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’m also currently using Herbie’s steel cones with platinum disks under my Quad 2905 ESL’s and can say that doing so was a giant step up from the stock feet. The cost for most speaker isolation feet are crazy numbers.
My thinking is that dampening implies something else but I understand your point.
It's damping. A different word, therefore different meaning.

Either way, I'm still sold on the improvement they made.

AYRE and IsoAcoustics seem a natural, sonic, fit.

Happy Listening!
I run Cullen Crossover ll only and they are terrific.  I would replace with those, let them settle in and then attack the footers thing.  I’m still an equipment stand fan as opposed to footers.  

Iso Acoustics does seem on top of that niche.  I use Gaia ll on my floor standers and the Orea discs under some cheaper pieces with good effect.
