Koetsu cartridges - what arms work?

Thinking about Koetsu RSP or Jade for a VPI 3-D arm.
Good match or not?
Thanks.

I bet the new technics 1200G would sound great with a Koetsu.  I have been thinking about it.

I know it’s been done, and I haven’t tried it myself, but my instincts are going hard against that one. You want heavy mass and rigid bearings -- neither of which the VPI arm seems to provide, though the new 2nd pivot might help.

You really don’t see any VPI arm owners extolling the virtues of Koetsu. That says a lot.

Also, maybe unrelated -- back when I ran a SOTA Star as my 1st table, I almost bought my dealer’s VPI arm to mount on it, but SOTA told me in no uncertain terms that was a BAD idea. Suspensions and VPI don’t mix either.

Racedoc, This is in response to your post of 10-13-2017.  Therefore, you may never see it.  I am not sure exactly what Peter Ledermann may have told you regarding skating force and the Viv Float.  But it most certainly does generate a skating force at all points on the LP surface except that one point where the arm wand (and presumably the cantilever/stylus) is tangent to the groove.  At that instant, skating force = 0.

Conventional tonearms can achieve tangency to the groove at TWO points on the playing surface of the LP, which is the whole reason for stylus overhang and therefore headshell offset angle.  However, even at those two points of tangency, there will still be a skating force, due to the headshell offset angle.

What the Viv and the RS-A1 may be telling us is that our obsession with tracking angle error is misplaced.

I ran a Blue Lace on a 12" 3DR arm, worked but far from optimal results.  You can purchase a great condition FR-64S for $2500 that works excellent with Koetsu.
