches a certain point, so for now we're at VII: MDAC first listen (part VII) There will probably be more in the future and you can read the older ones for some interesting info as well.
You can go backwards from the latest post to find the most recent updates, but I did one summarizing the links and AFAIK there hasn't been a major update yet (the final 1.0 firmware or the LakeWest custom one w/ dimmable display etc.) only an experimental A/B test version.
