Having set up 100's of TT's when I was a high end dealer in the 80's, it became readily apparent to me that suspended TT's with the motor fixed were not speed stable - particularly noticeable on solo piano pieces. Some are worse than others - the worst I had were the Oracle/Pink Triangle with their very lossy suspensions. The major problem with the early Sota's were the PAPST motor board regulators which were unstable. Knocking these out and replacing them with a decent regulated supply cured much of the SOTA instability. Later SOTA mounted the motor on the sub chassis which is a much better solution in terms of loop rigidity between motor and platter.
My experience selling gear is that many folk can't hear poor timing and therefore it is of no consequence to them.
The SME addresses the issue somewhat by using a hanging suspension and the platter is stabilised to some degree by anchoring the bearing using a rubber O ring looped around the bearing and fixed to the chassis on the opposite side to the motor.
Here is a graphic example of what lousy suspension is doing. When I bought a Platine Verdier ( for a second deck, its way behind the Final Audio ) I set it up with the supplied rubber belt. The Verdier has a very lossy suspension. No matter how I set the tension, the rubber belt vibrated and jigged its way through the music. Removal of the suspension and replacement with fixed adjustable feet ( custom inserts with BDR cones ) eliminated over 95% of the belt creep. Of course going to thread drive ( I use surgical silk ) gets rid of the rubber belt compression issue.
Peterayer I have not heard the SME 30, but certainly the Verdier (with suspension still in) outperformed the SME 20/V in the same system, significantly more resolving and music had a much more substantial foundation. The original owner of the Verdier never listened to the SME 20 again, it was consigned to the office. Cartridges used in the evaluation were Lyra Helikon SL, Koetsu Rosewood & Soundsmith Paua in rotation. For your information the Soundsmith Paua was an outstanding match for the SME combo, providing a very musical system.
