I have the KEF egg surround speakers and the YAMAHA DSP-AX620 amp. When i need detailed sound out of the left or right speakers it sounds very echoey as if in a cave! Examples are people who are meant to be in the same room but are just off camera - when they talk it sounds as if they are miles away in a tunnel! The shot can pan across to that actor and they are right next to the camera! Other examples are music tracks that may start in the centre speaker but then move to the side speakers to allow the dialogue to come in. When the music shifts it goes from sounding clear and full to sounding like it's being played in Wembley Stadium! Does anyone else have this problem and if so any solutions?? My amp settings are on Enhanced (for Dolby or DTS depending on DVD).
