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?

Next up, the absolute polarity thing. Or the Cable Directionality thing. Or the fuse directionality thing. Otherwise it looks like we’re back to them old Morphic fields back home. Waves of...information!

When you plugged your amp into the P5, did it do anything for the harshness?

Do you leave your front end equipment on all the time or turn it off when not in use?  Warmup could be in play.  Is this for both LP and Digital playback?  

Second on Almargs comment about the OCOS Speaker Cable - 15 feet is a long cable - try a set of Canare 4S11 they are pretty inexpensive and a great value.

Best of Luck

What the hell is up with you nutjobs and your snake oil fixes????
It sounds like something is wonky with the power supply in the amp. Not cables!!! Not morphic fields! Idiots!

You discovered why snake oil (fancy cables etc) works - it all starts with faulty equipment and goes exponentially from there....
