Regards, voolston:
Apples CAN be compared to oranges, or, bananas to broccoli. May I suggest there are varying degrees of harmonics, smearing and ringing relative to the materials present from stylus to turntable?
It may be a stretch but the proposition that performance, either heard or measured, is identical relative to the implementation of ceramic, wood, magnesium (or whatever material) introduced in proximity to the cartridge's generator might be questionable.
If you wish, take a moment and visit:
where headshells are evaluated relative to the above considerations. Interesting stuff. I've done three "garage built" cartridge conversions to wood body, an AT, a Shure and an Acutex. It made a difference. Lacking the ability to measure performance, wether or not an improvement may depend on the priorities of the listener.
Peace,
