Plus power cables
Footers don’t need power cables, or do they😒
But power cables do need footers, don’t they?
And sadly, after reading your advice to get the Auva EQ Footers and put them RIGHT UNDER the PowerZone feet I bought them and followed your instructions. I heard a nice change. I was sad.
And of course Tom, the REL supplied cords never left the bag they arrived in. I have $3000 upgrade REL High Level cables. I had to replace one after my bunny ate one.
I’ll edit my post: If you guys hear a big difference when you put your special feet under your REL Subs, let me know.
Yes, I remember the picture of the chewed cable. That was a sad day, but the bunny survived to chew another cable 
I’m amused. You guys got me good. (Is crow high in protein?)
As I was writing that unfortunate post, my inner voice was saying “Really?”. I have become complacent. Donald understands. There is a time when you are so happy with what you have built you just forget about rabbit holes. For me, having a friend with a system that is so very far advanced from mine, my last listen was more than I could take. I think there is only one room in the world where you can experience it. His. Try as I might there is no way I can duplicate it. Like me, he has a BACCH-SP adio. Other than that we don’t have a single similar component or cable. For me, being able to visit there frees me from trying to improve mine. It is what it is. When I visit @paul172 I think I could trade him even up for gear, but not the room it’s in.
It’s fun to dream about things one might do to get a step deeper into the journey to get as far as you can. I really think I am there. Two Stealth 2020 power cables for my PowerZone, my My Sonic Lab Diamond Signature cartridge repaired and returned, and replace my Vivid G1 Spirits with Vivid Giya G1 Spirits Cu speakers. Then I’m done. Oh, and that fancy floor standing, refrigerated super filtered DeGritter Fonoteek. They keep threatening to send me mine. Tariffs is the issue stopping them.
Anyway, carry on.
Ooog, almost forgot. My audio Guru, George Vatchnadze of Kyomi Audio, is replacing all his Sakra V17 LE cables with Sakra Golds. I believe I prefer the V17. Whew!
Sad is over rated, 
I removed the Stack Audio footers, and returned them as they were on a trial basis. They did help clean up the bass, mostly from elevating the sub. Everyone else’s results might vary, but for my system they helped.
Unused Isoacoustics Gaia II feet to the rescue!! Glad I kept them, as I put 4 of them beneath the base/feet of the Carbon Special and the sound improved again!! Happy times!
So many queries here.
Were the Rel’s runners removed for the Stack audio footers to go in?
Did you screw them in or just position the footers under the sub?
The Gaia feet look like they are placed under the Rel’s Runners, it this correct?
I just tagged you in a previous post.
I liked the sound the best when simply resting the the sub with the original base/curved feet on top of the Auva feet.
I have now copied that mindset using my Gaia II feet instead of the Auva feet.
I thought when you had the Stack footers placed under the sub but not screwed into the holes that you had removed the Rel runners to allow more room for the Stack footers.
I didn’t realize you had kept the runners in place.
When I get mine I’ll definitely remove the Rel runners and try both options.
just sitting under the sub and screwed into the sub base.
You are misunderstanding. I also tried the option you just described. Hence the reason for waiting for the correct screws that fit into the bottom of the sub itself without the REL base/feet.
Although not exactly apples to apples, but I had placed footers under my REL T/9x thus raising the REL up several inches - I found that adding space between the bottom of the REL and the floor created a boomy and less controlled bass response. I figured that REL has calculated the space optimally and increasing it as I did degraded the sound. I assume you did not find this to be the case with your setup.
I found just the opposite, that is less boomy.
I am not surprised given the different models in question. I am discovering over and over again that there are very few portable results from one system to another.
My previous PM to you was to offer you two sets, 8 total, of Stack #4 SW footers for your evaluation. ADP has already tried one of these sets with his RELCarbon. These sets include the appropriately sized bolts.
Short of purchasing (and, returning under their 60 day policy if you don’t like them) I thought having them would be the best way to answer your many questions. Just provide your address via PM and I will send.
@adifferentpaul, sorry for the confusion, it looks like from the photo you posted that the Gaia’s are sitting under the Rel’s own feet which is why I queried about removing the Rel’s feet to evaluate the Stack footers.
Doing this would also increase the height of the sub, and as already posted, Rel calculate the best height to raise the sub off the floor to get the best bass response so adding the Gaia’s underneath the Rel’s own feet would compromise that correct height.
I’m assuming the Stack Audio footers and the Rel feet are approximately the same height so substituting the Stack footers for the Rel feet will keep that same height and so preserve the best bass response.
Thanks for the photo, I was going to ask what the difference was.
The Stack feet will make the Carbon Special look
even more sleek and purposeful.
