Why does my system now have shrill top end.

The equipment in my system (listed below) has not changed but I now find on both CD and Vinyl a high end shrillness to the sound (treble is very harsh) that has become very annoying, especially at high volume levels. I have no idea why this happened all of a sudden.

Endevour E-3
Pass 30.8
Pass XP 20
Esoteric K01x
Linn LP12 (Ortofon Black cartridge)
Linn Linto Phono Preamp
PS Audio P5 (Amp plugged in directly to wall)
JL Audio F112 v2 sub
OCOS Speaker cable (15 feet)
Pass XLR interconnect (Preamp to Amp)
Harmonic Technology Cable Magic Link (not current version). RCA termination

Any ideas?

About a year ago I was experiencing system symptoms virtually identical to those the OP has described. At some point after much thought, frustration and experimentation, I replaced my speaker cables and the harshness disappeared. 

30 feet of Monster Cable or 12 gauge TW cable from the hardware store will be an easy and inexpensive experiment. Hope this helps.
