Equipment Rack


Does it make sense to spend several thousands of dollars on a equipment rack, if Stillpoints are used under every component?

Hey agear i play guitar ! now thats is annoying lol ( why do you need 20 plus guitars ?? That ones is all scratched up and old lol) ... Pick up a trumpet and start learning it in the living room your lady will love your system.. Lol 
Agear: "The take home message is simple: time for some new material. We are all here to be entertained (as well), and the last thing we want is for Grandpa to keep telling the same stories....;)

Would it be safe to assume (no pun intended) since you apparently have no sense of humor you’re not a proctologist?

I have a good sense of humor, and you provide plenty of unintended comic relief Geoff....

Oleschool, I have two small children (4 1/2 years and 19 months).  Hannah already has as guitar and Julia has access to cymbals, drums, etc.  You can see pics on one of my system threads......:)
excellent ,i have an 19mnth  Jan17th she loves music ,she will be a musician for sure ...


To the OP's post, Yes, it all depends upon your room /house construction. Whether or not your tt is floor/wall mounted.

Stillpoints are designed to specifically address micro vibrations. Especially with the Minis. These micro vibrations are of the sort that come from internal transformers and the like.
astro, why are the minis more adept at handling "micro vibrations" than the standard Stillpoint?

Bobby says "No comment on Mike Green."

Charley and I called Bobby (Robert) Mr. Grump.

You know sometimes you have to step away and see where people land. For myself, I'm a happy listener and always have been. This particular part of the music biz has more than its share of peculiar theories, myths, personalities and home brews. 

A lot of folks over the last several years have asked about me or made up their own versions. Well facts are facts, and the fact is RoomTune sold in 37 countries and here in the states had 650 dealers. We were used in more reviews than almost any high end audio specialty company between 90-97 in the industry. We also supplied more free product to the trade shows (and loved it) than anyone. Fact is when the mom & pop audio stores shut down it was something that shook the hobby forever. Many great companies went under and some of the rats started feeding off of the other rats.

Fact is I'm happy for Bobby. Even though he and I look at life through different glasses and disagree on some past blurred lines, he and his friends have built a pretty cool gig.

history

Robert was a dealer of mine before he started his current company and worked for me for a time. We shared in one idea and one product, a cone. The fact is, the Audiopoint was designed around 1990 by a guy (Brent) who was doing business as AMD (audio machine & design). I liked the sound of that cone and began marketing it. In reviews you will find it was called Michael Green's Audiopoints. Of course we wanted to correct this but I also wanted a different design as the cone at that time was still going through some growing pains sound wise. I think Bobby came on board with RoomTune in the mid to late 90's and when he left MGA/RoomTune took on Audiopoints for his own.

As far as the "rats" comment, people need to decide for themselves how things in a small industry, like this one, evolves from one idea to the next and how designs and designers move on to different adventures as well as the listeners who follow them. Maybe it's not rats as much as it is mice, not sure if they want to share their cheese or keep it to themselves.

The only way to find out is in the privacy of your own private concert hall called your listening room.

as my friend says "enjoy the music" 

I had to go do some listening for a client so the above post is part one, the MG-Bobby story. If your confused, maybe that’s a good thing cause the stories that have been brewed up about that time are pretty stupid. Bottom line is Bobby worked for me then wanted to do his own thing after his time with RoomTune came to an end. Hopefully that clears up the whole Audiopoint thing, as well as why Starsound might seem somewhat like the MGA story.

There are other audio companies that were born from the RoomTune MGA revolution who have their own stories as well, no biggie. It's a fact that most of the companies you see today are usually spin offs in some way or another. No harm in that. I enjoyed being one of the pioneers as well as being a part of other creative ventures.

part 2, another topic really but because my name was mentioned

Part two of my post is about Geoff Kait. Geoff has a Sony Walkman Cassette player with earbuds and spends his time trolling audio forums for the sake of getting nothing more than a rise out of folks. It’s entertaining if you are a little on the warped side, but as is often recommended best to just report geoff and let your mods take care of things.

