Yeah LOL people looking for the best audio quality don't know what they are doing if they are playing their music on their 8.1 setup. Unless you are talking about movie tracks just about all master audio is recorded for a regular stereo setup. 2/2.1. The algorithms that are used to generate the extra channels to play a 2 channel recording on a 2+ channel setup will likely distort the soundscape and at the VERY best do nothing. FAR better to get a quality 2.1 setup. This is just for music of course.
also lol@ people with shitty computer speakers trying to make their music sound better.
If you want to be able to hear a real difference between lossy and lossless audio, you're going to need a better setup other than your standard logitech getup.
edit: and its pretty amazing when you can pick out 2, 3 or more different 'threads' in the music you're listening too. and pretty eye opening when you realize that song you thought was good is actually crappy.
