i have a brand new CLASSE CAP 151 integ. amp. The amp works like a dream but on shutdown i get a "whistle" in first one speaker, then the other. Sound occurs after amp is powered off. ANY THOUGHTS?
It's definitely the amp (minor problem). I had the samething happen to me some years back with a Classe' DR-9 with the whistling right after shiut down. They replaced the relay circuit and good as new.