For the record, I have never had discussions with geoff kait and was only a victim of his trolling on Stereophile. We could have had conversations if he was legitimate but many members pressed him only to come to the same conclusions. This forum will no doubt head down the same path if trolling is allowed. The Stereophile forum which once was alive is a graveyard now sadly do to trolling. nuff said 

Lastly

As I revisited this forum the last two days I see a lot of members asking questions that are not only down my alley, but I specialize in along with as I said earlier what happened to MG. Let me help by saying, if your interested in what I do or why, you should really come to our site and our forum and ask instead of going to other forums and becoming part of high end audio’s National Enquirer. The reason why this industry didn’t see me for a while was because of what I talked about before, the market crash. But the main reason was because I couldn’t stand the audio myth makers standing on every corner telling you your system sucks and why without ever knowing you or your sound. I got tired (bored really) seeing an industry with so much potential choosing to go down paths that had nothing to do with getting good sound. I wasn't alone!

Getting great sound isn’t really that hard and those who can’t get it always seem to get stuck in that revolving door of opinions. It’s a spin and a game that has caused many music lovers to pack their bags and leave. I know because many of them get ahold of us and start from scratch. Those folks your rarely going to see on yours or any other forum. They want nothing to do with the spins and are now happily focused on their music collections, great sound and life.

So why am I here? I’m simply stopping by to let people know MGA/RoomTune is still around and having a blast. I saw some of the stories about me and us on threads here and decided to give a shout out to those folks thinking about tuning and to invite others to come see what tuning is about. I’m not going to hang out but might stop by from time to time if it’s ok.

so that’s it

Have a great weekend and take advantage of this great hobby!

actually, one reason I was interested in a portable battery powered system was Mike Green’s insistence that low mass systems are inherently better than high mass systems. So, in reality my portable walkman with Ultralight headphones subscribes to Mike Green’s concept. Anyone not see the irony that he should attack my low mass system? Oh, maybe he means only HIS low mass systems...

If you like I’ll count the discussions we had together on Stereophile. Three years of them. Hel-loo! The main point of contention is that you eschew damping and vibration isolation, instead preferring to allow the vibrations to be free to move wherever they wish. Did I state your position correctly?

Somehow I’m thinking that people can read for themselves if they wish and come to their own conclusions. I’m not sure their conclusions though will be any different from the one being established here.

It seems to me that Robert’s invite to Geoff to visit with him would be the right way to show the differences or commonalities between Geoff’s thoughts and Robert’s.

also

If Geoff was sincere about tuning concepts he would be coming over to Michael Green’s TuneLand instead of coming to other forums pretending to represent what MG, or anyone else as far as that goes, is actually saying and more importantly doing.

The door is always open for those who wish to explore concepts and designs, but when forums reduce talks to dumbing down talk only, without the actual doing, the whole hobby is reduced to dumbing down.

As Robert invites Geoff to explore for himself so do we at Michael Green Audio. Talk is talk and walk is walk.

Like i said before the proofs in the pudding ... I am a fan of let it vibrate it has made a noticeable difference for the better i run all audiopoints top to bottom 

Yep, the industry sooner or later will turn to tuning vibrations rather than trying to kill them. When we take a look outside of the high end audio mainstream we see that tuning is the norm. For example musical instruments.

well, actually proof sometimes in not in the pudding. I’ve had Audiopoints myself, quite some time ago, as I was one of Mike Green’s first customers. While I like the effects of Audiopoints, real vibration isolation is better in every way. And actually, now that I think about it there are even other cones and pointed things that are better than Audiopoints, such as for example Golden Sound's NASA grade ceramic Super DH cones. Things have changed quite a bit since thirty years ago, I think it’s fair to say. Vibration Isolation and resonance control is one area that has changed considerably, you know, ever since the introduction of the Vibraplane - twenty years ago. Time flies when you’re having fun. Cough, cough. While you fellows have actually done, by dismissing vibration isolation, is obtain what we refer to as a local maximum.

