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.

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...    ;)

Wait, you have swapped the speakers entirely, and the noise remains in the same place??

Thanks for all the considerations. It was suggested to me that I exchange a different speaker for the left Vandersteen as a test. When I exchanged one of my 5.1speakers that are in a different room..NHT, Vandersteen got pissed off at me for telling him the NHT didn’t have that noise. It seems that Doug might indeed have an answer...The NHT speaker was to the right of the Vandersteen and would probably not have suffered the Vandy problem being in a different place. Tomorrow I’ll post pictures of the room...16 foot ceiling. I thought that would be a good thing, but it isn’t. Follow this thread if interested.
