Wyred,
If you believe that the amplifier of interest is an Ayre AX-7E but it does not show the faint gold "Evolution" label on the front panel, then it is still possible that your unit is an "E" version that has been upgraded from an AX-7. To its credit, Ayre Acoustics offered this upgrade at nominal costs to existing owners. As a result, there are likely quite a few of these units around, and they should be equivalent to the units shipped originally as AX-7E's.
As stated above, a call to Ayre tech support with the serial number of your unit will give you a definitive answer. Optionally contact an Ayre distributor in your country and he might be able to assist you.
