I am curious about some of your tone arm parameters. I am not suggesting that you are wrong I simply am an ignorant analog novice trying to learn something. Why can't the arm wands be effectively damped to stop resonance. Is it because damping materials used would be too heavy? Or do the laws of physics dictate that any length of a tubular structure will have a resonance frequency regardless of efforts to minimize its effects or to get it out of the audible spectrum?
How does the arm interact with the cartridge if the correct effect downforce and minimal restriction on the pivot point is observed such that the stylus compliance would be altered? I guess the mass of the arm restricticts it's motion to some extent but why would'nt the stylus be free to move as a function of its suspension?
I like linear arms BTW but never afforded anything beyond a number of ebay Technics TT in marginal condition.
I can't understand what benefit completely decoupled counterwieghts could function. They would have to exert a force on the arm, in some way to be effective. I have to ask what the most ridgid structure would be? I understand the shorter the better so lets effectively eliminate an are beyond the slide for a cartidge to run arm as in the linear tracker.
Isn't the usual damping used on the stylus enough to maintain the effective downforce to track the groove effectively despite some inevitable vertical deflections. Why not extend the stylus beyond the pick up coils and attach a vertical gas filled shock absorber. WTF do I know but could the MC type cartridge still function with this restaining mechanism? Should I patent it?
