In Reply to: RE: DIY Carbon Fiber Disc Footers posted by Duster on August 02, 2016 at 17:45:21
When comparing Black Diamond carbon fiber cones , which I think won a product of the year award, to 5/8 inch solid brass cap nuts the small brass cap nuts bettered the CF cones, and the difference was yuge, believe me. I agree with Pierre at Mapleshade on this one. Brass Trumps carbon fiber, this is of course is IMHO, YMMV. Tweaker

Yet again, you assert yourself as a champion of mediocrity. It's nonsense to equate a tiny brass acorn nut from a hardware store vs. the enormous brass footers from Mapleshade. I experimented with brass acorn nuts years ago, and found the only function it provides at best is that of an inflexible tripod support, with no other benefit other than being a cheap tweak vs. typical stock plastic feet.
And yet again you distort or misinterpret what I have said. Please show me where I said that small brass cap nuts compared as equal to or better than Mapleshade's larger brass footers. 1 million dollar reward for that info. What I said is that they bettered the Black Diamond racing cones,IMO. I use much larger brass footers than 5/8 in. brass cap nuts. I put this suggestion forth as an easy, inexpensive first test to see what brass may or does sound like. Certainly Pierre believes his footers sound much better than the BDR Carbon fiber cones. Should be an easy cool million for ya Duster. It's in an escrow account so I don't spend it all on audiophile jewelry. Put up or? Tweaker EDIT: I'm wondering if being called a Troll should be considered an adequate answer to the above inquiry?

Yeah and I would guess Ayre and Cardas think there little Myrtle wood blocks are better than the brass cones.
Gee, it must be system dependent. I don't like the wood blocks, I do like brass cones under my speakers.
The BDR cones which I got used, sounded better to me than the isol-blocks.
Duster's sharing a seemingly new footer/isolation design and you jump in with your acorn nuts. You're kind of a one trick pony, but it is more like two tricks. We have the bigger gauge wire in all applications trick too.
I also like rubber stoppers from the hardware store, now that is a low cost footer.
I would like to try Duster's suggestion for me, as I think they might be ideal under my power amp. Preamp too, as it weighs like 30lbs. I didn't try the BDR cones under my amp, I only bought 8 of them. Every time I have tried something directly under my amp, I have gone back to the stoppers. Well actually my amp has a base of 1 inch veneered mdf[?] sitting on 1 inch brass cones, then a cutting board on isol-blocks, with the stoppers under the amp. I have carpet over concrete, no basement.
When it comes to footers/isolation devices, there is science, there is diy, there are myths, and there are personal preferences.
More false statements about me, this time from Jeff Star. Calls me a two trick pony. Being called a Troll by Duster I can take but a two trick pony gets my hackles up, whatever hackles are? Let's see is someone out there can count beyond two. Carbon conductive grease in the signal path, silver conductive grease in the power supply, putting brass, then wood then EAR Isodamp under equipment. Damping components with Mortite. Parts upgrades which include capacitors, resistors, larger current active devices in power supplies and SS amp outputs. Large cap. value across the AC line. Sanding cd edges, using purple and black paint markers on CD's, using Brillinize on CD's, using a demagnetizer on CD's, wiping cables with Brillinize. Well more than two, I think? Any other preschoolers out there?? I take on all preschoolers. It's my specialty here on AA.
Nothing to see here.
The subject line, that's sarcasm, but I not looking for a debate. Seems every time I encounter you, it is one of the two topics I mentioned. I'm still curious about your system, with all the tinkering, do find time to listen to it?
Yup
;-)
Hi Jeff,
I noticed you have Black Diamond Racing Cones placed under your preamplifier. I use modified BDR Cones under my preamplifier and power amplifier. It's a very easy task to DIY assemble:
The diameter of the particular 40mm x 10mm Carbon Fiber Disc I mentioned fits perfectly over the base of a BDR Cone. I glued a 40mm x 10mm Carbon Fiber Disc to the base of each BDR Cone with Liquid Nails silicone adhesive, then affixed a 40mm Herbie's Audio Lab Thin grungebuster Dot with adhesive backing to the bottom of each Carbon Fiber Disc. This created a 3-layer footer, with all layers serving a particular purpose in how the design functions as a vibration/resonance control device:
For the most part, Steve Herbilin of Herbie's Audo Lab's designs inspired the design. Steve's Iso-Cup design uses a coupling device positioned directly under the bottom of a metal component enclosure, then the coupler is affixed to a compliant but controlled bottom layer base that functions as an effective decoupler when placed upon a rack shelf surface or platform surface.
So, when the BDR Cone modified with Carbon Fiber Disc footer is positioned on a rack or above/under a platform surface, the cone side of the footer is placed "upside down", meaning the tip of the cone makes direct contact with the most *rigid* surface area available to couple with (the metal enclosure) rather than pointing down into a more soft/compliant material like a wooden rack shelf or platform. Then, the carbon fiber disc is adhered directly onto the flat side of the BDR Cone, which acts as an effective resonance dissipator and vibration wave blocker. Finally, a 40mm Herbies Audio Lab Thin grungebuster Dot, black version, with adhesive backing, is affixed to the bottom of the 40mm Carbon Fiber Disc to function as a good sounding and effective anti-skid pad for good horizontal sheering stability, and minimal decoupling between the footer and the surface it's placed upon.
I find it to be the best sounding footer for use under both my preamplifier and power amplifier.
It will go on the to do/wishlist.
I bought a couple of Herbies tube dampers when he was first starting out. I still use them on the bedroom preamp. Good stuff.
