Just an observation here, but????????

Buy one of either, then jump up & down as hard as you can right next to it while playing.  The one which is affected less is obviously the more isolated (hence better at isolation) than the other one.  

I believe Linns & Thorenses are still almost unbeatable in terms of price/performance.

I favor suspended ones.  Its like a car.  Would u feel the bumps in a car with great suspension or with great mass but no suspension ?  The WHOLE mass resonates.

If you don’t have the ability to get an absolutely massive rack w/ isolation platform and place it on a solid enough floor, then I think a proper spring suspension is your salvation. For “cost-and-obstacles be damned” folks, the former is better.

i have both. The heavy no-suspension table goes on a Critical Mass Systems rack. The sprung SOTA goes on a much cheaper Salamander.

@cakyol - although the Linn has springs, it has almost zero isolation from footfalls.  Believe me.  Unless you're using concrete floors or some other unshakable surface, wall shelf mounting is a must.  I thought they were isolated too, until I got one.  Look at it the wrong way and it jumps - if you have springy floors.  

The Townshend Audio Seismic Pods provide the isolation springs do in a suspended-subchassis design. Put a set of them under your non-suspended table and you have the best of both worlds.
