Thank you ar-pro,
I had already read the review you have posted as well as Julian Hirsh's AR3 review.
The probem is that the review you posted says that AR3 lower midrange was criticized to be emphasized while, on the contrary, I have listen to a low output midrange (for example, human voices were much more smaller than I am used to listen to not only with my 3as but also with other loudspeakers). Moreover, Villchur, in one of his very interesting AES interview said (if I have understood everything precisely as English is not my native language): "The most important element of a speaker performance, that, I think, really counts, although perhaps not the only element, it's the amount of power projected into the room and if the power in the bass, mid-range and treble is right, is balanced, it's going to sound good...etc" http://www.youtube.com/watch?v=O6vI1V_TChk
Hirsch's review says that the differences between AR3 and AR3a "were not hearth shaking".
After reading AR3 reviews and listening to Villchur's interview I have thought that the AR3 midrange drivers I listened to could have some issue but, as it has been the first time I listened to AR3s, I'd like to know from people who could/can compare perfect AR3 and AR3a if a "low output" midrange was a normal AR3 characteristic.
As said, english is not my native language so I'd like to know from all of you what the reviewer means saying: " AR3a sounds less DRY than Ar3" as reported in the AR3 review posted by ar-pro. I could not understand what "DRY" means in the context of sound and if it is something negative or positive. From the context I'd say that "DRY" is something negative but I'm not sure.
Thanks again for all the comments
