Well, the Mac has been in and out of the shop a couple of times. They got it back up and running without too much trouble, but as it turns out the digital audio board is done. It's funny, because all of the digital inputs work just fine except the USB audio input. Wouldn't you know, just the one that I actually want to use.
New board is $835 installed, so I hope to have it ordered in the next few days.
I'll be moving on in the speaker world too. The Magnepan's are up for sale since I have a pair of Canton Reference 1's on order.
