Boy, Oh Boy! Towshend!

Interesting...I wonder if the Nobsounds would have a positive, long term effect on individual components or fall into the same situation as your speaker experience. And pods are 1000x better than the springs. 


millercarbon would know best. But it sounded like components improved significantly with the springs. 

Sadly for me, John at Townshend just told me that at their shortest the Pods are 2". I need 1.5" so the springs are my only option for racked components. 

I can swing Pods under my sub but, well, I don't know what to do!

@vinylshadow - I don't know why you are not calling Peter at Symposium. He has one product called a svelte shelf that is really thin (I think a half inch or so) that might be perfect for you. It isolates and removes vibrations. He could be the answer to your problems, and if he can't, he'll tell you that. Rollerblocks are I think 1.3".

It was good to see a Foam used as Construction Layer for Isolation on the Symposium Products.
I have been using various foams with different compressive strengths for multiple years, these are the most impressive Materials I have used to date as a layer in a construction of materials to produce a support plinth.

I have a Pre Amp seatd directely onto a aerated highly compressible foam, to a point load the foam offers almost Zero Resistence to compressing.
This support lets the Pre' deliver a very clean and detailed presentation.
To date adding any other materials, to be used in combination with the Aerated Foam will show a smearing of the finest details.
If a air flow is not needed to enter the casing from the underside and the unlevel seating of device is not too off putting, this method is worth a investigation.

I will look into Symposium for rack component isolation for sure. I just need to get my thoughts together on the Townshend isolators first. But I think I have.
Speaker bars with pods under my Mezzo Utopia's and isolation corners under my Sound Anchors rack(thanks tvad). That knocks vibrations to everything down to 3Hz. Just need individual component isolation next.

My left Rowland Model 12 monoblock amp behind my left Mezzo and near my sub is on its own Sound Anchors amp stand with spikes. The amp and the connected separate power supply are both made of solid, machined alumunum. 30 pounds each. Do they need isolation? If so, I could remove the stand spikes and put each stand leg bottom on a Pod? That would be half the price of 4 isolation corners. I don't think amps vibrate on their own, do they?
Isolation platters under the turntables I'm not sure what to do there. Because of the dimensions of my 2 t.t.'s and their dustcovers, they may be the last thing I do.

Thanks to everyone who help me coalesce my pathway. Almost there.
