Those resonance figures you posted are absolutely fine. This is not, IMO, a tonearm/cart resonance issue. That combination is used by many people with no issues. Now, if one is using the Universe without one of the plates, 5 grams may be too light.
I have no idea what you mean by low end preamp.
Doug's B&Ws do not pump in the least with almost every record we played. There were maybe 3 times over a 6-7 hour session that I noticed woofer excursion out of the norm. We have also mounted his Universe on my TP and had no problems.
But it sounds to me like you are getting to the issue. I think you're rack, or what is under the table, is the problem. The granite shifted the resonances up higher. I know because I also have granite under my table as the shelf for my sandbox. It sucks because it does cause smearing in the midrange. I use Stillpoints between my plinth and the granite to remove the ill effects from the granite.
FWIW, I can tap on my stand and hear it through the speakers. That proves absolutely nothing about how the table is performing, IMO. Well, unless one tends to tap their stand while they listen to music.
No offense, but who is Richard and why is he intent on proving your arm/cart match is wrong?
