I should have labeled it Speakers?

My system..... Vandersteen 5A, all Ayre preamp, amp, CD player     I thought someone might have a suggestion for noise in my system....sounds like a resonance in the upper mid/highs from the left. Noise remains if CD or Vinyl.  I tapped around the room with a big spoon to hear if anything was vibrating...none.  Changed the left/right cables..remained in the left.  I use a separate headphone amp with earphones...don't hear the noise.  Took out the tweeter and mid of left speaker and sent them to Vandersteen...good.  I sent the amp back to Ayre (150 lbs) ....fine. I checked that the cones under the speakers are tight. Richard Vandersteen, and Dealer Audio Connection took lots of time with me ....couldn't suggest anything I hadn't tried.  Anytime I listen to the system I listen for the noise and when the frequencies are "right" I hear it...very annoying.

String, if it was me I think I would have just picked up the left speaker without disconnecting anything and moved it to where the right was and vice versa.

If the noise persist in the left you know its not the speaker, cable, amp or preamp, just the room.

I've had to do this to determine that a noticeable speaker volume difference was only the result of its placement in the room.

I hate buzzes. Truly nasty beasties.
Did you have the Preamp checked?
I, too, own Ayre with my Vandy's, and am surprised you should have such issues.
You seem to have ruled out interconnects, but have you tried changing the power cables?

First thing I thought was the room. +1 on what Douglas said.

Swapping speakers is a good idea,  but to hear the correct sound of the anomaly you would have to break them and the wires in again for at least 200 hours.  
Heheheh...    ;)
