I was considering alternatives a few months ago. I ended up buying one of the new MacBook Pros, and I use the digital optical output directly into the G68. My songs are all Apple Lossless on an external hard drive. I still prefer the sound of my 588 CDP, but for convenience, the Mac is a great way to go. I use the iPhone with the remote app as my controller. For the price, this is hard to beat.

Good luck,
John