I,m not a pro geoff ,all i know is they made a marked improvemnent in my setup (guitars ya i know my way around the 100 plus i have owned after 35 yrs ).I,m sure there are better or newer setups i cannot respond because i use the audiopoints.Regardless of anyones comments pro or con.I personnally used them first under my spkrs-tighter bass and better soundstage openess,
under my sub -massive change in performance.
Under my tt -i got better low end and a more open sound ,and also they look cool under it lol.
 they are now under every piece of gear i have including my rack and power supply .I am a fan personnally thats all i can say .No more no less ,they improved "MY" sound .
       and yes i remember the day tip toes came out also and the old sorbathene audioquest feet  i was there in the mix back then,I was a saleman in the 80-90s  There will always be something newer and better and also alot of hype surrounding it . thinking back i miss my vpi brick :)

Hi oleschool

Don't worry about Geoff, he hasn't owned an in-room stereo system going on 10 years now according to him. Kind of hard to be credible on audio topics when he doesn't even practice the hobby.

Pretty cool that you get to go from playing your guitars to playing your music collection. Many of my clients are musicians. In some of my stereo stores I would build a tunable listening room on one side and a recording studio on the other. Nothing like comparing apples to apples.

have fun

Hi oleschool

Just got done with my late night listening and saw your reply so thought I would give a shout before I called it a day. Went up to check out Paul's website. "The Journey Begins" is a great page! What an experience for you to be friends with Paul, especially with you being a player yourself. Life is good!

Love the Santa Rosa area and the music Vibe all over that place. Good memories!

Oleschool, just in case I wasn’t clear, I am not disputing your results with the Audiopoints. Actually, I haven’t heard anyone make comments con, as you suggest. I was using Audiopoints 25 years ago. Furthermore, unlike the claims of both Mike and Robert, you know, the claims how Audiopoints work, I.e., by removing micro vibration from the component, vibration produced by motors, transformers, CD transport mechanisms, I trust I’m not putting words in their mouths, strongly suggests that the vibration in the component IS A PROBLEM, no? I.e., that vibration degrades the sound. Thus, allowing vibrations to roam free in the system or the room is probably not a wise strategy. Therefore, in light of the evidence that vibration, micro and macro, is not something to just slough off or ignore, then, gentle readers, you must agree that any vibration, regardless of source is a problem, no? With the Audiopoints, the seismic type vibration is free to come up into the system and degrade the sound. I don’t think anyone is prepared to claim Audiopoints stifle seismic vibrations.

also, let me remind everyone that I have always proposed a combination of very hard cones under the component WITH vibration isolation. I actually propose cones under the component and under the vibration isolation device itself, since in my world it’s necessary to allow all vibrations to exit the iso system as rapidly as possible. And for Mikes info, Mike who is so fond of the expression "walk the walk," I am actually currently using a combination of vibration isolation and cones in my portable Walkman set up. Thus, I allow micro vibrations to EXIT the system rapidly AND disallow seismic vibrations getting up into the component. I am also not shy about using a smidgen of viscoelastic material just in case some micro vibrations have somehow escaped my elaborate trap. The only good vibration is a dead vibration. Hel-loo!

vibration isolation and resonance control

What the SNL heck trolling is Geoff talking about now LOL!

I believe geoff is confusing michael green audio with starsound. I can't speak for Starsound but I saw nothing above that resembles michael green audio.

At the same time michael green's tuneland (the techno-zone) is enjoying all the new visitors reading our pages. You guys are more than welcome to become a part of the tuning revolution (as TAS calls us).

Next up, the Michael Green self promotion extravaganza. Don't say I didn't warn you.

Mr. Kait,

I believe you should do more research on vibration specifically in the studies of sound applications and musical instruments. In every recording studio and concert venue where I engineered sound, anti-vibration designs provided a deader (not quieter) listening space which always fatigued me. The facilities with hard surfaces always presented a live dynamic outcome when mixing or listening and that ‘live vibrant energy’ kept me totally responsive through extremely long sessions.

Vibration is not an enemy when related to sound and musical reproduction; it is a ‘constant’, very similar to how the human ear works.

Vibration contains all the dynamics and harmonic structures listeners seek to hear. There are properties, a phenomenon, formed from vibration that build and layer on “all” vibrating surfaces. These heavier amplitudes of energy forms resonance and propagates on “all” smooth surfaces.

If you research Coulomb’s Law and applied it to the recording sciences and sound, it might lead to a greater understanding.

What do we seek as listeners - live dynamics or dead harmonics?

