?

Hi, I want to set up a new 2.0 stereo sound system for music listening, the problem is my favourite source is FLAC files, do you have any recommend with my $600-$800 budget (amp, speakers, dac..)? I consider buying a Onkyo TX-616, built-in USB with FLAC support, then turn it to stereo 2ch, is it possible? I am a newbie, any recommendation is really appreciated.

Thanks!
