Questions Regarding Installing a Wheaton Triplanar On A SOTA Cosmos


As luck would have it I recently acquired a Wheaton Triplanar VII U2, and am waiting on it being shipped. So at this point I am trying to decide what the most favorable table to mount it on, and what arm gets replaced. I have a SOTA Cosmos Eclipse with a SME V on it, and that would be my preferred place to install it. The only thing is this Triplanar has the arm cable extending out the back of the arm pillar instead of routed out the bottom of it. I have to assume the cable is going to have to be routed on top of the arm board and then over the edge into the body of the Cosmos. Not wild about that but do not see any other options other than drilling a 1/4 hole and routing the cable through it. Anyone have any experiences to share if they have installed it on a SOTA table?

My second alternative is to put the arm on my Scheu in place of a Dynavector DV505 I have. That is certainly a straightforward option, with no issues to be solved. However, I have never been fond of the SME V on the SOTA, so this would be my first choice.

Neon, I lost the thread somewhere. Why does mounting the TP on the Scheu prevent you from auditioning the MC2000? Thanks.

@lewm The arm effective mass is 11 grams, which is higher than I feel comfortable running the cartridge at. I never could find a vertical effective mass for the vestigial arm on the Dynavector, but I always ran the lightest head shells I could find. In the end I used a Denon that weighed 5.6 grams. 

I’m running my MC2000 on my Reed 2A with the red cedar arm wand. Probably effective mass in the 10-12 Gm range. No problem. Anyway the TP is in that same range for effective mass. So in that hat respect you’re no better off with the TP. If you want to be a slave to the formula for resonant frequency, then there’s virtually no modern tonearm that works (according to JG Holt you need a 5gm tonearm). Just go for it. Nothing will break.

I have had a search and discovered  Modern Production CF Heads Shell that is claimed to be 5 grammes.

I can add a link if of Interest? 

 

Can you name the specific brand and model, because I own several CF headshells, made by Yamamoto or Oyaide, and they all weigh around 8-10g. Vintage headshells usually made of thin, perforated aluminum would weigh less.
