Getting a new Gramaphone which doesn’t have a tonearm, I thought perhaps we could discuss the design criteria, any stand out designs or is simply one compromise versus another.

Not that I am aware of.No I just thought using the term ‘Gramaphone’ would illicit some replies from gentlemen of a certain age , who know their stuff.
Frank, Serge, is there a ‘best’ tonearm design?
Keith
I like the Thales idea but have never seen one.Frank, I hoped you would see the thread, I have followed the Derenville table/arm development I will write to them.
Are there any arms that should be avoided , what do you think of the Thales twin tube, turny Headshell designs?

Speaking with Rainer at Derenville it does look interesting but pretty expensive E30k , there is thread discussing the arm’s development here,Not that I am aware of.
The SME series V is the only one I know of which has all aspects of the bearing locations correct but being whittled from a solid lump has very little internal damping.
I favour parallel tracking but most of them have a very high lateral effective mass and very low vertical which completely screws up the cartridge output in the dross region (ie below 2x natural frequency when the output is inaccurate anyway).
I saw a german one which looked appropriately OTT, similar to the Rabco and Goldmund in concept.

I have commented on the WBF thread - I only go there very infrequently though.Speaking with Rainer at Derenville it does look interesting but pretty expensive E30k , there is thread discussing the arm’s development here,

Doesn't look like the stylus is anywhere near the plane or axis of whatever might be guessed to be the effective pivot centre of the "bearing" so goodness knows how the headshell will be moving! Certainly not as it should, anyway.
It was very wobbly with the slightest touch. No compensation built-in. I asked the vendor/designer about it and he changed the subject.Doesn't look like the stylus is anywhere near the plane or axis of whatever might be guessed to be the effective pivot centre of the "bearing" so goodness knows how the headshell will be moving!
