Looking for a used $500-$700 amp to warm up sound


I am looking for suggestions for a used 3ch amp (150-220wpc) to power a Paradigm cc-470 center and a pair of Paradigm Studio 40.3 used as mains. I am looking to spend $500-$700 on a new or used amp. The Paradigm's tweeters are a little bright for me so I am looking for an amp that will warm things up a bit. I am using a Denon AVR-3802 for my pre-amp and to power the other channels. I am using Signal Cable's Analog 2 ICs and shotgun bi-wire speaker cables. I tried a B&K ST-3140 amp (3*140watts) that sounded great but didn't have enough power to drive the speakers as loud as I like. I am considering an Anthem MCA-3 or MCA-3 mkII amp. Does anyone have any experience with the newer and older versions of the MCA-3 amp? Or any other suggestions?
Thanks.

Honestly my friend maybe you should look at other speakers.. if not happy with the treble of the Paradigms. I say again why waste the money trying to change the characteristics of the speaker by covering it up with an amplifier? There's surely a speaker out there that will make you happy.

Good Luck!
At your price point it is practically impossible to get the sound you are expecting in a 3 amp set up. Paradigms do not necessarily sound warm anyways. They are supposed to sound accurate, that might translate into a harsher treble. The only amp designs that might suit your musical taste are Class A amps. I do not know of a class A amp with 3 channels that goes for the price you set. Another amp choice would be the McCormack and that will cost you.
