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.

Socoaste, I still think, based on the notes published on the First Watt website, that you should call them and find out how to configure the parallel loading networks to tailor the driver response. As Raul mentioned, and I agree, I think the problem is due to impedance mismatch between the amp and the driver, and it should be quite easy to rectify. With these kinds of amps and speakers, it's a bit like loading a moving coil cartridge -- very critical, and will (almost) never work "right out of the box."

Socoaste,

The Fostex drivers you use are very interesting and yes they dont have a whizzer (good) but they do not give you the upper crust of high frequencies, thus you get ssssing.
Do try a super tweeter, play around with IC.

I am almost sure your speakers were voiced with SET amps.

I am sure Raul will back me up on this one: Try a tube amp.

Hola Raul.

I had extreme sibilance, so much so that I could only listen to about 20% of my software. For a (very) long while I tried to make my system darker, but the darker I made it the more noticeable became the sibilance.

I now have zero sibilance and I attribute it sole towards my stands. Your problem my be different from mine, but after getting a decent platform/stand both my analogue and digital source produce no sibilance. I can actually listen to Sarah Brightman without knives going through my ears.

any conventional loudspeaker needing modest, quality power will perform admirably with the first watt. your old friends balance and bass will move back in with you as well.

Dear Socoaste: +++++ " speaker to amp mismatch....well, I know a few persons that
have the F-1/Hornshoppe combo & they are quite happy with it. " +++++

If you already heard those systems and you find that don't have your problem ( not even approach to your problem ) then other than the mismatch between speakers/amplifier/cables it will be a fault in the speakers drivers or a fault on the amplifier, what else?
Why not take your amplifier and hear it with any of those systems or take the amplifier of one of your friends system and hear it on your system?

Regards and enjoy the music.
Raul.
