Raul,
Excellent question/suggestion re: arm/cartridge matching. We should have asked that earlier.
Jtimothya,
Thanks for the update on the SME Vd with azimuth-adjustable headshell. That seems like an excellent solution, which I was unaware of. (The two SME V's I am familiar with, from friend's systems, do not have this.)
Drilling out the headshell holes (by hand) is a reasonable accommodation, though I'd prefer to use a hole-sized bit and expand them *only* longitudinally and not laterally. If TriPlanar owners can fiddle with sandpaper and O-rings (per my "Tips" thread) I don't know why SME owners can't fiddle with a drill bit!
Perfect sound forever, anyone? ;-)
P.S. SirSpeedy is right about the "free" feeling of the TP while hand cueing. It feels like I imagine how zero G would feel. There's so little resistance in any direction it's kind of scary at first.
