FSE ( Field Stabilising Element ) on a Cartridges which I am familiar with. Has a very positive influence and benefits way beyond the same model Cart' demo'd without the FSE added. The Cart' with FSE was proven to be much improved in the produced End Sound quite substantially, I wonder how well aligned in general the Ortofon Cart's are for their Zenith orientation.
I wonder if the Cart' without the FSE, if was to have a ideal Zenith alignment and was nailed on the other Geometry, whether it would have outshone the Cart' with the FSE added.
Short term demo's do not usually allow for the perfect Geometry Dial In.
