Thanks for your responses everybody. Some really good options in there.
I hadn't thought of the Traid One as an option, mainly due to the amplification, but it does make a lot of sense. It does have a great DAC and will work perfectly, hand in hand with C4, obviously. Much better option than a mostly redundant AVR.
I'll recommend it to him today.
Thanks again. :)
