Kleos Sibilance

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.

Hello Bill (Audiofeil)
I know this sounds like a discussion that appears to be going back and forth, "yes it will-no it won't", but in the hopes of learning something, and hoping you folks will share some of your seasoned knowledge, why do you think this is?

Is it maybe not so much the JMW Arm can be accused of being poorly built, or would you say it is more a cause of the type-design of Arm it is, that it is a Unipivot?

I'm reminiscing back, to hear Doug D's words, when he once gave comment about how he noted that some Unipivots he teamed with some of the ZYX Cartridges, just didn;t seem to cut it. If I remember, his term was "wooly", and I know wooly can be a vague term to describe, but do you think that this what what Doug was getting at, that in some cases with these highly revealing MC Cartridges, that the Unipivot design may be a wrong choice, and falls short?

I know you see the Hadcock, I believe another Unipivot design. So is the Shroder, right?

Is it a mismatch of compliance, or something else then?
