Tell me about saec 308 Long tonearm

Hello,

Could you please tell me sth about that tonearm ?

I am completely inexperienced with it.

I don't have even a table for it yet.....

Why it is specific, why it is good, is it difficult to instal it , to set etc ? What it is compared to MS ma-505x? (Which I don't know either....)

what are best cartridges for it, of course?

This kind of things....

Thank you very much

Serge
