Isolation Feet Upgrade

Happy Holidays!
I recently upgraded my Ayre QB9 to its Twenty status and bought a Bryston BDP Pi. Everything’s sounds good but if I could slightly increase bass and warmth I’d be even happier. My thought is to replace the ASR power cable to a Cullen Crossover II and by adding more silver into the power cord, that I’d increase warmth that way. The second tweak would be to replace the Herbie's Tenderfeet but am not sure what would constitute an upgrade. I have read claims however that certain brand names will increase bass response. I remember the time I replaced the stock feet on my QB9 in 2011 and how surprised I was by the improvement in clarity and detail. Am I just chasing my tail with these tweak notions or can I really tailor my equipment into a slightly more preferable sonic signature. Price point is always a factor.
Any help is greatly appreciated, thanks!

Herbies Tenderfeet provide warmth (which I consider colouring the sound) and they also rob the component of deep bass extension and slam.

I use DH Cones for isolation. They're placed under the component chassis and require some type of platform or vibration free shelf. The different type of cones can provide levels of warmth, but all help create a open, transparent sonic signature.

Stillpoints are always highly recommended, I think they avoid adding any warmth.

I just discovered EVP's from AV Roomservice and am very pleased with their isolation ability. They impart no sonic signature into the music, they are as transparent as I've heard in my system. The bass comes through deep and tight.
 They can be placed under the stock footers or the chassis onto any surface.

Hi @goofyfoot , hope all is well. I agree with your plan, add the Cullen first. I have 3 Crossfires in my system now plus a Cullen C7 for my Node2i. All present open sonics with very good low-end performance.

lowrider, I mainly listen to classical/art music so altering dynamics may be preferable with popular music but will noticeable alter the natural balance of a piano, cello, etc...
The EVP website is definitely thorough but nothing is mentioned about price.

I listen to mainly classical as well; symphonic, quartets, quintet's, trios.
The price of the EVP's is there somewhere, I think it's $45 each. I'm using 3 under my preamp and will buy another set soon. I've replaced all my Herbies Tenderfeet.

When I mentioned how much bass is now revealed, it's because other footers I was using restricted or softened the low-end. With the EVP's and DH Cones I now hear what the engineer intended. They're not expensive and now I hear the dynamics that were recorded. My system was always bass shy. 
Now if i could only get the bottom octave without adding a subwoofer.

I found hemispherical isolation feet with a 20A Durometer rating.

Super Soft, excellent decoupling and vibration damping without having to break into your piggy bank.
