High mass vs Low Mass Turntables - Sound difference?

I recently heard the Rega RP 8 and was very impressed.  I actually think it is a better table than say the VPI prime and Classic.  I believe the scout actually sounds just about as good as either of these tables.  The problem with VPI is their arms.  Unless you use a moving magnet or moving iron cartridge, you will run into tracking issues because there is no real anti-skate mechanism with their arms.  Not good when you are running a low output moving coil cartridge that magnifies everything so much, you need an arm that will not fight the tracking of the cartridge/stylus.  I think the founder of VPI does not really believe in anti-skate.  Well, i guess if you use an aries with a 12 inch arm that probably helps a little.  But if you do not have a 12 inch arm, you NEED antiskate.  The Rega tracked much better than the prime or the classic and really digs into the grooves.  Amazing table for the money.  The only thing I do not like is it is too plug and play.I am not sure their cartridges are the best and I believe their arms are worthy of much better.

Tzh21y, you and I are hearing the same thing. The Rega has this incredibly clean, detailed and fast sound. 

I never liked the VPI arms either and they are a pain to setup.

Also the VPI drive system always has a bit of noise as you can hear the round belt riding in the crown of the pully unless they changed that I always thought that was a design difficency of that design.

I will disagree with you on your last part, the new Rega Alpheta 2 is a remarkably good cartridge, it is way better than the 1rst gen Alphea.

For the first time Rega is actually getting raves on their cartridges. 

The exact and bias do sound good for the money but lacked some of the midrange bloom of some of their competitors.

The new Alpheta 2 and the new Anima cart are really quite special.

Let me axe this-
which design is less likely to be affected by environmental vibration?  I am guessing it would be the high mass designs because I own one and it is never affected by vibration. 
I see lots of people with Regas that need to mount them to the wall.     

I may have heard an earlier version cartridge.  I think a benz on the RP 8 would be special

@avanti1960 ,

Right on man!

This is the main issue here. Not High mass vs. low mass.. it is first and foremost how any TT is decoupled from it's environment!
