Listening Impressions
Good PRAT, texture and tone. Good sound stage and imaging is icing on top. Everything matters. Youtube is great for discovering new music. FLAC is great. Don't care about format wars. As long as the performance is good and well recorded, it doesn't really matter what format it is. Off the upgrade train. Now focus on discovering new music.

Can you believe Edge sounds better than Chrome which sounds better than Firefox when playing youtube? Me neither, but that's what my ears tell me :-( Binding posts suck! Get rid of them if you can
