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.

"Bill identified himself as a dealer in his first post in this thread. At the bottom of his post it says "Dealer Disclaimer". That seems pretty transparent to me, but English can be a funny language. "

Yes but many folks come into these things in the middle or later via searches. And he seems to have a strong anti VPI sentiment. I may be particularly cautious having sold Audio/Video in the past and know how some can be.

On the other hand, I plan to call him Monday.

Moving on, it may be breaking in but a few minutes ago on the first side (cart warmed up already) of Featuring Norah Jones the sibilance was quite pronounced on some cuts. I will probably try the dreaded anti-skate contraption and maybe a drop of dampening fluid if the sibilance does not abate soon.

What would you folks think of the 309 on Gyro SE? I really cannot afford to spend any more money but I cannot live with the sibilance. Sibilance is the reason some digital drives me batty. Not that anyone could tell.

Appreciate you folks helping:-)
Agree with above comments that you should break it in longer before judgment. It is also worth checking to see if a change in effective mass affects the sibilance. Try weighting the headshell with a 5gm nickel & rebalancing the counterweight.
As the Kleos is a more revealing cart & w/ the Lyra carts being on the detailed side of things, few things i can comment that possibly contributes to sibilance in no particular order:

1. improper alignment & overhang
2. tonearm itself
3. phono stage
4. break in issues
5. Lp software itself

With this in mind, has anyone here had the Delos before upgrading to the Kleos ?
"Try weighting the headshell with a 5gm nickel & rebalancing the counterweight."

Yeah, thought about something like that. I have some Blu tack or similar. I might stick some of that on the headshell and rebalance. The Kleos is 8.8g which is heavier than the Helikon. Elusivedisc is selling a package with a Scoutmaster, 9 sig, and Helikon. Theoretically since the Helikon is lighter, if it works in a 9 sig, the Kleos should.

The cart has the ability to bring instruments and voices into the room like no other I have heard. Gotta make it work. It may bankrupt me, but gotta make it work.

:-)
PS: The Gyro has the funky motor and slow pacing so that is out.

Disagree.

A 0.05 gram difference in effective mass is insignificant.

More importantly, IMO, is the difference in design between Helikon and Kleos regarding coil alignment.

I maintain this cartridge is too much for the arm to handle properly. It won't track a Zyx Universe, vdh Colibri, or Dynavector XV-1t with any precision as well.
