I forgot to mention that I’m guessing that upgrading the power cord might increase bass response itself?

Herbies Tenderfeet provide warmth (which I consider colouring the sound) and they also rob the component of deep bass extension and slam.
I use DH Cones for isolation. They're placed under the component chassis and require some type of platform or vibration free shelf. The different type of cones can provide levels of warmth, but all help create a open, transparent sonic signature.
Stillpoints are always highly recommended, I think they avoid adding any warmth.
I just discovered EVP's from AV Roomservice and am very pleased with their isolation ability. They impart no sonic signature into the music, they are as transparent as I've heard in my system. The bass comes through deep and tight.
They can be placed under the stock footers or the chassis onto any surface.
I listen to mainly classical as well; symphonic, quartets, quintet's, trios.
The price of the EVP's is there somewhere, I think it's $45 each. I'm using 3 under my preamp and will buy another set soon. I've replaced all my Herbies Tenderfeet.
When I mentioned how much bass is now revealed, it's because other footers I was using restricted or softened the low-end. With the EVP's and DH Cones I now hear what the engineer intended. They're not expensive and now I hear the dynamics that were recorded. My system was always bass shy.
Now if i could only get the bottom octave without adding a subwoofer.
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.
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.
+ 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 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.
BTW, I'm also a goofy foot.
I built custom equipment racks. Used 4" HD EVPs to support the rack and isolate it. Each shelf is 1.5" hard maple butcher block supported by four 2" HD EVPs. Tighter, clearer, deeper bass is the main improvement. Darker backgrounds, clearer mids and overall more tonal accuracy/presence are additional benefits.
I don't use subs but Jim Smith of Get Better Sounds reports that using 4" HD EVPs results in a big improvement.
I moved to Herbie’s Tenderfeet under my Krell Digital Vanguard over the summer. It was a worthwhile upgrade. After a few months, I decided try the Iso Acoustics Orea Indigo’s under the Vanguard. The upgraded sound was very noticeable and I would 100% make that move again. Just an immediate tighter, more enjoyable sound. Very worthwhile.
The Tenderfeet are now under my office amp.
BTW - Recently I decided to try the Iso Acoustic Gaia II’s and carpet disks under my Vanderstenn 2ce II Sigs and was disappointed. I was expecting the same sort of improvement from an already excellent in my mind sounding amp/speaker combination. Turns out that the Gaia’s really just sucked all of the dynamics out of the sound. I gave it a couple of weeks trying to tweak the placement of the speakers. Eventually gave up and replaced the Gaia’s with the original spikes and there was no question that this was the right choice so I sent the Gaia’s back. I do not doubt people who see an improvement from them - just in my scenario it did not work out. I am using the Vandersteen stands/bases filled with sand on a carpeted floor over a concrete basement.
The Iso Pucks are cheaper than the Oreas and may be what you need.
The guys at musicdirect.com are great to deal with and try all the products first hand.
All the best,
Yes, I have a set of the Cardas Myrtlewood. When used under a component, they present no colouration. However, they are highly influenced by the surface they sit upon, IOW if the shelf or platform is a hardwood such as bamboo then the sound becomes lean and the highs are emphasized. If they're on a soft wood, the sound is warmer and the attack is slower.
I tried them under different components and was never happy with the sound. I don't think they drain vibration or provide isolation. I moved on to other footers and maple platforms.
lowrider, I’m beginning to realize that different feet, under different components, will likely render the best results. I’d certainly like to purchase various types of feet and try them out in various combinations but that’s not economically viable. Testing cables and phono cartridges would be the similar.
