I’ve had some issues with a grainy sound very recently but it’s got much worse in the last couple of days, I sometimes think it’s me though .
This morning I decided to power down the system and clean [1] all the cable connections and see how it went.
Well I was greeted with horrible distortion that sounded like fluff on the stylus, sibilance and a general weird almost echoey sound. The 250 was supposed to be Naim serviced in 2015 but I’ve dropped it off with Darran @ Class A so I’ll find out soon enough.
