Recommendation on power amp

Lol don better is my local ayre dealer.

You say you are presently using a pair of Parasound Halo   JC1's.  Are you using these as monoblocks?  Read the specs and this is a really powerful amplifier.  Why would you need anything else?

Ayre + Blades

Now that they have severs hundred hours on them and are now driven by Ayre MX-R Twenty monoblock amps they are, in a word, awesome!!

I am biased. I think the blades sound great with almost any amp.

Newtoncr, have you tried calling Ayre's corporate offices?  I own an Ayre K-5xe pre-amp, your CD player and a QSB-9 DSD DAC.  Unfortunately, not the MX-R Twenty amps nor your KEF speakers.  

My point is that Ayre's customer support has been excellent in my experience.  They have been helpful in answering several questions and in making some recommendations.  Perhaps they can help you get the amps home for a test.  I would not hesitate to advise them of the response you got from your local dealer.  I agree wholeheartedly with those who have noted that your dealer should be happy to arrange a home demo, particularly given your past purchase of Ayre equipment.
