I'm starting to think that it was just a miscommunication between you and Ayre. I thought you were talking about a noise coming through the speakers, not the actual amp itself. I will say, though, that I've spoken to Michael myself a couple of times, and he does come across as a little odd. Nice, but still odd. Just to clarify, you turn the amp on and about 9 minutes later you hear a sound for a short time, and then it goes away? Aside from the sound, the amp works normally. I have 2 V-5's and don't have that problem.
Here's what you can do. Open the amp up and then turn it on. There's not a lot of clutter inside Ayre products. When you hear the sound, you should be able to locate it. It may take more than one try. Once you see where the sound is coming from, take a picture and email it to Ayre. Tell them where to look in the picture and see what they tell you.
