Will Michell Technoarm work with Denon 103R?

Technoarm is based on the Rega RB250, same as the OL Silver. Both are classed as medium mass arms and should work fine with a DL103. If there is a difference in effective mass it shouldn't be sufficiently different to cause you problems.

I've just heard that my Expressimo is being shipped today. I'll be fitting a DL103 in it.

You can apply the HiFi mod to the Technoarm, in a very similar way as the RB250. Just Blu-Tack the weights onto the sides of the bearing housing, so it appears like they are extensions of the bearing axle, and it will work fine.

Very worthwhile mod when using the DL103R.

Thanks for the responses!

I guess the main piece of my question is about the effective mass of the arm. The michell technoarm has holes cut in the arm that reduce the effective mass of the arm. My understanding of the hifi tweak is that the main point of it is to increase the effective mass. Given this effective mass difference (I'm not sure what the actual #s are) would the OL Silver be a more suitable arm to the Denon 103R cart? Or will the tecnoarm with the hifi mod be just as good a match, even though it has less effective mass?

Thanks,

Todd

If you fit the HiFi mod to either arm, the effective mass will be fine for the DL103R. Yes, there is a little difference in mass between the two arms, but with the HiFi mod on them, you won't notice it.

I think that the OL Silver is the better arm, but the Techno Arm has some nice features with the counterweight, and wiring upgrades.
