QSC MX3000a POWER AMPLIFIER VS. CROWN REFERENCE I STUDIO POWER AMPLIFIER

[BRANDONH]

I will be using it for home audio.
I just could not find any reviews on the MX3000a but it had the power rating I was looking for and lower price.
I have custom made pro sound speakers and I want more head room than I have now.
I am using a ATI AT15004 bridged to 450 watts per channel and It does a good job but my speakers are large and power hungry. I went to Crown and read up on the K-2 but it is only 50 watts per channel more than I have now. You have helped me to confirm that the Crown Reference I is the way I should go. I have read many reviews on the Reference One and all but one were good. (one guy said that is should be used in the stuidio only and not home) and some stated that it was a bit bright sounding but tamed down after burn in and the fan was somewhat noisy but did not come on until it was under heavy a load. And they said that it requires a special wall plug with seperate 30amp wiring and not to use the adapter it comes with.
I have a very discriminating ear so I will have to save up more money and go with the reference series after all.
Thanks for your help if you have anything to add please do.
Have a great weekend.

p.s. Considering the ATI amp I already have and since the MX3000a is THX certified would it be better than what I have now or should I just forget about the MX altogether?
