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

The weight of the LPS and its compliance suggest that the resonant frequency will be on the low side with the Phantom.
What turntable are you using?
Sometimes its how the turntable deals with low frequencies - ie perhaps there is a resonance being excited in the turntable/suspension?
It might be helpful to know what tables the other Phantom/LPS owners are using.
