SRA VR vs. Ohio

I'm on the verge of investing in some vibration isolation platforms for my system. I use one digital box, a two chasis tube pre, mono SS amps, and speakers that have an outboard bass control so I would need 6 pieces in total. That would be some serious $$ if I went with all Ohio Base plus. I'm sure there are plenty out there who own the VR series and the Ohio Plus, so my question is, what differences do you notice between the two, and what components do you use with which?

I'm thinking about starting with all 6 VRs initially then trade up to a Ohios one at a time, starting with the mono amps, in a year or two but welcome any comments or suggestions.

Thanks.
