I have a Zyx 4D cart running through a JLTi phono stage which is rated at 55db The Zyx is rated at .24 mV output.

Looking for a new cartridge (and maybe phono stage) for my Rega RB808
Rega RB808 tonearm effective mass is 10g according to this article. Add the mass of the cartridge and screws when you will calculate tonearm/cartridge resonance, read here how to do that. If your combo will be within 7-12Hz then you can use it. If you’re out of that range you need another cartridge (difference compliance). If your cartridge dynamic compliance in the manual stated at 100Hz then you have to multiply it on 1.7 before you will make any calculations. Cartridge compliance at 10Hz is the key. After you will convert cartridge compliance from 100Hz to 10Hz (*using x1.7 formula) you can go back to the ortofon diagram for correct calculation of the resonance frequency. The rest is a matter of personal taste, there are so many different MC cartridges available, but some decent MM are simply better, especially on your TT and your tonearm. |
Phono gain is one factor but it plays in with preamp gain and amp input sensitivity (or gain if you will). Without the full info it will be a matter of experimentation... Btw do you have shims or vta adjuster to allow vta changes? You could try the ~.5mv Sensitive Sound ART Dark that I import if you like. Its right at home on this arm mass. |
