I have two Luxman PD-444 and many arm bases for them. One of the best tonearm would be FR-64fx, for you it can be PRO version of this tonearm designed for radio deejays / broadcast. This is expensive tonearm!
Another great cheaper option is Denon DA-401 tonearm, this is a light mass tonearm.
What is your cartridge?
