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!

@astolfor so the cheapy Nobsound spring discs are almost as good as the expansive stuff?

@gochurchgo yes they will take you almost there, but the step up to the expensive stuff is as noticeable as going from no isolation to the disks of silence and Nobsound.

The most benefit after the TT was under the speakers and subs, that was a big step.

@goofyfoot if you try them make sure that you play with the space between the pucks. In my case anything more than 2mm was horrible, then I tried 1mm-1.5mm, and we were able to hear the difference.

The gap is room dependent as each room/system has difference resonances. 

Just for fun I ordered 2 sets of Amazon “spring loaded speaker/subwoofer” feet. I decided to put them under my Heresy 4’s, 4 springs on the rear and 3 on the front.

 

obviously higher and that changes how they sound but the imaging seems much more locked in. Could be placebo. I’ll listen all weekend and then pull them out and see. FWIW I’m on a concrete pad on the ground floor. Expectations are low but just having fun.

 

i made an error in that I didn’t listen without subs so I will have to do that before I removed. Kinda made I forgot.
