I have finally had enough..its driving me wild. Firstly, here is my equipment: Yamaha RX496 reciever Toshiba SD2960 dvd player Dali Concept Centre speaker Paradigm Monitor speakers Im using a Crest Xstream optical cable from DVD to amp, and good quality speaker cable, all new. Now here is my issue. I have distortion on my centre channel. When someone tends to speak up a bit it distorts. I have had this for a while and use to think it was just the dvd. I was using a crap SOny centre that did this. THen i bought the Dali speaker, and it still does it. Has anyone an idea what it could be? I have dynamic range to max,good cable. Its so fustrating, i cant help notice it all the time now! WOuld appreciate your ideas!
