Wyred : Unfortunately, Ayre Acoustics does not list an email address on their web site. They prefer to use the phone for customer service. I suggest you call them at 1.303.442.7300 x223. See
http://www.ayre.com/contact.htm
If you cannot call Ayre Acoustics, you could mail them and ask your question. I am a little confused since both Countingbackwards and I have explained how to identify an "evolution" model of the Ayre AX-7e. In my opinion, if you are going to buy the AX-7 amp, you should buy the "evolution" AX-7e model since it is much better sounding than the older AX-7 version.
As noted above, all evolution AX-7e models have the word "evolution" written in gold lettering under the Ayre logo on the front front panel. I checked my AX-7e and it does have the words "evolution " on the left front side of the amplifier as described above by Countingbackwards.
