I have an intel imac and run optical out > glass toslink > dac (grace 902) > amp > speakers
I am playing almost everything in either Itunes or Play.
The limits on my machine are 24/96, but i downsample all my 24 bit stuff to 24/44.1
For my cheaper bedroom setup i use a cheapo dac (DAC AH) from here:
http://www.pacificvalve.us/index.htmlFor 170.00 it doesn't sound anything like the Grace but it sounds very nice
for its price point.
For your deal, you can go analog out (rca's) from a dac right into one of your
analog inputs on your receiver.
