I have finally locked in my speaker positioning, however everytime I listen to music I get a headache. My system sounds very bright and is actually hard to listen to for more than five minutes. What causes a system to sound so bright. I am using acoustic panels and a rotel amp which is supposed to be laid back. I know my b and w speakers have been called bright. What can I try to reduce this. As of now I am just trying to tolerate the system rather than enjoy it. Need help with this. Thanks.
