Best Isolation HRS? SRA? Zoethecus? Symposium?

J-badov - It appears you have your concepts of isolation and I have mine. Nothing wrong with that and I agree, no need for pissing contest. There are many ways to skin a cat.

I designed Nimbus platform, a 6 DOF sub 1.0 Hz device about 8 years ago. Nimbus is the world's only single air spring iso stand. For ballast for the Nimbus I use steel - as you say: inexpensive and well-suited to the task. Depleted uranium would be my next choice :-)

Hey Geoff, I must agree. Cheers and Happy Holidays. Sorry I was not trying to knock you or anything else. Just a good lively debate. Thanks for keeping me on my toes.

Depleted uranium is a great idea, it may also have many other sonic benefits. ;-)

TBG, Kuzma uses a silcone, fluid damped isolator in their Reference Turntable to excellent effect. I've not used another fluid (apart from air) system.

"...or you could partially fill the bladders with fluids as Kworks does. Filling the center with sand would also lower the resonant frequency.

Depleted Uranium is nothing but regular Uranium with a slightly higher U238 to U235 ratio, and is a healthy source of ionizing radiation. Your gonads will love you for the extra attention to their well being!
Depleted Uranium is used in weaponry not necessarily because of its density, but because it enjoys a combination of 'desirable' properties: density of 19.50, extreme hardness, high flamability, and high toxicity. Are you sure you want some of it in your living room?
Lots cheaper, safer, and for our purpose just as hard and heavy is good old Tungsten (W), with a density of 19.25, or if you want to be exotic, try Iridium (Ir) with a wapping density of 22.6. Please let me know if any company introduces an isolation platform ballasted with depleted Uranium. I'll make it a point to shop where that brand is not carried.

Hello all. I am taking precious time away from my wife's WONDERFUL relatives to read the posts. I love Guidocoronas.
Chuckled is an understatement. Love the Kuzma Reference TT/ Airline Arm & also the Vibraplane, but I will only spend the huge dollars required on Uranium tweaks if we can ship directly to the OUTlaws to try before I buy. Let me know.
Best Regards, Nick.
By the way, what ever happened to Adog??
