What's the best isolation system?

I have tried several things from Iso-Bearings to Vibropods and have had the best results with AQ Sobethane Feet under my turntable. On my CD players I use the Paulsen Platters which are no longer made bu are in breif a platter riding on apposing magnetic fields. These seemed to enhance the bass on my CD and DVD players

Symposium is the only way to go.

Yo Lugnut! I'm pretty much on the same page with you about concrete slab construction, spiked stands and 3/4" MDF, but will add aluminum cones work better than brass or stainless on concrete....I moved into the new old house a couple years ago and figured I would have a lot of trouble with the 3/8" glazed in place windows behind my system and that just has not been the case at all....As far as very sensitive items like transports (the clock) and turntables I really like an active air suspension, but these aren't cheap.....I'm sort of in the cone business as an outgrowth of the preamp business so I have had access to a machinist to make up various cones for me of aluminum, brass, stainless and combinations with Delrin, a machinable hard plastic....On concrete slabs aluminum or stainless/Delrin combination works best and on pier and beam flooring brass seems to be the material of choice....No set rules for any of this other than active air suspension which is the cat's meow....

Audiopoints and the sistrum racks are great. They have audiopoint spikes with shelves that all have adjustable spikes. The metal support rods are filled with microfil miniscule metal bearings that all serve to transfer vibration into the ground. audiopoints.com. Concrete floor is great but if you don't have that try using a subfloor cork subfoor combo with fiber carpet pad and of course carpet.

Rcrump,

I really am interested in your comments about the points since I'm in the process of building a new equipment rack. Would you say that aluminum points for a rack would be the way to go with a mild steel frame? Do you think aluminum would be a better material for the frame itself? Also, my comments about glass were limited to shelving material. In no way was I being critical with whatever works. Also, a world without windows would be an ugly thing, indeed. It doesn't surprise me that windows behind your system have little effect especially if you have floor standers out in the room as is the norm. Is there an aduible difference between the drapes being open and closed? Just to clarify on my turntable recommendations; what I described works extremely well with suspension turntables. I understand that suspension-less tables want lots of mass.
