Most suitable and effective isolation platform

You may want to take a look at the TMC, the platform under the Rockport turntables

all of those are awesome and some get pticey. I have SRA and I would dfinite;y add symposium to your list.

what is your flooring?

slab, elevated

wood? carpet, tile? etc?

are you looking at isolation issues of a large scale or more subtle resonance issues

can't speak for the other but love SRA

if you had troublesome floors you might check out a wall mount turntable shelf

just one word. Bungee cords.

Iaxelrod,

I'm sure you know that SRA is the preferred platform for TW? Jeff Catalano of High Water Sound is a dealer for SRA and TW. You should contact him. I'm sure HRS would work well too. I have a Raven AC and use a symposium Acoustic Quantum. It does a great job. Jeff sells those too but he would probably push you toward an SRA. If the Quantum is beyond your budget a Symposium Ultra would be a great choice too.

Have Fun!
