Hello,
I was (until quite recently) in the throws of setting up pc audio and have been spending the last few evenings testing playback software. I wanted something that would match the delivery of my reference CD player and i have found "Album Player 2.9.5b" capable of doing the job.
There was an musical difference with it and other players at the headphone stage of testing. At speaker output - the test tracks were a joy to listen to.

I bear no relation to the software
Hope this helps.
