The Cart' Comparisons are not only reserved for the assessment of Styli, they are assessed to see how they compare to each other in the overall performance and what technology might be responsible for defining any differences that was noticed. It was only on the last occasion that the Styli were suggested to be included to see if a styli could be detected for having an influence, as there were Styli of the same Brand and Form used on two Cart's in the demonstration line up.
There are FG Styli available if one looks into work carried out by Cartridge 'retip' services, the Brand is being used. The same can be said for Two of the Cart's to be used in the upcoming line up, as they are not made any more and one of these is a bespoke rebuilt version, in the previous demonstration comparison session, not one of the Cart's in the line up was being produced when this took place.
My descriptions are offered on this matter only to inform that the attendees at a demonstration did not suggest and encourage the analysis to lean toward, that a Styli only was responsible for the performance differences being detected. It was felt that the overall assembly of the Cart' was most likely responsible.
Experiences such the above reinforce my own thoughts that it is prudent to be wary / aloof of the Sales Spiel attached to certain components used in an assembly.
I don't think I will be looking into seeing if a arrangement can be made for a comparison between a Ultra Fine Replicant 100 and the later version with the description as being the extra polished Ortofon Replicant 100, I could not even think where the improvement might be found in the extra polished version, but it does stand out in the Increased Font Size - Bold Text used in the Brochure containing the Sales Spiel.
