Raul,
In the case of the high mass Final Audio that I have, I think the key attributes are speed stability. Most suspended table/rubber belts have wow and pitch problems on piano in my experience. I note that many of the high mass designs produced today do not have great power supplies - 20kg platters driven by motors/supplies that look like they couldn't spin a cornflake. As an example of the importance of power supply a friend has a Rega P9 - its key strength compared to the priced competition is timing. Interestingly many years ago when I got my first MIT Reference interconnect there was a bigger improvement using it in the power supply of the Final Lab turntable rather than between pre/power. ( FAR power supply has ac sine wave generator and power amp driving the motor ).
