@oregonpapa,

Thanks for your thoughts and I may add the ART9 back in at a later date. The hesitation comes from the fact that I have never experienced a cartridge that brightens up again after it has already smoothed out from the initial brightness.
@pani
I believe you about the ART9 but I am enjoying the Dynavector with Soundsmith ruby cantilever and re-tip quite a bit and it is a big upgrade from the stock Dynavector. If I had to make a cartridge recommendation I would say to find a used / broken cantilever Dynavector and send it to Soundsmith for a new cantilever!
I optimized my phono loading (it seems not too sensitive whether 0 ohms, 100 ohms or 1000 ohms).
My cables from tonearm to phono pre are short (0.5M), shielded and very low capacitance (19pf / foot) so I do not see any way to affect the sound to make it brighter.
VTA is a perfect 92-degrees. The only thing left is break-in.
@oregonpapa
your post summary of "new" vs. "broken in" sound is giving incentive to reinstall it sooner rather than later.
Stay tuned, this thread has been going on for a year and a half, i'm sure it will keep going for quite a while.
