Any suggestions for the best form (on a budget) of vibration control for a power conditioner? Vibrapods, Vibra Cones, Ceramic cones, etc.?

Who knew? How do you measure the vibration?
Whether or not you can observe a thing depends upon the theory you use. It is the theory which decides what can be observed. - Albert Einstein
I've tried a lot of DIY vibration control--brass, wood, cups, ball bearings, brass ball bearings in combo with wood or brass, magnets, inner tubes, pumice, magic eraser--eventually I came to realize that even though it's fun to experiment, it's also satisfying to not have to strain my ears to hear a very slight difference.
All this led me to my own personal caveat that you need two things, 1) sensitive hearing and 2) sensitive equipment--if you don't have both forget about hearing much difference (this may be why certain people claim that if you can't measure it, you can't hear it, as they may lack both)!
Eventually I bit the bullet and went with Herbie's products (I do have some vibrapods) and realized sometimes leave it to the professionals. Then I bit another bullet and spent the money and am heavily invested in IsoAcoustics products. These made a HUGE difference and I now use them under every piece of equipment as well as my speakers. Their Iso-pucks are, I think, about $100 for an 8 pack which is a good deal. I have not A/B'd them against their own Orea product line which I have, and the Orea's are more expensive and more solid/heavier.
So, if you have sensitive ears and sensitive equipment and don't want to spend the money, try DIY. If you have the money, or ask Santa for IsoAcoustics go with that. Good luck!
I use the same kind of vibration control for a power conditioner and regenerator as for any electronics. They should have the same reaction to vibration since they use the same kind of devices inside. My feet are fairly rare called Pon-Toons, specially selected plastic cylinders on the sides with stability bases. If you have a favorite base or feet for electronics, that's the first thing to try.
They had a huge affect on my CD drive and noticeable affects on any electronics including the regenerator(all my low level devices) and conditioner(my amp) cleaning up the sound and making it more focused but of course the affect varied depending on the device being supported.
I use something like this. In my case the board rests on the floor and the power line conditioner right on top of it.

Very similar approach here with the exception being a maple butcher block.
Maple being a well-regarded tonewood is probably a better choice.

Joe....never did any extensive research aside from that particular piece was simply left over from a maple butcher block rack project. I also have numerous bamboo shelves/platforms under various components. Both of these woods work for me.
No conclusions on my part having tried little hunks of myrtle, Indonesian ebony footers, and a slab of bamboo as a support. They all do something mainly in small degrees at least as I've used them.
Also BDR pyramids and pucks which I tried first of all, then Mapleshade brass footers, Herbies squishy feet, HRS Damping plate, and Svelte Shelves. I keep going back to the Mapleshade brass footers and the Svelte Shelves. Maybe my aged ears find a little boost in the treble helpful but honestly I liked the brass footers 20 years ago so it isn't just that.
And so it goes.

You could try various types of wood under it, either blocks or a small board. Try Herbie's SuperSonic stabilizers. two usually does the trick.

If you wanna first try something ultra cheap, you can experiment with Diversitech EVA pads. They work really good under my subs. They are not audiophile products, but a power conditioner isn't a preamp ;-)
When I listened to similar pads, rubber, cork rubber it degraded the sound. These pads are described as being much better for vib damping than rubber cork rubber so it does indeed look like they might be worth a try if one doesn't want to get the wonderful EAR C-1002.
"Description
EVA (Extreme Vibration Attenuation) is the latest generation in vibration dampening technology. In the most severe vibration extremes, testing shows the EVA pad outperforms cork and rubber by greater than 3:1 and outperforms competitor's "waffle" pad by greater than 8:1! The enhanced performance comes from the special composite foam center which is structurally more sound than cork. EVA is not affected by oils or chemicals that can break down cork and is much more effective at vibration dampening than solid rubber. Designed to withstand 50 psi. Choose EVA to get the best of both worlds!"
Denied facts are still facts.
Well possibly, I haven't heard the EVA pads under electronics, and I probably wouldn't try, but I believe if indeed a power conditioner responds well to vibration control devices, there still isn't any audio signal traveling through it, and you probably have more options than for a DAC or a preamp.
(I seem to recall however someone using the EVA pads under his electronics and liking the results, but...)
they certainly are cheap enough to deserve a try!
EAR C-1002, all else rubber wise is boat anchors. If you want to get more elaborate you can do the brass, wood, rubber paradigm. 5/8in brass acorn nuts, yellow poplar and EAR C-1002...
Denied facts are still facts.
