Triplanar VII tonearm & Koetsu Jade Platinum cart.

Hi all

I have the above combo on my Kuzma Stabi Reference. To me, the combo sounds great; and so would like to hear from others who has the same combo, and what their opinion is on this combo.

Secondly, would also like some tips on how to fine-tune the installation of the Koetsu using Triplanar's many features

Looking forward to your opinions and help

Cheers ... Peter

In the US the online retailers sell headshell shims for this purpose. They can mount on top of a TriPlanar headshell to avoid affecting VTA.

You could DIY some yourself pretty easily. You might try different materials, since their effect on resonance behavior will vary. Shims like this muddy the sound of my ZYX UNIverse, but with a Koetsu it might be different.

In the case of effective mass, it is a different calculation than the mass of the arm. I am not 100% sure but I feel it relates to inertia. In the case of a Dynavector arm the effective mass can be altered by using a high mass headshell. On the inexpensive side use some blue tack. Place it under the headshell or on top and some on the counterweight. It is cheap enough an experiment (About $10) to learn the effects of mass. This renders most tonearm upgrades / swaps superfluous since now you are able to test mass changes rather than arm changes. Using a penny stuck on top of the headshell w. blue tack can do the trick as well. Just use a test record before & after & determine your resonant frequency. Listen before & after the change. You should easily learn the difference. Unless the arms bearings are not up to it you should be able to easily hear how mass relates to compliance and effects freq. response. Good luck.

I spoke with someone today who has alot of experience with
the Koetsu stone bodied cartridges. He basically said that
there is more to matching the Jade than mating it w/ a high mass arm. He stressed that energy dissipation was important, because the stones give off more energy than their lighter counterparts. This energy than travels through the arm. He felt an arm that would do a great job of releasing or dissipating this energy would be the SME 5. He did concur that the SME had a warmer balance than most arms. However, still felt it would bring out better highs and deeper bass.

FWIW,when I went through my ten year Koetsu period(owning a Black,Onyx,Onyx Platinum,and Urushi)I had two different SME-V arms.I must admit the arms seemed very good with these cartridges(to me).
Good luck

Hi all

Thks alot for your help, and keep them coming.

If I did not respond to yr help with the results of whatever remedies that you recommended, it is be'cos I am constantly travelling and maybe I will have some time in the near future to try something out

I will perhaps try a penny with some blue tack and see how's it going and report back

Cheers ... Peter
