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

From what I have read and experienced, mass loaded The  is better than spring loaded TTs. Someone correct me if I'm off base.

blueranger, you touched on an area of controversy.  There are two camps, high mass and low mass.  Linnies inhabit the latter.  Low mass usually goes with spring or other suspensions.  High mass usually goes with no suspension. "Better" is whatever choice you prefer.

I have a high mass diy teres and it benefited greatly from some isolation footers. You need some sort of acoustic decoupling
