I have the R50 Bloom, are the other models in the zyx line more suitable to the shroeder?
I had a Bloom for a short while and measured a very high resonance frequency (13-14Hz) on a medium weight Rega arm. The compliance of the Bloom seems to be therefore much lower than the other Zyx cartridges; in fact it had a much lower compliance than the Denon DL103R. This may be the result of the very different cantilever than on the higher end ZYX. Adding mass to the arm would be a good idea. Of course Thom's suggestions are excellent as well to play with different thickness of Aluminum.
