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!

jerry, isolation will minimize vibration. My thinking is that dampening implies something else but I understand your point.
Townshend or Ingress/slate platform/inner tube or Solid Tech are all good options
+ 1 on the Cullen Cable "Crossover Series" power cable. Even more impressive when you factor in the price to performance ratio.

One option to the Iso Acoustics "Oreas" ($45 - 60 each), is the Iso Acoustics "Iso Puck minis." They come in a set of 8 for $99 (I just noticed that they are currently 25% off @  Audio Advisor); but, two caveats......

1) They are only rated @ 6 pounds each (component must be < 24 lbs)
2) They are 40% smaller than the Oreas; so, they'll only fit smaller sized footers.
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.
