I have too much to say using the iPad, so I'll cut my comments to the bone.
It was the worst of times it was the best of times - while I agree with the premise that the iPod -mp3 radically changed the listening habits of much of the “modern” generation, there is still a market for high-end audio gear. Methinks if you are spending in the four to five figures for a sound system one is going to listen to it attentively. I also note that there are several turntables on the market, many also reaching into the four and five figure level.
Anybody with the most modest home computer can produce their own mix disks that are as good as what are sold commercially that sound way better than the old mix tapes and it's relatively easy to up-sample even a lowly mp3 file to 24/192 resolution and you will hear the difference, even with crappy source material
