I am an audio engineer and wanted to point out that if it is higher quality audio you are seeking, I recommend DVD-Audio discs. These are 24-bit while CDs are 16-bit. Mathematically, DVD-Audio discs have 256 times more depth than a CD. Even a regular DVD-Video disc being played in DTS or Dolby Digital Surround is many times better audio quality than the best quality CD. Also, with DVD-Audio discs, typically, there is an option to play in 5.1 surround sound. Sometimes this is a completely new mix (not just crowd noise added to the surround speakers for instance) where you can hear things you may not have noticed or even been able to hear in the stereo mix of the same song. So, if it's quality sounding audio you want, start paying attention to the things audio engineers pay attention to. Tapes and records are often better sounding than CDs as well, not just DVDs, btw. Lower resolution recordings such as MP3s, WMAs or MP4s (AACs) can be decent sounding on earbuds but do not even compare to CD quality, much less higher quality media. Have fun.
