Wow, what a can of worms you've opened with that line of questioning. You need to bust out the popcorn and watch out for the debate that is sure to come. All properly designed
amps will sound the same if used within their rated specs. There is no such thing as "audiophile" amps. There is only consumer and pro amps. The difference lies in the design goals. Consumer amps are designed to run without a fan (usually), are subjectively pleasing to the eye and have remote turn on functionality. Pro amps are designed to be efficient, rugged and cost effective. An amplifiers job is to do just that, amplify the signal it receives. No more, no less. If it does anything to the sound it is now a sound processor.
That being said, some amplifiers can and do add a sound signature to them. For this exercise let's ignore those as that's not what an amplifier should be doing. Assuming we are comparing properly designed pro and consumer amps, they will sound the same within their rated specs. If you can live with the looks of pro amps I would highly recommend them for even more cost savings. Fan noise can be mitigated by simple replacements with quieter fans. I have a Behringer EPX4000 that is dead silent after my fan replacement. Don't judge an amp based solely on it's weight either. Heavy can mean that is a class A, B, A/B or H amp. Class D amps are very light and can put out enormous amount of power. My LG clone is ~28lbs IIRC and is rated to 14kW. My former Emotiva XPA-2 weighed in at 72lbs and is rated at 1kW.
So after much babbling on my part, the short answer to your question is no, an "audiophile" amp will not get you there. I don't have any experience with Carvin, but I can tell you the Crown and QCS amps are very good. If you get one with enough power that is all you need. Heck, you can even get a Behringer EP4000 for about three bills and be done with it. It has more power than the XPR-2. You just don't get the nifty remote power on via 12V triggers that the Emotiva will offer.
You have to ask yourself, what exactly are you looking for. Are you happy with the sound quality and just want it louder? If so, just get a decent amp that fits your requirement and don't get into paying gobs of money into power you won't use. Do you want better quality sound? If so, you would have to look at what you have or don't have and address that. A higher powered amp may help if you say your receiver is clipping, but it won't make a huge improvement. It will only allow you to play a little louder before it begins to distort. You have to know if the amp is you limiter or if it's you speaker though. If you speaker itself is at it's limit due to mechanical or thermal limits then no amount of additional power can fix that.
That Elite SC-67 is no slouch. Where is it in the sound that you want to improve? MCACC does not do any EQing of the sub channels. Are you crossing your mains over to the subs? That should take a huge load off the demands of the speakers and receiver amps. The QSC sub you have has a very narrow frequency band (48Hz - 134Hz -6dB/+6dB) that means the F3 is somewhere north of 50Hz. Is it possible you are turning up the volume to try to fill in the lower octaves that your sub can't reproduce? Ok, I'll stop babbling for now.
