Help ...... excesssssssive sssssssssssssssssssss

I would be eternally greatfull of any asssssissstance
given to remedy a condition that my ssssystem is ssspewing
out.

I guess it's called Sibillance.
well it ssssssucks.

I have tried inserting different preamps/amps/tubes as
well as 3 different cartridges (shelter 501 II, Grado Ref.
music makerIII )
no help.

different cables have been tried too.
I used the VPI jig for setting up the cartridge & used magnifing goggles to get it right on the money.
VTF set at 1.75gm
always playing with VTA & no help.

I am wondering if the tonearm or wiring could be cause?

here is my setup:
VPI TNT Base
Teres wood platter
JMW12.5 Arm
Music Maker III cartridge
VPI phono cables

Mapleshade copper ribbon I/C's
Decware Preamp
Decware Phonostage
First Watt F1
Mapleshade Speaker cables
Hornshoppe Horns

The music my system makes is wonderful EXCEPT for the
sibillance exageration, if I can get rid of this problem
I will be an extremely happy camper.

Just a guess, speakers?

The first obvious question relates to system set up. Have you eliminated hard surfaces at the first reflection points on the side walls, floors and ceilings? They are a big contributor to sibilance, overall brightness, and 'distortion'.

Second biggest contributor (If not the first - I'm not familar with your speakers), are you listening to your speakers on the speakers axis? Many speakers are hot on axis and must be pointed straight ahead, or something in between. On occasions I have gone so far as to toe my speakers in so that the axis crosses in front of my listening position to avoid both sidewall reflections and still listen well off axis.

Lastly, have you listened to other sources on your present stuff and found the presentation to be with out the same sibilence?

I'll not comment on the wires. While I've found wires can seem to be a contributor to brightness on occasion I have no experience with your equipment. Perhaps someone with your stuff will have first hand knowledge, but FWIW I've never been able to tame sibilence with just wire changes.

Have you noticed any change in sibilance across the LP (i.e., outer track compared to inner track and middle track)? Also, try increasing your tracking force to 2.0 grams. Finally, try a different alignment protractor.

Also, and my apologies if you already know this, ensure that you are aligning the cantilever and not the front of the cartridge - I'm not familiar with the VPI alignment rig, it may "force" you to align correctly.

Good luck and keep us posted on your results!
