I have a two of the 125's in my system, and one of them makes a weird whistling sound for a while after first turn on. It's like the amp is oscillating or something. The other one doesn't do this. Is this normal? The sound goes away after a while, but I'm concerned that this thing will eventually oscillate itself to death. thanks.

I wouldn't consider that normal. Neither of mine do it. Probably would be good to take a recording of it and then open a support ticket.

Thanks. I'll just wait for it to fail, or something like that. I have too many other things to do.

Thanks, but, I think I should try it on a house circuit that actually has a functional ground connection first, don't you think? Some idiot cut most of the ground wires in my house....

Hmmmm, it doesn't seem to make the squealing sound any more. Maybe it healed itself? We can hope. It just makes the usual hiss and noise like the other one.... That's what I get for using high sensitivity loudspeakers with these plate amps. I had no idea this would be a problem.

I've talked to other people who have used the Power ICE Class D amps and they all say that they are noisy. You should consider changing suppliers or otherwise making changes to your product if you expect those of us who want absolute quiet from our amps to use your products. Your plate amps are not suitable for high sensitivity loudspeakers, like horns or pro audio drivers, where sensitivity can be 100-115 dB. You should consider making a lower power product that uses a Class AB amp that is dead quiet. Just a suggestion.
