Arc audio xdi 600.4 or alpine pdx-f6

I'm trying to decide which amp to go with and the xdi 600.4 and the pdx-f6 look almost identical except the alpine cost a couple hundred more.. Anyone heard both of these, which is cleaner? I'll be runnin hertz hsk 165 components up from and hertz hcx 165 coaxial in the rear with the amp I choose.. I do have an old American made precision power pc4100 that's 100x4 but I'm looking to free up space and that precision power is huge... Also will either of the two amps I meantioned even compare to my precision power amp? Thanks for any input

Get the one that makes the most power. You won't be able to hear the difference otherwise.

They both put out 150x4.. I think I'll prolly go with the arc..I've heard a lot of good things about arc and kinda wanna see what the Robert Zeff hype is about:nerd: the alpine is a cpl hundred more than the arc unless I wanna get it from unauthorized dealer then it's 100 cheaper which I don't think I wanna do that.. Also the arc is just a tad smaller in size

Arc makes great stuff, but i must say the alpine is no slouch. they are both much better sounding than the cheaper class D full range. AKA class T.
