cyrus

I currently have some ordinary cheap xlr cables tied to my Cyrus phono pre amplifier and McIntosh 7200 Amplifier, will a high quality xlr cable improve the sound?

Dear all, I have a Cyrus 7 with this problem: when I turn it to standby mode there is a ‘pop’ noise on speakers at quite high volume. When I switch between channels there is also similar noise but at much lower volume. And when the source is off (in my case TV) there is some time similar noise...
