I tried satellite radio for a few years. The playlists are not very "Deep" as you guys say. For one example, I know no one who likes Kansas, unless they have albums. Just how many times can you only hear Dust in the Wind and Left Overture without learning to hate them? There are way too many really good, complete albums by many rock groups to give up, but jazz and classical have multitudes of varying music. Of course, you need tone controls for all the above, or like me, matching amp and preamp pairs to keep things in phase. Yes, I do measure my sub driver depth to align them with my 803's.
