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?

Your welcome, Jim. Looking further at the Linto specs, though, based on the specified input loading of "150 Ohms in parallel with 4.7nF " (i.e., 4700 pf) it would seem clear that the 2M Black (which is a moving magnet design) is not the cartridge that is being used, and presumably what is being used is an LOMC. So let’s wait for further word from the OP on that.

Best regards,

Does anyone else use your equipment? I've heard (and seen) situations in which the owner's children have shown off the system to their friends...sometimes with dyer consequences (causing a tweeter to be blown back out of it's magnetic field, etc). Just curious as it seems almost everything else has been accounted for. Otherwise...any utility work performed in the area of your home? Best of luck!.

You seem to have some relevant advice to give the OP, and that's great, but please refrain from the insulting manner, in which you address others, based on your disagreement with them. This is supposed to be a civil environment.

I tell ya, there are some folks on these threads with awfully thin skin.  If this was a  sudden phenomenon, then Kosst mostly likely has it right.  Swap the amp and the preamp and see if the problem goes away.

Its not really about awful thin skin.
Its about common courtesy and civility.
In this instance Kosst could well be right for sure but there are ways and then there are WAYS of getting your point of view across.

These forums are based on freedom of speech and opinion bearing in mind the constraints of decency and civility.
Once a member puts forth a view that differs from yours you do NOT spit your dummy out and go on a verbal rampage!
That is the stuff of Farcebook and has no place here at all.

Here's hoping the OP enlightens us on some findings.
