While I cannot argue with any of the suggestions above, I believe there is no "universal" right answer as to what is causing the sibilence in YOUR system.
I have been chasing a sibilence problem in my system, taking the suggestion that room treatment should be the primary target. I chased my tail with treating first reflections, rear wall reflections, covering all windows, etc.
Then it dawned on me to conduct a simple troubleshooting test.....I used headphones hooked to the tape out of my ARC SP8 preamp. I figured that would take the room acoustics out of the equation. Put on a troublesome LP, and the sibilence was still there. So my problem in my system is somewhere between the turntable, cartridge, I/Cs, and preamp. It is not the room.
So, I'm now changing out I/Cs between the TT and preamp to see if I can solve this.
The moral of the story....I dunno....keep trying! ;-)
