Break-in is a well-documented effect especially with speakers. In my operating manual for my speakers, MartinLogan specifically advise a break-in time of the order of 70 hours or so at 90dB SPL for the crossover components and bass driver. Prior to that level of use, they warn of a very light bass with respect to the rest of the transducer range.

This would raise the question of how a manufacturer could confirm if a product met specifications! The break-in recommendations suggest that the specifications are not something that a "mint/never used" speaker would be able to meet and that the specifications are inferred from the design prototypes and an assumed characteristic when "new" and unused.

Incidentally, was your OC9 supplied with a calibration trace? I don't know if it is a default thing or not. My OC9MLII had one.
If this were the case, then with respect to cartridges which are calibrated and tested to pass a specification (given that the better cartridges are supplied with a response trace), I would expect them to sound "correct" from the get go with a possible restriction on the maximum signal amplitude that could be tracked for a given VTF within the recommended range.

What characteristics would you think could give rise to the sonic effects you noted with your OC9 that perhaps would not show up with a response trace? I would expect that any anomalies on sonic presentation must surely be due to an interaction with the damping elastomers and suspension causing a mechanical impedance that is not matching with the preferred design values. If this were the case I would have thought that these anomalies would leave a signature on the frequency response trace.
