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!

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.

lowrider, thanks! Patrick first made me a pair of jumper cables back when the Red series were popular and then did surgery on a couple pair of Hi Diamond cables. His work is solid. I can’t believe his prices are so reasonable. I’m unable to make the purchase right now but it should be soon. 
I did see the prices on the EVP feet, pretty reasonable also.

Nice QB9 upgrade! The AYRE Twenty Series is very special.
Good to read that these products are responsive to feet upgrade(s).
I am looking into IsoAcoustics myself.

Happy Listening!

Jafant, yes, I’ve been happy with my Ayre since the day I bought it and Ayre offers great customer support. Why the IsoAcoustics?

Jerry, the Black Ravioli look similar to the Herbie’s Tenderfeet but assuming there’s a difference in sound.
A difference in price too.
Black Ravioli's effect is one of damping as well as isolation.

My notes at the time (August 2019)
"Put the Black Ravioli Pads on last week.
A set of 4 each for the Dac and Dac power supply.
A set of 4 with the amp.
It bought all the changes I've made [over the last 18 months] together.
Synergy, I'd call it.
Really enjoying the music.
Seems that was what I was missing.
My cynicism has disappeared. BR Pads work."

Bought four Black Ravioli Big Pads for the amp (July 2020).
What an improvement.
More depth and detail.

Honestly, I was a cynic regarding isolation pads.
Thought it ridiculous to spend that amount.

I'm now a convert.
Money well spent.
