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

Dear friends: Here are some facts about why exist the SUTs for LO cartridges ( at least is my point of view ):

- In the fifthies appear the MC LO cartridges ( As a fact: Ortofon invented in 1948. ). In that time all the phonopreamps were designed for HO cartridges MM/MI/etc. No one was in the design of high gain PP because no body need it.

- Ortofon and latter other MC LO cartridges never ask to the PP designers/builders to manufacture a high gain PP for their MC LO cartridges. What I mean is that never exist a cooperation job between the MC LO builders and the PP manufacturers.

- What was the comercial attitude of almost all MC LO cartridges builders?: to put on sale their MC LO cartridges along with a SUTs ( designed for it self ) for those MC LO cartridges.

- I can remember from Ortofon when they design the MC10, MC 20, Mc 30, Mc 2000, Mc 3000 and MC 5000, cartridges at the same time they offer the respective SUT: T 10, T 20, T 30, T 5000.

- Like Ortofon everybody do the same: Denon, Audiocraft, Fidelity Research, Koetsu, Micro Seiki, Accuphase, Dynavector, Highphonic, Audio Technica, Entre, etc, etc.

- In the mid-time what does the PP designers ( SS or tube ) for the development of a high gain PP?: almost nothing, almost all take the easy " cheap road " ( wrong/worst one ): that the customers buy SUTs along with their PP if they want to handle a LO cartridge. Some of the PP designers/builders incorporate in their " high gain " PP internal SUTs, exactly like today ones.

- No body take the challenge to design a HG PP with out SUTs. There are some exceptions: Curl, Levinson, Pass, Klyne, Classé, D'angostino, etc, etc,

- So we all are suffering the " easy road/ wrong road " that almost all designers/builders take it more than 55 years ago.

- All those comercial attitude never take into account us: the audio customers and never take into account the QUALITY MUSIC/SOUND REPRODUCTION. They don't care about in those times and many of them don't care about today.

Fortunatelly, in the last few years, some PP builders finally take the challenge ( others like me designed our self ones ) and we have some very good HG PP, many of them at very high price.

This change of comercial attitude: Bravo!!!!!!, could tell us that the best about is coming because the developtment of HG PPs are really " starting ", it is not a mature industry.

Regards and enjoy the music.

You are speaking of PP with high gain and no SUT in it is it the case of the JADIS JP 80 MC version?

Who are these other builders and which models are you thinking of ?

Thanks
While your out swimming in your Tux, be catious of the Man in the Grey Flannel Suit! He usually has a huge grin on his face.
Doug,could you enlighten me,as to the differences between the ZYX Univ "silver vs copper",as this is of interest to me?Thanks,in advance.
SirSpeedy,

I've had three UNIverses in my system: copper, silver and gold coils. (Gold is by special order, Mehran doesn't stock them.) The price is the same for all three IIRC.

The sonic differences were precisely the opposite of what I expected, precisely the opposite of what electrical conductivity would lead anyone to expect.

COPPER
Most neutral, least colored, comes closest to achieving live microdynamics, reproduces natural waveforms the best. Probably the most Colibri-like of the three UNIverses (remembering Mikelavigne's comparison). Easily my favorite and Paul's. Requires the most careful attention to VTF and especially VTA/SRA. No gain without the pain.

SILVER
Slightly warmed/smoothed, almost Koetsu-ish, which means we didn't like it at all. Mehran sells about as many of these as copper and many people love it. Just not our cup of tea, we do not tolerate rolled off transients. Cello and Vetterone also prefer the copper, but if this is the kind of thing you like, you'd like it!

GOLD
Very warmed/smoothed, more Koetsu-ish than a Koetsu. Personally it made me puke, but gold resists harsh chemical conditions well so it survived the short visit and the trip back to Mehran! Grado fans might enjoy it, or someone with a terribly edgy system that needed taming. We prefer accuracy at the source and fine tuning later if need be, but YMMV as always.

It took me forever to puzzle out why superior conductors created inferior results, but it's obvious if you forget electricity and consider the whole picture. Silver is denser than copper and gold is denser still. Extra mass on the cantilever means reduced transient speed and rolled off waveforms. It's like Twl's HIFI mod, mis-applied. Greater inertia on the tonearm increases stability, greater inertia on the cantilever impairs stylus freedom.

For me, this A/B/C comparison settled any argument about HO vs. LO MC's. Here were three identical MC cartridges, all of them highly resolving, the only difference being the coil material. The lowest mass coils produced notably more accurate results even though they were inferior from an electrical standpoint. End of argument. If the stylus can't trace the groove right it doesn't matter how well the electrons flow.

Doug,thanks for the interesting comparison.

"More Koetsu-ish than a Koetsu.It made me puke"-

Now I have to admit that it's a dead heat,in terms of "great post quotes",between Raul's "swimming in a tuxedo"(I really laughed at that one)and now this,which is funny,yet the puking part doesn't tickle me,as much-:).STILL,it's a tied ball game,between the two of you!!

Best!