You stated: And actually, now that I think about it there are even other cones and pointed things that are better than Audiopoints, such as for example Golden Sound's NASA grade ceramic Super DH cones. Things have changed quite a bit since thirty years ago; I think it’s fair to say.

Your background and education is in aerospace so we are certain some bias exists in that statement but just to be fair, you're listening assessment of Audio Points™ is meaningless when comparing products that cost tens ($$) of dollars to others costing in the hundreds of dollars ($$$). We are much more in favor of comparing devices of the same financial investment values. Our cost comparison product at this level would be a fourteen pound mechanical grounding plane we call the Sistrum Apprentice Platform™. We are extremely confident should you ever wish to compare ours to theirs. The differences in performance are measurable, highly audible and will sound much livelier.  

Agreed, a lot has changed in the past thirty years. The Audio Point still remains an Industry benchmark for very affordable vibration management yet has evolved into a much higher standard of performance when applying greater mass, geometry and physics hence the family of Sistrum Platforms.

You stated: While you fellows have actually done, by dismissing vibration isolation, is obtain what we refer to as a local maximum.

Not sure who you are referring to as “we” in your statement. Is it you and who else? I am sure the majority of listeners and readership does not understand the term “local maximum” so here is a brief definition provided by Wikipedia:

‘In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function, known collectively asextrema (the plural of extremum), are the largest and smallest value of the function, either within a given range (the local or relative extrema) or on the entire domain of a function’...

Please make your point more clear as to what it is we have actually done or accomplished?

In closing: One of our engineers examined your ‘Isolation Springs’ and noted there is a “shear component” as well as a “compression component” with a single metal conduit providing a “primary mechanical grounding conductor” which is very similar to our technical approach. Are you absolutely sure you products are actually isolating and not transferring resonance?

Once again, our understanding of resonance management does “NOT” dismiss the theories behind “vibration isolation”. We just disagree on the philosophy and principles behind isolating (storing) resonant energy within the component, loudspeaker or musical instrument without a mechanical means providing an exit pathway for the heavier amplitudes of detrimental resonance. Our ears do not listen to electron microscopes.

Strange he should ask since just about everyone and his brother knows that mass on spring isolation devices work by attenuating the transmission of seismic vibrations according to a simple mathematical formula. Obviously the isolation effectiveness is a function of the resonant frequency of the iso system and technique in setting up the iso device as I’ve already alluded to. Thus, even advanced iso devices allow some vibration up into the component. Duh! Nobody ever claimed these iso devices are perfect, or that there is perfect isolation. However, by minimizing resonant frequency of the device, maximizing the degrees of freedom one can obtain very good results. Spring based systems are well documented and are a proven technology for vibration isolation. One need look no further than the LIGO project to detect gravity waves to see just how well (talk about understatement) springs do in real science experiments. And by employing tricks of the trade, you know, tricks like cryogenically treating the springs, one can do very well. That’s why my spring based systems have been and are in some of best systems extant. In closing let me turn your opening snarky comment around and ask you, don’t you think you and your engineer could use a little research into vibration isolation?

tom, I think the boat has sailed already as far as my trying to explain vibration isolation. I have already explained myself numerous times. Prior to asking repeatedly to explain myself it seems only fair for you and anyone else who’s not caught up on the while vibration isolation thing, which was introduced to audiophiles twenty years ago, to at least look into what it is and specifically what seismic type vibrations I’m referring to and how specifically mass-on-spring systems perform to mitigate the sesmic type vibrations I’m referring to, I.e., the ones that make the entire building shake, not only up and down but side to side and in the three rotational directions as well.

I can certainly recommend Shannon Dickson’s milestone article in Stereophile magazine twenty years ago, Bad Vibes, in which he provides an excellent overview of vibration isolation and describes the operation of the then new iso stand, the Vibraplane.

Geoff,

When a thunderstorm rocks and rolls thru the limestone creek bed outback I can't hear that noise thru my cello's body laying on the concrete floor. Nor when the train a mile away can be heard late at night and under some different atmosphere that has the same non effect. I have tried. What may be good science for living on a fault line or under the elevated sure faults up speaker and audio components when listening to music.

