Sound Quality.

This is the Cowon X7 which is reputedly the best quality MP3 player on the market, outperforming even the Hifiman HE which apparently costs in the region of £550.

It arrived this morning and all I've got to do is charge it up, load my music library onto it, plug in my Shure earphones and give it a good listening to. I expect to mainly listen to it via Bluetooth headphones but the Shures should provide a more critical test.
