You lowered the noise floor quite a bit, so it's expected that you will get a much more palpable bass experience.
Well done!
Now ... can anyone get Mojo to behave?

Hey truly Craig...I am well-behaved. I have a glass of Bordeaux in one hand and a beer in the other while one of my three lady friends is stuffing grapes and cheese into my pie hole in my romantically-lit living room. Harry Connick Jr is crooning out of my audiobytes and my cheap but highly modified Sony sub is filling in the lower end quite nicely. Are you jealous dude that Slim and I are getting the gut punch (disco fever) mode in our 800s? We also have a continuously variable phase knob. Hee hee...

Mojo is on his own, I am the new low noise floor boy
I actually am leaning towards isolation, not noise. I think that the base of the TT was sucking the low frequencies out of the platter. The grease added in a layer of isolation. The problem with that is the grease migrates out and needs to be replenished.
This is where Clear Audio German Engineering might be on to something. They use magnetic suspension so that the platter is floating.

It just came to me.... I have it and I am not going to spill the beans, as this needs to be patented.... I know how to isolate the platter and boost all ranges!

I love continuous phase, I want continuous variable crossover

"Oh Slim...you want it all!"
That was my friend, Lily.
LOL!

This is where Clear Audio German Engineering might be on to something. They use magnetic suspension so that the platter is floating. In analog, isolation is low noise. Sound is nothing more than vibrations, right? Isolate to get only the vibrations you want to get through, and it is low noise.

Craig, maybe I am not thinking this through well, but what my thought was is that isolating the part to reduce the noise might be different from the idea that certain frequencies may not even be present due to absorption vs. being masked. Sort of like coatings applied to reflective materials to absorb radar so that it doesn't bounce back.
If the platter is 'hooking up' with the base of the turntable due to coupling, these certain frequencies are being drawn down into the base vs. freely passing to the diamond. Not sure if I am making any sense. But I am also not sure if this is different from inherent noise masking.
I am trying to think of this in a similar fashion to the "noise floor" of a radio receiver. If the noise floor is greatly reduced, you can hear weak signals which otherwise do not appear to be there. The signal is there, you just cannot hear it over the noise. But what if that signal was sucked up by something like a change in propagation. It's still out there broadcasting, but its being diverted by atmospheric conditions; and even if the receiver is maximized for an extremely low noise floor, you cannot hear it.
Maybe we are saying the same thing in different terms.

We are. All the isolation you are getting is eliminating analog noise from your turntable. Picture if the turntable was in Ian's Anechoic chamber, feeding the preamp into your room. The noise floor outside the turntable would be almost nil. Another way to think about it is this: the turntable produces a very small analog signal that has to travel from the cartridge to the phono preamp through the wiring. Noise can be introduced through electrical issues (so we ground) or through outside analog signals (vibrations from the platter, warped records, feedback from subwoofers ... all can have an effect, and all are noise, even infrasonic signals). Expensive turntables go to great lengths to isolate from all these outside noise issues.
