McIntosh 255 vs Parasound Halo A51 vs Anthem MCA 525


Looking to replace my Yamaha MX-A5000 with one of the above 5 Channel Amplifiers. I currently have and will use the Yamaha CX-A5100 Processor. Obviously, the McIntosh is considerably more then the other two.

I currently have the following system in my home theater:

Paradigm Studio 100 V5 (Main Speakers)
Paradigm Studio CC-690 V5 (Center Channel)
Paradigm Studio 20 V5 (Surrounds Rear)
Paradigm SUB 12 (Subwoofer)

I have always felt I was buying the MX-A5000 for the convenience of fitting nicely with the system and also being able to power other zones. Ready to take a step up for sound quality in my main system and think I need more clean power to drive the Studio 100's. My room isn't great but it is what I have for now, so I know it won't sound as good as what it might in a better room...

Any advice is appreciated!

Thanks,

Phil

Of the three, go with the Parasound A51 to match with the Studios..  Having owned several Paradigm speakers and Parasound amps in different configurations, they are a near perfect match. 
Your Yamaha CX-A5100 will work just fine.  I briefly owned an AVM60 as a potential replacement for my Classe SSP800, but unfortunately was no match in sound quality so I sold it. It might be ok for folks who mostly watch movies, but I spend 90% listening to music, so sound quality is #1 priority for me.
