Default Denon Dl-103 resonance frequency

Dear all,

I read on this forum and in many articles that the Denon DL-103 is not a good match with the medium weight Rega arms and that it prefers high mass arms.
Indeed the resonance frequency I computed using the specified compliance and one of the many charts that can be found on the web is high at about 20hz (if I well remember).
However I now had the opportunity to measure its resonance on my Rega arm by using the Hi-Fi News test LP and I got 13hz which is a rather good value.

I am interested in your opinions

Thank you

Renato

I think I've seen similar comments before, but pretty sure the cartridge was in either a wood or aluminum body, not the stock plastic one.

Had found its useful compliance spec to be ~15 on test record by watching the resonance on FFT and having its mass along with mounting and arm masses checked.

I'm using a DL103 on my RB250, with the plastic body and test record the resonance was 10 Hz azimuth and 8Hz vertical. I did cheat though as I'm using a Townshend Rock and had the Trough damper in place. I have now changed the body to an aluminium one (similar to ZU) and this has added some mass I shall have to remeasure at some stahe.

My Denon is the standard stock (plastic one). However I forgot to mention that my Rega arm has been rewired (Incognito kit)
