Hi, I have a hi-fi system that I am generally very happy with BUT... I find that with many CD's it seems that the left hand speaker (left channel) is slightly louder or more "busy" than the right hand speaker (right channel)!!!! Maybe it's the room shape or the bay window that is doing this? I do occassionally change the "balance" control on the pre-amp but don't like doing this because it changes the sound quality marginally. Has anyone else noticed that many CD's are biased to the left channel? What did you do about it? Also, is there a refernce "test" disc or something I could use to measure the channel levels in terms of dB's? Thanks for your help.
