Got mine on Saturday, don't have DVD-Audio yet, but the 5.1 mixes are really good especially for something free. My favorites are Contemplation and Big Phat Band. The placement of the sounds in the rear are plenty but not artificial IMHO, I did find Summertime Mungo Jerry to be a bit much.
I got this disk last week, forgot about it actualy. I thought some of the songs where pretty awsome sounding on my system. I really liked the sound mix of Big Phat Band. Also thought the Swan Lake song sounded solid as well.
