Play FLAC Pioneer VSX-60, Yamaha RX-A720

I'm trying to decide between 2 receivers. Those two are the finalists. I want to be able to play FLAC Files through my receiver on my 7.1 system.

My computers runs Windows 7 64 bit and I use Winamp to play my FLAC on my computer. I have many large concert FLAC files. Is there a way to play them through those 2 receivers? I have an older Xbox 360 and am getting the Panasonic PC-P50GT50 TV as well if that matters.

Are there other components that I need to make this work? Or can I somehow stream the files directly to one(or either) of those receivers easily. I read somewhere that for the Yamaha I need a certified DLNA media server that supports FLAC to make it work. I have no idea what that really means. I'm not particularly savvy with these things and if it could be explained how I can make this work in a "beginner's" language that would be great. I want to make this as simple as possible.

Thanks, I really appreciate the reply.

Since option 3 is the one that would be most convenient for flac playback my biggest question is what can I use as a DLNA server for flac. Is there a program out there I cam just download(if so, whati don't know how to find one) or do I need some kind of hardware device.

Again, I'm trying to research but Im having trouble with really gettingy head around what I really need.

Again, thanks for the information. That really helps. That gives me a lot to go on and I'll do some more digging into that to see what is going to work for me.
