Isolation footers for amps

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.

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.

Geez, you ask Robert what time it is and he tells you how to build the clock. Not to mention much of what he said (as if they were his ideas) I just said in my post yesterday. Can this possibly get any loonier? Note to self: That’s exactly what Michael Green would do, come back after feigning insult with some 3000 word retrospective of his life work. As if he suddenly has the right to bore everyone to death. As I intimated somewhere else we should maybe consider a firewall to keep the pro audio oriented folks from interacting with high end audio dudes.

Then don’t strike them with a drum stick. Problem solved.

Geoff, since taking a class in tile, I have been fascinated by the fact that ceramic tile, which of course is clay, can be hardened to the point that it has properties, versus all others, to with stand reentry heats and pressures on space equipment reentry.

Yes, thermal tiles (glass) on the Shuttle could withstand enormous temps circa 3000 F during reentry circa 17,500 mph. Assuming the tiles remain in place, of course, which actually wasn’t the case in the second Shuttle disaster when the vehicle disintegrated over California or wherever.

I am very familiar with both of those cones and have them in my system at various times, as well as a great many other cones. One difference between the DH Cones and the brass cones is the hardness; the NASA grade ceramics in DH Cones is almost as hard at 9 + as diamond 10 on the Mohs hardness scale and brass is much much softer at 3-4 on the hardness scale although you wouldn’t intuitively think brass would be that soft. As I intimated previously hardness is directly related to effectiveness. The shapes of both are ballistic which is a good thing, both somewhat resembling the nose of an ICBM. Effectiveness is probably due to several things, most particularly rapid transfer of energy and isolation. The NASA grade ceramic cone would also be stiffer, I.e., more resistant to bending forces (isolation) than brass.

Robert, I’ve had this same discussion with Michael Green a hundred times. No, more than a hundred times. We argued until we were both blue in the face. Night and day for at least two years over on Stereophile Forum. Don’t believe me? Go look, all the discussions are still there. So, you’ll have to trust me on this, you are channeling Michael Green. It’s the same situation, exactly. Let me be more specific. Obviously it’s possible to over-damp something or to use the wrong materials. Noone is recommending either. Anything can be done wrong, no one is recommending doing anything wrong. If you are not getting good results with damping you are doing something wrong. Michael used to repeat the mantra, speakers are musical instruments over and over as if repeating it over and over would somehow make it true.

Also, nobody has suggested it’s not a good idea to evacuate vibrations from components as rapidly as possibly. Certainly not me. I’ve always recommended a combination of vibration isolation and rapid evacuation of vibration from components. Have you been sleeping through the discussion of NASA grade ceramics? Why are you and Michael Green SO dead set against vibration isolation? Why are you both so stubborn? Is it the Backfire Effect? It just makes you both seem a little like Col. Kurtz in Apocalypse Now, operating without any connection to audiophiles or physics way up the river in Cambodia. One assumes the seismologist you hired or were going to hire, whatever, was unable to straighten you guys out and you fired her. Lol you saying it’s my way or the highway. I say it’s the Lost Highway.

You’re absolutely right, Robert. You can’t isolate anything 100%. Only about 99%. Let’s put it this way - perfect enough to be able to detect gravity waves, the amplitude of which are on the order of the diameter of an atomic particle. Hel-loo! And certainly perfect enough for such relatively mundane endeavors as electron microscopy and high end audio. [Note to self - Wow! It’s like he’s channeling Michael Green. Spooky.] Sigh, I fear it’s a little too late for the hystrionics as the Genie got out of the bottle a long time ago.

I would be remiss if I didn’t mention my new Super Stiff Springs are on the high end of the performance scale but on the low end of the price scale, coming in at a mere $12 per spring. Each 2" cryo’d spring can handle around 40 lb. Super Stiff Springs are just the ticket for heavy amps, heavy turntables, and subwoofers. Our Cryo Baby Prometheans can handle almost all other isolation projects, they are rated at 10 lb each. Now you can isolate everything for a song.

I’m giving serious consideration to yanking the magnetic suspension out of a 2017 Mustang GT350R and seeing what that baby will do. Yeah!

I suspect minimizing the area where seismic vibration can be transmitted to the component to tiny points AND using very stiff materials to resist bending forces) for the cones are good for isolation, especially when used in conjunction with "real isolation" devices like springs, as I mentioned in my last post. In addition, I’ve always maintained DH Cones or other cones should be used under components that are placed on isolation stands as well as under the isolation stand itself. So, it’s probably accurate to say cones are coupling devices AND isolation devices, no? They're TWO, two mints in one! Click! Click!

Timely tip: the thicker the slab is, whether maple or granite or bluestone, the stiffer it is, so the better it is in resisting bending forces. Building double structures can be quite interesting, too.

A big shoutout for Super DH Cones from Golden Sound, ballistic NASA grade ceramics, the next hardest material to diamond for superior energy transfer. For the most demanding systems. Exceptionally open and dynamic sounding.
