Saint- The HRS platform is fine, but as I indicated, it really has less to do with isolation than just providing a platform for my big Kuzma table, which has no plinth and needs something to mount it on.
The Grand Prix stuff was great in its day, and I still use it, but do replace the sorbothane pucks every six months or so, not a big deal, but I get where you are coming from.
I think if I were starting from scratch I'd look at some some basic constrained layer platforms and well built shelving, furniture consoles or other well-built furniture that is not necessarily 'audiophile approved,' and do the isolation or decoupling separately. That seems to be the route several people have taken- folks who could conceivably buy anything they wanted to enhance system performance. The advantage is, you are not stuck with a spendy 'rack system' that may be last weeks' flavor after a couple years. (Though admittedly, things like Stillpoints as separate decouplers get pricey pretty quickly when you are doing a bunch of components). There is also a pretty well made wooden rack by the Box Company that a few people on the Hoffman forum were discussing. I think this is made by the same guy that builds the cabinets for DeVore speakers, so he may be local to NY. Worth checking, anyway. (It is not 'high tech' but looks pretty nice and you could probably add some additional platforms or decouplers as necessary).
I saw that you pinged Myles on his system page- I'm not sure he visits A-gon that much. See if you can't find an email for him via Positive Feedback Online. He's usually pretty responsive.
