Kuzma 4Point Tri-Planar

Hi Mike,
My remarks to Doug were merely meant to indicate that there is some question in my mind whether the cartridge vibrations have an unimpeded path into the wood arm tube in the first place. If the mechanical energy put out by the cartridge cannot get to the wood, then those properties of wood cited by Doug would not be of any benefit. Because the rudimentary headshell consists of a piece of brass(?) held at an angle against the flat surface of the wood, I wonder how efficient is the pathway of energy transfer. This all goes without saying that I heard the Talea in a system using speakers like mine (Sound Lab) and amps like mine (Atma-sphere) and absolutely did like what I heard, very much. So regardless of the physics and these airy discussions, the Talea does a lot right.

I read Romy's remarks referenced by Audiofeil. It's OK with me if he wants to blast Fremer, because Fremer is sort of in the public domain and is willing and able to defend himself. But his shot at Mike was unconscionable and unforgivable, not to mention senseless and unnecessary. So what is Audiofeil's motive here?

Doug, Just now after responding to Mike I read your two posts above mine. So the issue is what is the coefficient of energy transfer between the piece of metal (which appears to be brass) and the wood arm tube? Since Durand undoubtedly used a "hard" wood, and like substances wrt density usually present the least impedance, energy transfer may be good, or it may not be so good. Having only one bolt there does not suggest that one could attain a really tight boundary between the two, which would also facilitate energy dissipation. I am only thinking out loud here, and no slur on the Talea was intended. If Durand and his team found that this construction sounded best, and it seems they did, then I really don't give a darn about energy transfer per se.

So what is Audiofeil's motive here?

Probably an example that taste can be different.

But here is a guide to do it right

cheers

Lewm, one bolt is plenty. The surface contact area between the brass mount plate and the "headshell" is about 1 x 1/2". If there were vibrations not allowed out of the cartridge, or not drained away through the arm and base, you would have heard that as a nervous presentation. I assume from your comments that there were no such objectionable issues.

I think this just about says it all, right here ...
