I was listening to my Project Essential 2 this morning and it sounds terrible. Everything is muffled and distorted and tinny. I tried an old record player that I have and the sound on that is fine. My wife mentioned she lifted the turntable the other day to clean under it (lifted it at a 50% angle) but it wasn't switched on. I've only had it since December so I'm sure the needle isn't worn. Is it?
