    Does anyone have any experience with this cartridge?

    John-I forgot the gain you have available in your phono section. This is a fairly low output cartridge (.3mV) and you will need lots of clean gain to make this cartridge come to life.

    before you consider something like a 103 is the effective mass of your arm >15gms and adding more mass to the headshell IMHO, doesn't cut it.

    Looks like your gain should be OK, but the mass of your arm appears to be on the light side.

      That's a shame. I've always heard good things about the 103/103R and wouldn't have minded to try it out. It appears that so far I can't use Grado (incompatible with Oracle), Charisma and now the 103.

        Arms and the gain in phono stages set your boundaries for which cartridges you can use.

          Have you asked Oracle about some carts they like on their arm?

          Johnny I don't want to kill your idea out of the gate, you CAN get the Zu 103 to work in an arm with your effective mass but IMO its sub-optimal. If you go with the stock, plastic-bodied 103r its 8.5gs the Zu is almost 15gs, the problem with the Zu is you've increased the tip mass on the stylus which has a deleterious effect on moments of inertia and how well the arm tracks with the cartridge. with a low compliance cart such as the 103 that tracks at 2.5gs its going to be okay but something to consider nonetheless.

          The optimal way to increase the effective mass of your arm is not adding it to the headshell but near the pivot. I believe Ralph Karsten once sold a 'wrap' that was taped around the arm tube and stuck near the pivot so you could effectively increase any tonearm's mass where it makes sense, it wont look pretty but it works. You may also need a heavier counterweight, esp if you go with the Zu.

            Zu do sell a weight. I bought one awhile back for my technics 1210. I'll check for the name of it.

              Rob /Tunes - I have 2 additional weights that came with my Oracle, so I should be good. I'm using the least heaviest one with the Dynavector.
