I like listening to high quality audio. The problem with listening to high quality audio has traditionally been that a person must play vinyl records, which are impractical store or one must buy high end digital files. Buying high end digital files has traditionally been a pain also,because you need to go to lots of different niche websites. Once you go to these niche websites you need to figure out which file type to download, get a third party program to download them and then use another program to play them.
I don't care about any of this technical stuff. I just want the music to sound good and I want an easy to use system like itunes, where I press one button and the music downloads and starts playing.
ponomusic is the best solution I've found. It's designed by Neil Young. With this service you get physical device that operates like a ipod and also a store like itunes.
Here's a chart comparing audio quality:

I've been listening to this device and audio downloads from the store for several weeks and I notice a significant quality improvement over CD quality. And of course the quality improvement is even much better than MP3. It makes me happier. I "feel" the music instead of just listening to the music.
A downside with this service is that the high res catalogue is limited right now.
