Just wondering why would you stay away from the Diamond?

Title says it all. How would a FI Q10 compare vs an Infinity Kappa Perfect 10" VQ? I'm putting this in an Infiniti G35 coupe, and I'm looking for nothing but straight SQ, I want low extension and tight very musical bass, could care less about SPL. My enclosure size is .8cu ft., and the amp will be based on which sub I get, but it will be a higher end amp such as a Focal or Diamond.

Hey guys, I'm in the process of building a system for my Infiniti G35 coupe and I'm trying to figure out which amp to get. Here's what I'm getting: Front components: Focal 165 K2P's, 100W RMS Rear Midbass/Midrange: Diamond Hex S6.0mx3 150W RMS, or Infinity Kappa 62.7i's, 75W RMS (Haven't decided if I want full range or not in the back) The amps I'm looking at are: Audison VRx 4.300 4x110W, $1300 Audison VRx 2.150 for the fronts, and run the rears off the HU 2x110W, $860 Audison LRx 4.300, 4x65W, $640 Focal 4x75W $620 Audison LRx 2.250 2x110W, $525 Diamond 6700.4 4x110W, $525 Focal 2x75W $420 I would love to get the Audison VRx 4.300 and be done with it, but it takes a large chunk out of my budget and I could spend that elsewhere. I'm trying to decide how much better the Audison's and Focal's sound vs the Diamond that puts out about 35 more watts per channel and is about 100-300 dollars cheaper depending on which amp I choose. The majority of music will be MP3s because that's what I have more of than CDs. I just don't know if more expensive and supposedly better amps will be apparent with a lower quality source, I will still listen to a good amount of CDs though. What do you guys think? Anyone that has any of these amps and wants to comment as well, that would be great. Thanks!
