Benz Lp-s Frequency Resonance Problems


Hi to all,

As i mentioned on another thread, i have some problems with my Lp-s on my Graham Phantom arm, i have problems with little warps. I have measssured with the Hifi News Lp and lateral i have between 8hz-5hz and vertical i don't know well as i can't see cartridge wobble or hear any distortion. But for my problem the important is the lateral test.
Benz recommends medium to high mass arms but that's impossible!
To get 10hz frequency resonance you need a 0 gram mass arm!

I don't know if to try a Reed arm, the lightest one is 10gr effective mass and i should have 8hz Resonance frequency.

Any idea?

Many thanks

Doug...good suggestions. I think also that the cartridge should be sent back to Benz for them to check. Too many people have great success with this cartridge on too many arms for this to happen only to the poster.
My LPS is absolutely wonderful on a VPI Superscoutmaster Rim Drive with a 10.5i tonearm.
My LPS is tracking flawlessly in my VPI. I had to get a weight to properly balance it, however, it is beautiful now. I would call Graham and ask them
