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, 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.




 Isoacoustic Oreas did wonders for me. Tighter focus, improved detail and extension at both ends. Better tone and separation along with an almost 3D sense of sound emanating in all directions on better recordings.

All the best,

The Isoacoustic Oreas might be a nice addition to my ASR Emitter II amp as well as my modified Thorens TD160. I’m thinking the EVP’s for my DAC however.
