Benz LPS Sounds Bad, Very Bad at 45 RPM


Well this may be an issue no one has heard before but i have a fresh Benz LPS with maybe 30 hours on it thus far. It sounds very good at 33 1/3 RPM but sounds horrible (sort of a distortion that my wife can clearly hear) at 45 RPM on anything I have tried (Music Matters Blue Notes, AP Blue Notes and other high cost 45RPM recordings)

Did not have this with my Ruby 2

any thoughts??

Dear Davidriggs: If the overall cartridge set up is right the IMHO what you are hearing seems to me a problem with cartridge traking distortion.

45 RPM puts higher demands ( over 33 rpm LPs. ) on any tonearm/cartridge combination but on my experiences not so hard to have the trouble you have. So could be that the cartridge suspension is in trouble or that in your analog rig the tonearm/cartridge combination is not well matched.

To be sure maybe you have to mount the cartridge in other tonearm and run the same recordings in your system and see what happen.

Regards and enjoy the music,
Raul.
I believe you might be experiencing some VTA or tracking force issue, related to the thicker 45RPM LP's. My first Benz seemed to be senstitive to the changes of LP thickness. I remember reading about Fremer's DIY trick about changing VTF when using a thicker LP to overcome VTA issues. It might work or not, it did for me. I have sinced upgraded to the LP S and have not any issues regarding distortion or tracking. I use an SME V arm and track at 1.8 grams. I aligned with the SME arm guide and the Mobile Fidelity protractor.
Good luck.
