I just want some opinions of other people on the Rainbow iPaul 4.300. I want to get rid of my Alpine PDX2.150 and get a 4 channel. I have a set of Rainbow SLC 265.25 NG's up front and 2 Phoenix GOLD RSD 65 C's in the rears (woofers only no tweets or x-overs) So what do you guys think of the iPaul? Is it a pretty good amp? Does it have good sq? My friend has the Arc Audio class H (cant remember model) and he swears by it and the high damping factor. Does damping factor have a huge impact on the sound quality?
