I am considering doing this as it looks like the biggest bang for the buck approach. My first choice is here:http://www.analog.com/en/prod/0,,761_796_AD1853%2C00.html
The eval board is $170.00 and is a complete DAC from SPDIF in to line out. All that is needed is a 15V raw DC supply.
Anyone here done something similar? just curious.
Thanks,
Rob
