Have to disagree with a couple of the posters above, the Primare I30 and its predecessor the A.30.1 , offer higher resolution and a much more muscular sound than the 2010. Class A preamp section, dual mono power section, fully balanced design. It's a step up on the criteria you listed. Haven't heard the Ayre, but depending on your speakers, I should imagine it will trade big hits with the Primare, being a fully discrete, zero-feedback design, but with less rated power and higher cost, of course.
Ayre vs Primare
I'm still looking for a new integrated amp. I currently have an Exposure 2010S2 driving Spendor A6's with a Sony 5400ES SACD player as my source. I have moved my system from a large living room downstairs to a smaller room upstairs so there is no longer a need for a high powered amp. My two candidates are the Ayre AX-7e and the Primare I30. Deep controlled bass and extended highs, while nice to have, are not as important to me as a natural, transparent musical presentation. Another reason these two amps are on my short list is because they have balanced inputs. Also, as a long shot I might add the NAD M3 to my list. I've searched the net, but can't find a direct comparison between the Ayre and the Primare.
