Congratulations and Welcome!!!

You are so right. The source material can make or break the experience. In fact with really accurate speakers like those, you unfortunately start to really notice the bad material as being bad. The good more than makes up for it though.

Not sure what kind of music you are into but pick up a copy of Dave Matthews and Tim Reynolds, Live at Radio City Music Hall. In fact I dare you. Even if the music is not your thing, your jaw will drop to the floor.
With great power comes Awesome irresponsibility.
