Hi,
I had one before. There is a review on the Stereophile site.

I can confirm what was said. The analog output is not bad but you will ned a DAC to get the most out of it. Depending on the DAC, you may miss the first seconds of a song as with my MF Trivista DAC-21. At the end of the day, I had fun with it. But since I use CD's instead of downloads, there was little benefits to keep it.
The Apple TV is something you may want to consider also.
