Hi KEW,
Thank you for the link and for taking the time to listen to the YouTube link and comparing with other sources. Typically, I use Amazon Music and it sounds clearer than the YouTube example.
I listened to it a few more times over the weekend and you're right, it does sound kind of synthesized. With regard to headphones, I am using a $20 pair from monoprice that I picked up a few years ago because CNET said they were good,
http://www.cnet.com/news/how-good-can-21-59-headphones-be/. They headphones sound decent to me, but I'm no expert, and the bass sort of masks the synthesized part of the "sound" lyric.
Again, I appreciate you taking the time to listen to it yourself. I have stopped scrutinizing that particular song and am now trying to learn more about Foobar2000, wasapi, and how to send music to my receiver, from my HTPC, without Windows 7 altering it in any way. I am still researching, but if you have any links or advice with regard to bitstreaming stereo then I am all ears. Thank you.
