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

Yeah, but there are a lot of turntables that are low mass and without suspensions.  Some companies, like Rega, believe this is the way to go for sonic reasons and others just do it because it costs less and involves less setup problems.  Every camp has its followers.  

@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.
