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

I had a conversation,two weeks ago,with a major arm mfgr.He claimed that the best conductor was silver,and that "anything using gold" was inferior.He stated that gold was only useful for keeping oxidation at bey!We were talking arm cabling,here,but there must be some parallels.As for copper,I don't know.To me,from my personal experience,whatever sounds good in a given set-up,is "best".Whatever the make-up!

Also,about a year ago AJ Van denHul was interviewed,in Hi-Fi Plus magazine.He had his own take on the gold/silver/copper issue.Quite interesting stuff,actually.Worth seeking out.

BTW-DOUG,how come you can get away with a Koetsu "knock",and last fall,I almost had my balls cut off for alluding to an antiskate issue?I'm sure there are alot more Koetsu lovers out there.So my advice to all Koetsu fans is---"Let's get Doug"!!I want to see no less than a dozen posts!!! -:)

Hmm!It must be nice to be one of the "chosen few"!! -:)

Do you mean that this one has " spark " over the others ?

Dear Raul,

If I understand what you mean by "spark", I'd say yes.

The silver and (especially) the gold UNIverses lack a bit of necessary "spark". They are a bit too polite (only a little for the silver). They sound "pleasant" but they don't quite sound "alive". Some people enjoy a bit of artificial smoothing but it reminds me I'm listening to a stereo and not to live music.

The copper UNIverse does not do this. It is the most honest and therefore the most lifelike of the three, just the right amount of "spark" compared to live. I remember Mikelavigne especially liked that about his Colibri - and between the three UNIverses the copper does this best.

Regards,
Doug
Hi Tenmus.

I finished setting up my Triplainer-Shelter 90X a few weeks ago. The first thing I played was Swan Lake. The arm shook so badly that I ceased playing the table The next day a call to Tri Plainer resulted in the suggestion that I back the damping screw all the way out of the damping trough.When that didn't work I just stopped playing records, until today. Of course, nothing changed over the last few weeks and the same thing happened.

A light bulb went on and, Audiogon forums to the rescue. Lo and behold I found your forum posting of the same problem I experienced. The replies were enlightening.

I have only one question that might have been answered, maybe I missed it. If increasing the mass of the arm was accomplished by putting the heaviest weight, the only one with the chamfer, all the way up to the pivot point of the arm I assume that the chamfer was pointing to the rear of the arm. Would you please confirm this.

I am posting this reply to your forum topic as well as emailing you a copy, as it has been awhile since there's been activity on that site. I am anxious to hear how good this set up sounds.

I was unable to access your system on Audiogon, maybe I just didn't look in the right place. If you have a system description on Audiogon, please point me in the right direction. Regards, Ken Kftool
Kftool,

The normal setup for a TriPlanar has the chamfer pointing toward the arm bearings, not away.

Assuming proper setup, there is no reason for a TP/Shelter to "shake badly", on any record. If the problem is as bad as you describe, changing counterweights and counterweight positions is not the solution. The effects of those adjustments are fairly subtle.

Tenmus' problem was only resolved with a replacement arm. I'd suggest contacting your dealer or Tri Mai. If I had to guess, I'd guess the bearings might be misadjusted. But that is not a user adjustment.
