Hey, since I just got my PLX 2402, I need a preamp for it. I've seen alot of preamps in this range, and don't know much about them. What I would really like is a Navigator, but those seem to be out of my range. What are good preamps in this price range? I will be using a Cirrus 5, 55-01, through an Eden 4x10. Thanks, Scott D.
