Denon DA 307 and DA 309


Hi, anyone know the effective mass of these tonearms?

Perhaps the only difference is that the 309 has an overweight to add to the counterweight to balance heavy cartridges 

I have a 307. I have used it successfully with the Denon 103 mc cartridges. An excellent arm!

This is a too easy match, but would an Ortofon MC 30 or a Nakamichi MC 1000 or a Sony XL 55 Pro, or a Denon DL 304 or a more recent cartridge, for example Ortofon MC 20 Supreme, be fine anyway?
