Soix, your reasoning is faulty. The substructure of the SOTA that sits on a shelf can be considered for our purposes to be part of the shelf. The platter, bearing, and tonearm are still suspended from springs. If you then add a base that itself is spring supported, you introduce an independent resonance to the system. The two different spring rates and resonant frequencies will likely cause problems
Sota Sapphire and Isolation?
Greetings, y'all! I should be receiving my new Sota Sapphire on Tuesday. I'm psyched! I currently have my Rega on a Gingko Cloud isolation platform. Since the Sota is a suspended table, will I need the isolation? Obviously, I won't know anything until I get the table setup, but my excitement is looking for any reason to engage with my new Sota. LOL. Thanks, y'all!

Interesting question. My intuition says springs on springs would make for interactions and very different resonant frequences which sounds like a bad thing. But I don’t know the physics in great enough detail to be able to say for certain and I have never tried it. The only thing I can say for certain is my sprung Linn LP12 benefited greatly from the Silent Running Audio Ohio Class platform I had made for it. That platform does not use springs. Great combo. Unfortunately it costs sbout the same price as the table. |
@lewm Ok, fair enough. But the shelf itself still vibrates, which is why people use isolation devices on a shelf, under a cabinet, etc. The question then becomes which is worse, the vibrations from the shelf or the potential resonance from the spring footers. That’s not knowable until you try, and since there’s zero risk again I ask, why not? |
The Merrill Heirloom TT has a spring suspension and I use the GEM Dandy 60 Durometer Decoupling Foot under my table , at the same time I use a wall mount TT platform to totally eliminate footfall vibrations from a wood floor . One can jump up and down or play the music loud with the deepest bass notes without issue . |
Do whatever you want. But do realize that the built in spring suspension of the SOTA is there to filter out all the stuff you’re talking about where it counts, before it can disturb the platter/bearing/tonearm/cartridge. I’m not saying it’s perfect, but adding a second independent spring suspension to the closed system can only interfere with its function. This is demonstrable with math and physics, not just a matter of my opinion. |
