Have you used the AK100 II as a USB DAC on a Mac? The manual says Windows only, but the website says Windows/OS X. So, which is it?
MQS server - if you look at AK's website, they only have it listed for the AK240. I haven't checked out my AK 120 II fully yet, but someone said that there's a copy of the MQS software on the unit itself, and others have said you can use the AK24) MQS on the website without issue. Both are probably true (I say probably cos I haven't tested it myself personally yet).
It would be nice for the AK unit to support OS X's finder natively, rather than have to use Android transfer software. AK doesn't clearly state this on the unit's dedicated page (they might mention it in a FAQ, but my point is that it's deeply hidden away from the ordinary person, browsing their site). It should be clearly stated on the product page.
As an aside, I had a bunch of pre sales questions, that due to the lack of contact details on AK's page (it seems that they don't want to talk to their customers), I directed at the Aussie distributor - that was last Sunday...no reply at all.
They give a stingy 1 year warranty in Australia (I've heard longer warranty periods in other countries, but not confirmed), which is completely unacceptable given the price and implied pedigree of the brand. If the unit fails in the first 3 years, I'll certainly be challenging that warranty (which I can do under Australian consumer laws I might add).
The unit is great sounding, but AK/iRiver's support leaves a hella lot to be desired.
Just my honest 2c worth. I guess as consumers we're being brainwashed into expecting crap support or product misinformation as the norm. Well, those who accept that sort of treatment from manufacturers, not this lad.
