well, I am still hunting that noise and have now found it, I just need to know how to get rid of it. I found that when only one amp is installed, I am fine. When I put the other one in, the noise starts. However, the noise is not just present in the speakers, when I put my ear to the powersupply of the Xtant 603x (which has RCA's from it's lineouts going to the amp for the tweets) there is the same noise, only it is coming from a transistor or a transformer. The noise goes away when the other amp is unplugged. Am I looking at having to send the amp in?

I have put in a couple of xtants that made a wierd noise from the torroid. The noise was sort of like a hum. Xtant technical dept. told me to paint the torroid with finger nail polish, and it worked. It seems the torroids aren't wound tight enough and the energy flowing trough them made them vibrate/ring. Im not sure if this is your problem, but I just thought I would share this, maybe it will help you.
PS When the amp is making the noise, push gently on the windings on the torroid, and see if it goes away, if it does, then coat it with something (one guy used silicone, looked bad, but it worked)

Damn this is getting wierd. The techies at Xtant are stumped. Pressing the toroids did nothing. Here are the particulars: the noise in the power supply only starts when I ground the other amp. How could the other amp be modulating the power supply like that? Audiophyle, could this be some complex ground loop? They do this when grounded to the same point, and even when I hook them up to a wire that I ran to the ground on the battery they do it. I am getting extremely frustrated, I have not been able to listen to my system for a week.
