Footers Under Power Conditioners?

I think it should be a positive tweak, albeit subtle.
I recall reading how a Core Power Equi+Core would be improved by using better footers-

I'm using Herbies Tenderfeet under an Equi=Core 1800 and it's an improvement over stock. It is subtle and I think I can do better than the Herbies.

Ozzy, I believe power conditioners with large toroidal transformers will benefit from some type of footer or platform. Using  Herbies Tenderfeet helped  mine, will try the EVP's next.

I didn't notice that. I have them under my preamp chassis. It uses an EI transformer and is very heavy on one corner. I spoke to the manufacturer and he said to place the EVP's so that all three are evenly compressed.
He asked me for a photo and suggested better positioning. So, I have 2 of them close to the transformer and one on the lightweight side of the pre.
I couldn't use traditional positioning but it really sounds great. 

My EquiCore is on the floor so I may need to use the foam covered EVP's so that they grip the PC.

Ok then, that is one heavy SOaB. 

Ozzy, thanks for your replies. This is really a case of YMMV.

In my case, the EquiCore has a massive toroid, so I'm thinking I should treat it like a SS amp.
Don't know about the Niagara.

I see you use Iso-Acoustics in your system. Don't they work on the same principle as Critical Mass?

OP, where is your Audioquest located, floor or shelf?

From what I've read, something as soft as a Tenderfoot would tilt the sound far too downwards so maybe these would do something less offensive.

I've replaced all the Tenderfeet in my system with other types of isolation/vibration devices. I can now hear that the Herbies dont articulate the midbass and they soften the bass attack. 
I'm very impressed with the AV Roomservice EVP's under my preamp. The presentation is now neutral with tight bass. Like Ozzy, I'd like to find new footers for my 60lb. power conditioner.

The AV Roomservice EVP..

Have you noticed any additional improvement in the Niagara now that the CM's have settled in?

I'm still looking for something to go under my conditioner. I now have a Core Power EquiCore and DeepCore stack, about 80 lbs.
I still believe the right footer will benefit the sound of a power conditioner. But, the CM are beyond my budget.

@ozzy 
From what I've read, the Niagara is the new gold standard in PCs. I'm committed to my Core Power stack financially and for the DC blocker which I need in my system. I should add I'm happy with the results.
I'm going to give the Isoacoustic orea a try based on many positive comments on the forum. They can also support heavy weight.

@markush

I didn’t try them. Once i discovered EVP footers from AV Roomservice, I’ve added these to my components. They’re not cheap, $120 apiece.

So I cheaped-out and put Herbies Tall Tenderfeet under my 2-box PC.
