I've been using Winamp to stream flac files for a long time now. I'm using the Chaintek (sp?) 710 sound card hooked up to my Panny receiver using optical digital out. The chaintek can be configured to 44.1, not 48k like most soundcards.

IMO Winamp is so much better because it's easier to configure everything how you want it. I have all the winamp functions programmed into my receiver remote so I have one remote to control everything. I never have to touch the computer to choose and listen to an album, see the album artwork, read the lyrics, watch a visualization etc.

Here are some screen shots of Winamp hooked up to my tv.
