I must say that when i was looking at the type x's the guy was playing them with an alpine amp on the highs and lowes. Then he switched to the mtx and there was a big differnce. I never would have thought that an amp would make that much of a difference but i was blown away. The alpine was so much cleaner. There was no overhang of the notes. Anyways I would think the premier stuff would be pretty good. If I was gonna go with pioneer it would have to be the premier line although can't say from first hand knowledge.
