Do a specific search on the Revo.
Thanks, Semi.
I did find, among other things, some posts showing that the analog circuits on the Revo is basically as good as that of a decent receiver, with respect to the S/N and other actual measurements. Although most of the people who do these elaborate comparisons seem to carefully build their own HTPC (so no guarantee for an easy plug-and-play), I guess my prejudice has largely been eliminated.
I also learned that the sound quality and measured specs can wildly vary among different brands of cards! They are talking about hugely audible differences there.
Cheers!
