Boy, Oh Boy! Towshend!

Leverage will work(a dolly) under the accessible front corners and left rear corner pretty easily. Getting leverage to the right rear corner will be super tough. I wonder if I can get a car jack to fit. There's about 1.5" of space below the base bars....I only need to raise each corner about 3/4".

Even if you don't have a trolley jack to lift it, I recall it was plenty heavy (I haven't scrolled back up to see) speaking of leverage, maybe you could use a simple bar and block with the help of a friend to lever it up, chock it, get your isolator under it and remove the chock?
Be sure and if you do use some lever bar with a block as a pivot point, use something soft not to scratch the underside of your pretty and expensive rack.

Thanks for the air shim link! wow. That would be perfect as there is barely enough room even when the rack is slid out a bit for me to get back there. The rack itself is 300 pounds so I'll need to remove the 100 pound center speaker first. But lifting a corner might be easier and I just need to lift like 3/4" I'm psyched.
As far as my speakers, no room for podiums so I'll get the bars. I'll tilt the back forward, remove the spikes, and put one bar under and then tilt the speaker backward, remove the front spikes, and put the other bar under. This way I can keep the position the speakers are in now. But those sliders are so inexpensive I may get them just to have handy.

I am going to ask John at Townshend how tall his pods are as I only have 1.5" for certain components. But honestly, would the Nobsound springs give enough vibration control to individual components? Lets say 75% of what the Pods would do?

I don't know if I want to spend $1100+ on speaker bars for my sub.  Springs might have to do. 

Buying isolation platters for my turntables that already have suspension systems.... Gotta think that one over. 

Pods would raise the height of the tables. Had custom acrylic dustcovers made for both. They might not fit over all the way down with pods. And 4 pods on 4 pods seems unstable. 

Maybe. Maybe not.

Each air shim is rated for 300#. So, use two. Done.

Great idea...I’ll need to swing the rack out 2 -3 feet to change components etc and to mount the isolation corners so I can use those sliders on the pods so I can slide the rack along the tile and grout lines and back against the wall. Awesome.
