High mass vs Low Mass Turntables - Sound difference?

Without getting into the relative merits of the two types of tables, one additional factor to take into account is isolating the high mass table. My Kuzma XL is approximately 168 lbs, and the HRS base for the various turntable parts to sit on is easily another 50-60 lbs. The HRS alone is not enough to isolate the table with springy wooden floors. Hanging this monstrosity from a wall is not so easy either. The cost of those high grade isolation bases - like a Minus K or whatever-- adds an additional cost. Though I prefer the sound of the XL to the smaller Kuzma Reference I owned previously, that table --which was no lightweight itself- had a suspension and was pretty much set up and go, right out of the box. Something to keep in mind for those without concrete slabs. 

That’s a really interesting point since isolating an object on a mass-spring system actually reduces the mass of the object by a significant amount. Kind of your own private anti gravity machine. Also, one would have to analyze air bearing/high mass platter turntable like Verdier and Maplenoll and Walker to figure out just how they fit into the whole high mass vs low mass spectrum. I had an air bearing everything Maplenoll with special 50 lb platter isolated on a special version of a Nimbus sub Hertz platform. That turntable set up did NOT suffer slowness or any other malady one might ascribe to high mass turntables.

Corvette vs Lotus?

Both win races but driving them is a hugely different experience.  I think it comes down to personal preferences.

I don't believe there are "absolutes" in the audio hobby.

Pretty sure the analogy doesn't extend to Sumo wrestlers.

I’ve owned over a hundred tables just cause I like to play with them .
Most expensive was a Linn 3k job .
I tried to figure out what was best but I got so tied up in music I forget to take notes .
All I know was Sansui 929 was the most beautiful one and the one I wish I still had and for that reason .

The only absolute Is God .
