I have just put up a pair of Ascendo System MS SE EW with external crossover speakers from germany and am using new cables from Germany called The Master Class what I want to ask my audiophile friends, over a period of listening to the setup it has been behaving funnily,some days it sounds very good and some days the vocal goes out of center to the left some days the music seems diffused and on some days there is a bloom how do I understand why is this phenomenon taking place Can any one throw some light on this matter is it the burn in process of the cable or what possible can it be.
