I'd bring the speakers to your friend's house too and see if the problem exists. If it doesn't you may be having a speaker cable or dirty connection problem somewhere in the chain. The fact that you re-connected your amp to your speakers and the problem decreased seems to point to some corrosion/dirt in the connnection. Maybe try some connection cleaner and see if that helps?
The high range on my speakers are harsh...
I have noticed since I set up my system that the high range is rather tinny and crackles at times. I have tried tuning the treble and bass on my amplifier, but the problem still persists.
I have a Rotel RA-972 set up to two Paradigm v6 Mini Monitors. The quality of this problem differs on the inputs that I am using at any given time. Playing music from my laptop through a RCA to stereo input is the worst, however the audio quality when watching movies or television (connection RCA to RCA) is problematic as well. All my speakers are connected by 16 gauge speaker wire with 24k banana plugs.
If anyone has any ideas how I can optimize my system, it would be much appreciated.
