Isolation footers for amps

I was a machinist before getting into management about 30 years ago. That said I am fortunate enough to have some precision metal cutting equipment in my basement & the ability to use it. I made aluminum "tip-toes" about 25 years ago & used them exclusively under all my equipment up until about a year ago when I tried the DH cones. That was certainly an improvement which led me to try some other things. In the last 6 months I've made a few dozen different footers of various materials. All of them use bearings. I've found in my limited experience that various different materials in the same footer yields the best results. As Robert (who has a lot more experience than I) states above, everything makes a difference. I find that fascinating & am not done with my quest yet. Bottom line is footers can transform a quality high end system. That was something I wasn't convinced of until I started listening to different configurations.

At least I make an attempt to educate where you always working to disintegrate. I just read your bio??? huh?

>>>>I educate those who are educable. Never seen a real bio before? Why am I not surprised?

They are our ideas. Ours as in we, us, a company, specialists, people as in more than one mind. I imagine you are used to much different working conditions (pretty lonely at the top isn’t it?).

>>>>>>Specialists? So, you guys specialize in snarkiness? You guys are uneducable as far as I can tell. Like Michael Green. You’re just like him. It’s uncanny.

HaHaHa - pro audio interaction? Your not worth their time (hourly studio rates apply).

But enough of this horse trading.

SO:

Exactly what are NASA grade ceramics?

>>>>Uh, I’ve already explained it twice. If you were not so focused on promoting yourself and your "specialists" you would have already seen it. NASA grade means the ceramic material is much harder than standard grade ceramics. "NASA grade ceramics" are 9.5 on the Mohs hardness scale where diamond the hardest material is 10. Brass is way down the scale which helps explain why it doesn’t sound so good.

Is there a NASA grade of anything else other than a posted NASA Paygrade Grade Scale?

>>>>>>>This is an example why it’s so hard to educate some people.

I believe NASA® is a Registered Trademark. Since you represent a business and are promoting or advertising their good name, attaching it to another specific company and product repeatedly and often throughout this forum; do you have legal permission to use said Trademark?

>>>>>>Now you’re just grasping at straws. That’s just plain silly. It’s not even my terminology, it’s Golden Sound’s. Go sue them. I worked at NASA. By contrast you think NASA is a trademark? That’s too funny!

I just was informed you live only 4.4 miles (a five minute ride) from the gents who manufacture those NASA devices. How in the world do they put up with you?

>>>>Allen at Golden Sound moved to China 8 years ago? Wake up and smell the coffee!

Over and Out!

>>>>I wish. Good luck in your quest for mediocrity.

@geoff  - One last time...

I educate those who are educable.

That is your problem Geoff and not mine. In my opinion everyone who owns a music system especially those connected to an audio forum are highly capable of learning.

By contrast you think NASA is a trademark? That’s too funny!

It’s not even my terminology, it’s Golden Sound’s. Go sue them.

GS makes NO, None, ZERO mentions or displays of  “NASA Grade” ceramics - anywhere on their website. It appears you invented the term and are the proud owner of “NASA Grade”.

We got tired of always reading your continuous marketing on how superior NASA Grade cones are. You push the same opinion over and over again, just like stating you are going to save everybody time and money because of material hardness which is located on another thread.

Same old, same old… why not audition a platform? I will send you one for evaluation. They cost the same as the Super cones. Hear what a ceramic cone sounds like in comparison to a 12 pound six pointed 'vibrating' mechanical grounding device. It will at least give you something new to write about.

I mention Trademark and you say sue? You are not too street savvy if you actually believe we would spend time and money on a meaningless result.  

Specialists? So, you guys specialize in snarkiness? You guys are uneducable as far as I can tell. Like Michael Green. You’re just like him. It’s uncanny.

Funny Stuff  ⌣

I am the only snark in our company and only retaliate when fired upon.

You always track us on AudioGon, attempt to limit our participation through insulting our technology, our people and our intelligence simply because you do not have a clue or refuse to believe there is something new on the horizon - Why?

You always attempt to convince the readership that I am just like that Green monkey on your back. That tactic is definitely proving to be a lost cause. He is your buddy - not mine.

You remind me of the guy that purchases a seat in row 130 located at the very top of the venue, last row, end  corner seat as far away for the stage as possible; knows all the lyrics to the song “Wipe-Out”, screams “turn it up I can’t hear the vocals” at every interlude then bitches to the concert goers seated around you that the sound and sound man always sucks.

You are indeed a “Grandstander”!

I apologize to the readership and will do my best not to get trapped into a stupid verbiage exchange and ruin yet another thread. I will take geoff’s best shots and ignore them should there be a next time. Sorry again for taking up your time.

If you wish to learn more about vibration management from a new and different perspective, please telephone us anytime. We will be happy to chat.

Robert - Star Sound

Another perfect example of feigned feelings of insult with the standard self promotion blurb from Robert. Just like Michael Green. One assumes Robert learned everything he knows about vibration management from Mr. Green, too. He obviously learned how to insert his never ending long self promotion monologues from him. You’re like peas and carrots.

OP - check the flexy tube surrounds - if old ARC will sell you new ones

You could also buy some large ball bearings from a co. formerly called Small Parts Inc. - now part of, and on Amazon's website

then you can make or buy some concave 'cups' to put the ball bearings in

that is the cheapest way I know of to experiment with these things
