I'm glad to hear some people tend to experience this problem, I believe and respect others do not hear it. The issue is I know personally I experience total loss of bloom, bass, spl or energizing of the room or what ever you would like to call it. All cables are many years old and fully broken in, ranging from JPS, Acoustic Zen, XLO Sig. and Harmonic Technology, so solid core, silver and copper. One thing mentioned is cleaning connections is something I haven't done in a year or so. If some believe removing cables need time to recover sonicly how can you judge adding or subtracting cables to improve things when the benefits or down falls take a few days to hear. My main system I rarely change things. Maybe it's best to set things up best you can and leave it alone and listen to music, it sounds good now
