elliott's Ventilated Equipment Surround / Stand

Those are a good choice of height and you've got temperature covered. As I said before, I like it. Good luck moving forward.

Thanks for the encouragement.

Tabletop, in/on a rack/shelf, anywhere that makes sense.

They can make combos of equipment look organized. I've got two medium height black maple ones side by side on top of my low glass top rack. Then a deeper piece of glass on top of them, my deeper heavy TT on that, at a very nice operating height. Importantly, I can pull/slide any unit out without moving anything above. And I left some space for Donna's Plants. 

Two units stacked within one medium height unit: My 1/2 height short depth Chase Unit on top of a 1/2 height full depth CD Changer. (not a happy look when in open sight). 

Amp over Preamp is Mahogany, on a separate wood cabinet. It must be level if something heavy is on top, to prevent potential of sideways creepage. Note: Vintage McIntosh units have Trim Controls, on the top, the unit must be pulled forward to adjust them. This design, just slide the lower unit forward, or, take it fully out, test all it's tubes, never disturbing what's on top. My prior McIntosh MC2250 weighed 80 lbs. I have a 3rd torn meniscus in my knee from moving it from a low shelf. This would have solved that.
 

It seems like an elegant/simple design but probably not for anyone looking seriously at isolation

slaw,

Thanks for the compliment.

I never considered Isolation, just feet/spacers that won't scratch anything or slide around easily.
