Townsend springy platforms for my Sasha 2s, springs not ISOA GIAS, HRTs for electronics???

I noticed a lot of discussion recently about springs as OPPOSED to spikes, Iso acoustic GIAS or HRT supports. I may be way late to the party, but in tracking this down I discovered the company Townsend. The engineering may be complex but the working concepts are pretty easy to grasp, but do they work?  The company's suggestion was to remove my GIAS under my Sasha 2s and additionally add three platforms for my electronics, two under my ARC REF10 and one for my dCS Bartok. A 5K tweak is a lot but not out of the question. After all when a pair of Cardas interconnects is $4250, 4 to 5K for proper support for five components does not sound unreasonable if they make a significant contribution. Does anyone have experience in what I might expect these products will contribute? The pitch is to buy it all to get the best price, but is there a progressive implementation that makes sense? The company rep suggests replace the GIAS first, then source, preamp then amps. I can't wait to hear from the collective as while spring suspensions have been around forever on turntables, the trend I was aware of has been toward ridged coupling for speakers. Even my old Krell KSA  had factory spikes for the footers. Old dogs CAN learn new tricks if it sounds better!
