Hi Stringreen,
Great system! I love Ayre gear! I have the MX-R's and at one time had the Ayre K5xe MP. I have also listened to the 5A's extensively and they are wonderful.
I have a question for you. It looks like you are using stock power cables for your Ayre equipment. Have you every considered upgrading your power cables? I did an A/B comparison of stock cables versus Shunyata Python CX cables (in my system) and there was a significant difference. Better bass and you could pick up more subtleties of voice and music. I believe that Shunyata is going to be coming out with new power cables so you could possibly get a nice deal on audiogon in the coming months.
