For serious listening, I have a system in the basement for Lps, SACD, & DVDA. Most of the time, I listen to our cds that I ripped (FLAC) to our Escient, piped through our home theater system. I have an Ipod I plug into the car for music.
The music on it is from our collection. CD collection via Columbia House, Amazon, Ebay, and various big box stores.
