HELP with MAC MINI and PS DIgital III DAC

Meiwan raises a good point/possibility...Itunes cannot handle FLAC...I use Max to convert from FLAC to AppleLossless, and it's free and easy to use. Once you convert to Alossless, ITUNES will see and process it just like other music in your library....

AMARRA, while great stuff, is only a front end...and works with ITUNES

HOWEVER, you really need to tell us what you mean by "can't play"

Without knowing where you are stuck...it's hard to for us to tell and help you.

K. Thanks to all- using USB cable to DAC. Thinking that is problem. High res transfer not happening. Amarra software says can not accept file , then shows 9600 not ok? Read somewhere need to use digital link instead of USB ? But why Rad shack working fine ? Also,PS DAC "upsamples"? So is it not set up to "just play" hi res?

Oh, and Amarra has built in Flac converter thingy to make new iTunes readable files. Hav done this. They will play thru iTunes only. Not thru Amarra. And play at 42(?) vs 96(?) that I prefer and had BEfoRe upgrade?!?

Upsampling and processing and outputting a high res signal are two entirely different things....I really don't think you're going to get high res from the USB port...however, as far as I know the optical will support it.

Good Luck.

Wrap up- seems the ps DAC isn't the right tool for my needs. Wanting to play native hi res files. Thus, unit is for upsampleing files. Plus I've learned standard USB does not support hi res file transfer. So... Back to drawing board and more homework. Gatta' love this hobby! Again-thanks to all who took time/effort to share....(at least I think I got what's goin' on)
