Kleos Sibilance


Hello Folks,

I posted this in a Delos thread but I thought I'd better start it's own thread.

I have a new Kleos in a JMW 9 Signature on a Scoutmaster. I am getting sibilance on vocals beyond what I have heard with either a Shelter 501 II or a VPI Ortofon on the same table. My dealer put the Kleos on the wand I had the VPI cart on. I have gone to 1.8g and did not solve it and I have checked the alignment. I brought the rear of the arm down as well. It may be less pronounced but it is still there. Otherwise the Kleos is quite nice. It has 3 or 4 hours on it now. I do not hear misstracking on high level passages, just sibilance and sometimes some grunge on male vocals. It is not on all vocals but it is fairly common.

One person whom I wish would enter, and personally comment on this thread, would be Mr Jonathan Carr of Lyra.

This wise man is a great source of knowledge, and one who perhaps could help others understand what would help extract the best performance from his Cartridges, hence the do's, and don'ts.

I know I always carfeully study anything this man has ever written here. He's a good gift to this community, and I hope he sees my post, and comments. Mark

Why doesn't VPI use a standard mounting?<<

Define standard mounting.

Triplanar?
Rega?
Dynavector?
Hadcock?
SME?
Brinkmann?
Linn?

And why would vpi want to encourage the purchase of other tonearms with a more "universal" mounting pattern?

Do you think they'd sell as many arms?

I don't.
VPI arms don't require drilling the armboard. You simply screw it in the correct place, and set it up according to the cartridge. Very, Very easy.
markd51: Acoustic interaction? In what way?

In my case the adjustments have been checked and rechecked.

Look at their website, they sell MM's and a HOMC. One of their people told me they like heavy cartridges. Not the sort of folks that would want a $2750 Kleos on their 2nd from the bottom arm.

And don't get me wrong, I like the Scoutmaster/JMW 9 Sig. Well made stuff. Keep in mind that I mentioned that I had issues with the Shelter 501 II as well. Had to put one of VPI's weights on and up the tracking force. Also keep in mind that the problem with the sibilance was mostly solved by adding weight to the headshell.

I probably should have tried the fluid as HW suggested but I became disenchanted and have thought for years that fluid dampening is ok for tables but not tonearms.

You read the whole thread?

Thanks for your thoughts,
Robert

Point was they are not like any other. Can't drop in a Rega or an SME which would be the two most common mountings.
