Shelter and Triplanar matching ?


HELLO

I have problems to match a shelter 901 with a tri planar VII.

Lot of records ( above all piano LP ) are playing tremulous and I can see the tonearm CLEARLY SHAKING on the record while playing it as if it could be a problem of resonance between the cartridge and the tonearm .

I have seen here and there that the Shelter was a LOW COMPLIANCE cartridge (I don't know the exact value).Its weight is 9,5 g.

I have choosed the maxi VTF : 2 g.


I am afraid that the TP is too light for the shelter.Its effective mass is 11 g,
Is it enough for the Shelter 901 ?

I am surprised because the Shelter 901 / Tri Planar seemed to be a combination used buy some audiophiles...without modification .

Could someone give me some help...

Thank you

Hi Doug and Raul

At last I have received my new TP for two days.

Every thing looks OK .

Doug.

Your advice about CW works perfectly ...still just some problems with bad records but 90 % of my collection are listenable.

Could you please tell me what kind of wire is mounted with the TP ?
Many thanks to you.

Raul

Thanks to you also for your participation ...

The combination Verdier /Tri planar/ Shelter is technically OK and really great musically ... even if there is still a lot of possible progression .

Bon jour!

Very glad to hear the replacement arm has solved (most of) the problem.

The standard wire on a TP is Discovery (copper). I've never heard a TP with any other wire, so have no comparisons to offer.

Next step: Drive system upgrade? Cartridge?

Regards,
Doug
Dear André : +++++ " still just some problems with bad records but ..."+++++

Something is still out of " target ". Which the problems with that 10% of bad records?

I insist on it because in any of my tonearm/cartridge combinations I have no problem at all.

Regards and enjoy the music.
Raul.
Bonjour Doug and Raul

TO BE MORE PRECISE I should say 99% of my records are correct. Some of my Lp ( most of them are second handed) have a succession of tiny waves certainly due to warmth or bad stockage or both.On these records of course the TP / Shelter still shakes but I think now that it is normal ... I only didn't hear it with the Rega /audio note because it was less transparent and perhaps (???) the TP/Shelter has less tolerance than the Rega / audio note when reading a bad record .
Of course it doesn't matter.

I think I still have to improve the Verdier ( try the Teres motor with the mylar tape as you told me before)
The Shelter is quite new... but I effectively already think to go farther perhaps with a Zyx ( wich model to really feel a difference?) or the Shelter 90 X or a Koetsu ( Rosewood ) ...I don't know wich one would match the best the TP

I am also in relation with the Audio Note dealer here in France , he is a very kind and serious guy ... Did you already hear the Audio Note cartridges ( the Io I for example) ?

You tell me that the Tp 's wire is copper , is it a problem if the two next modulation wires( From step up to preamp and from preamp to amplifiers)
are pure silver ( audio note AN V).
Would it be better to have exactly the same wire ( discovery) everywhere?

A bientôt

Yikes!

Well, the TP is one of the great tracking arms, certainly much better than my OL Silver, which is similar to your Rega. But I don't have any records quite as bad as what you described.

A ZYX is a better theoretical match for a TP than a Shelter or Koetsu. But it's also important to ask this: What kind of music do you play? Can you describe your sonic goals? What do you like best (and least) about your 901?

You apparently haven't heard a ZYX or Koetsu, but they are very different from a Shelter and also from each other. You will hear major differences between all of these.

It's certainly not a "problem". It's just a matter of sound. I haven't tried all silver wire so I can't say what differences you would hear. Even those who have tried it might not know how it would sound in *your* system. With wire, tubes, resonance control, cartridge setup and other "tweaks", hearing in your own system is really the only way.