You and some others have built a better mouse trap, one that does not allow for an efficient method for the wave forms that are self generated within any electronic component or speaker to leave the chassis. You have become highly accomplished at isolating this self generated component noise within a metal container or wooden box so it can be left to contaminate the signal that is to follow. Self perpetuating noise pollution for sure. What you won't let in, won't let anything out either.

I can’t tell whether you’re slow or just pretending to be slow. I’ve already stated on more than three occasions on this thread and elsewhere on these fora that both vibration isolation AND some way of dissipating vibrations generated by motors, transformers, acoustic waves in the room hitting the component, etc. I never said vibration isolation solves all vibration problems. I have always included a means for internal vibration to exit the isolation system, including the component itself. As I've said repeatedly. Follow?

Diversionary answer.  LIGO is irrelevant.  How about a cheap bedspring for a violin endpin?  Now that would make the music come to life.  

Since no one in the Audiogon ecosystem appears to be using your products, how about a pic of your own system unless of course its a lonely walkman as Monsieur Greene insinuated.   


agear - you observe

Since no one in the Audiogon ecosystem appears to be using your products
Fact is Geoff is not the only proponent of spring based isolation from subsonic vibration and I along with many well regarded reviewers and experts are getting great results from the current Townshend kit. Your attempts to dismiss his emphasis on the need to deal with the vibrations impinging on our systems as well as those generated within them are unhelpful. Remember this entire debate was triggered by a manufacturers assertion that his carefully shaped spike would reject seismic interference, an assertion he has been unable to provide any evidence for

There are waveforms and portions of waveforms that your methods do not account for but they do alter. Your methods directly eliminate portions of these waveforms that are crucial to how a speaker diaphragm works, operates and makes sound. It is all text book, you just haven't compiled the data. I thought you were much faster. Tom

Geoffkait: LIGO this the most sensitive physics experiment in history! the gravity waves which it detected finally last year had amplitude the diameter of a neutron.

To which agear responded,

"And the relevance of that in regards to audio is what? We are not measuring things but propagating energy. Again, a spring for a violin endpin? I think not. What have you actually measured in regards to your products and their performance or is it all quantum divination?"

the relevance to audio is that seismic vibration must be addressed in order to eliminate or attenuate external low frequency vibration where electrical and or optical components are involved, as they are in both LIGO and audio systems. For CD the nano nature of the data requires the laser beam to be relatively unaffected by low frequency vibration for optimum performance. One need look no further than turntable platters and tonearms and cartidges appreciate that low frequency seismic type vibration can excite the resonant frequencies of those items, resonant frequencies are circa 10 to 14 Hz, well below the frequencies of any vibration produced by the component or by acoustic waves. Follow?

I never suggested a spring for a violin endpin. Try to keep up with the discussion. It is very easy to calculate the effectiveness of isolation devices and you can find the resonant frequency manually for spring based devices. The effectiveness of a particular device depends on how well set up the device is, as I have already pointed out optimum performance depends on how the component is interfaced to the top plate and how the device itself is supported on the floor or table. Why audio magazines never measure the performance of iso devices is a good question as it’s not rocket science. There is no requirement for me personally to measure anything.

YOUTUBE Townshend audio How to isolate speakers from ground borne vibrations.

while it is probably true that the Townshend isolation devices prevent structural ground borne vibrations from getting up into the speakers wouldn’t the more important function of the Townshend iso devices be to prevent the speaker vibrations from getting down to the floor thus possibly producing what we generally refer to as acoustic breakthrough? Besides the speakers are going to be vibrating whilst playing anyway, so there’s not much the Townshend iso devices can do to alleviate that speaker vibration and it’s affect on the internal crossover, speaker input connectors, wiring, etc. inside the speakers, no?

Excerpt from Townshend website:

"Seismic Isolation Podium

Designed as a range to accommodate any size and weight of speaker – standmount plus stand, floorstander or subwoofer – the Seismic Podium breaks the acoustic connection between the floor and the speaker, preventing the passage of deleterious vibrations both to and from the speaker cabinets. For a detailed explanation of why this is an absolute necessity before any speaker can perform to its true potential, read ‘Earthquakes on hi-fi’."
