High mass vs Low Mass Turntables - Sound difference?

I like suspended tables which are placed on butcher block shelving mounted in an alcove in the wall using lots of space frame structure to prevent bass energy induced room vibrations from perturbing them.  This seems to work well.  I am using a SOTA Sapphire and a VPI HW-19 Mk. IV and they both work very well with this set-up.  They both weigh about 50 lb.s and the wall-mounted shelving weighs another 100 lb.s.  Not sure if this qualifies as light or heavy weight....I'm sure there are much heavier turntables than these. 

WRT light weight suspensionless turntables, I've never heard one that could reproduce deep bass well or resist structural vibrations.  I include the Regas and VPI Scouts in this category.  I've owned them both and couldn't wait to get back to the good 'ole HW-19, the most consistent (and underrated) turntable on the planet.  By the way, the quickest way to judge turntable bass performance is to get a CD of the same recording as your favorite vinyl and compare.  CD's have their problems, but true bass is not one of them.  If your turntables bass does not sound like the CD, your turntable has an issue.

Geoffkait " What a load of hooey."
Wow, is that the pot calling the kettle black.

+1 My experience exactly. Geoffkait doesn’t seem to know what "plastic" is and that Vinyl and acrylic are forms of plastic. He clearly thinks that the  majority of light weight turntables are made from something other than plastics. The amount of "hooey" on audiogon seems be directly proportional to Geoffkait activity.

Another stalker joins the party. Make that two stalkers. Shadorne has a little difficulty with reading comprehension or so it would appear. Of course he might be pretending to be slow, it's difficult to say for sure.

I didnt do nothing. Just responded to your ignorant post that was "stalking" my initial post.
