Bright Star Gemini vs Gingko Cloud Comparison??

I would greatly appreciate your sharing any information about the relative performance and merits of the Gemini (2 or 3) and the Cloud (10 or 11).

I have read a number of threads in Audiogon and several reviews in the high end press in which various elements of vibration control were discussed, including a variety of theories and DIY projects. For me, the most compelling theme that emerged is the need for a comprehensive system to control vibrations. The system should address isolation from floor/rack/shelf vibrations, as well as the reduction of both the air-borne and the component-generated vibrations.

Given that I am not much of a DIY person and given that the number of products in the market is huge and they use different designs and materials, I need help in determining a short list of comprehensive options to audition with my CD player and tube amps, all sitting on MDF shelves in racks which stand on a concrete floor. The mega-buck alternatives are beyond my budget. Of the "reasonably" priced units I ran across, the Gemini and the Cloud seemed viable provided that some mass loading is added to each. Any mass loading that reduces EMI/RFI (like the Little Rock 2 or 3) would be desirable.

Many of the products that do not address the isolation from floor/rack/shelf vibrations perhaps could complement products that do, and hence be integrated into a comprehensive system. I am open to other options for my short list that are reasonably priced and reasonably effective. For example, how can the Black Diamond Racing Shelf be made a part of a comprehensive system?

Finally, I understand that the resonance frequency is 17 Hz for the Cloud 10 and 13Hz for the Cloud 11. Does anyone know what is the resonance frequency for the Gemini 2 unit supporting a 50 lb mass-loaded CD player or an 80 lb tube amp?
