Do equipment stands have an impact on electronics?
agear, while that’s somewhat humorous (even though you’ve used that stale joke previously) what’s much funnier is that neither you nor the brain trust at Star Sound seem to know what shear waves are. Just more posturing and name dropping. i hate to judge too harshly but it certainly appears that at UVa the college places more weight on puerile humor than science. have a nice day |
It is my understanding that polarities of shear are best swept under the carpet where they can’t interfere. 😛As I said earlier (and monsieur Kait may not have opened up the link), the answer lies in isolating the listener with these bad boys. All you need is missing is a Machina Dynamica logo: http://www.zcoil.com/product/freedom-classic-graynavy/?gclid=Cj0KEQiA6_TBBRDInaPjhcelt5oBEiQApPeTF9Mo1bY-WbYvoSisDXfsODiu43nzIDMqRtIfQO1qoXYaAszZ8P8HAQ |
dlcockrum geoffkait: "Whew! Did I miss anybody?" Hi Geoff, Symposium Acoustics Svelte shelves and Rollerblocks (which do, I understand, "dissipate a polarity of shear that generates interfering energy") and edenSound TerraStone roller footers. I am enjoying great success with these products as of late. thanks for the info, Dave. It is my understanding that polarities of shear are best swept under the carpet where they can't interfere. 😛 |
and none of them dissipate a polarity of shear that generates interfering energy. In fact most of them unknowingly aid in the creation of more interference. More interference is a byproduct of many so called isolation systems including all those that are suspended. Careful what you wish for and video aides on the web can be both hazardous

There are what, twenty or so vibration isolation stands, platforms, spring systems, mag lev for audiophiles? All the Townshend stands and footers over the years, Stillpoints, Bright Star sandbox and air spring tables, Relaxa mag lev, Solid Tech, Minus K, Vibraplane, Vibrapods, cryo’d high carbon steel springs, Ginkgo, Bio Mikro G iso stand, Nimbus Sub-Hertz Platform, Silent Running, Daruma and other roller bearing systems, not to mention turntables with integrated seismic isolation systems built in like Rockport and Basis and others. Whew! Did I miss anybody? Not to mention all the commercial products audiophiles sometimes purchase for home audio, Newport, TMC, Halcyonics, etc. And let’s not forget DIY isolation devices like bicycle inner tubes, racket ball stands, Bungee cord suspensions, fishing line suspensions. Add up all the vibration isolation devices that have been sold to advanced audiophiles and what have you got, 100,000 vibration isolation systems? Something is happening but you don’t know what it is, do you Mr. Jones? 😃 |
Of course vibration can have an impact on turntable lathes and tables themselves. However, I’m not so sure about other components without moving parts being helped much by spikes and fancy racks, and that doubt has saved me some bucks over the years… Wolf, that is the gist of the thread and the standard bias many audiophiles have. We all know that vibrational control is effective with things that move (subs, speakers, TT, etc) but electronics is a more murky area for many. I have heard differences under computer servers as has cdrc. The question of the day was why and is there any data? So far there appears to be none. |
Of course vibration can have an impact on turntable lathes and tables themselves. However, I’m not so sure about other components without moving parts being helped much by spikes and fancy racks, and that doubt has saved me some bucks over the years…also I think the spikes I use under my preamp are Tip Toes (they’re well made heavy buggers) I bought a LONG time ago, along with some extreme sorbothane feet under my tube amp placed there to allow more air under it and so it doesn’t move when I hit the start button. |
Are suggesting that things that we knew nearly 70 years ago ago is no longer knowledge? Or are you just not aware that the history of stands and things like anti-vibration platforms and Tip-Toe-style points have been around a whole lot longer than you thought?? Clearly the effects are measurable (and audible too) and its not rocket science as you’ve been suggesting.Not at all but merely asking for data points relevant to the thread (in other words a measured change in an electrical parameter after correction for vibration....). I am aware of the history to a limited degree but the usage of vibration products is a more recent focus of our energies. Most people still think its a waste of time when it comes to electronics. I am not one of those.... |
Believe it or not, isolation is like everything else - system dependant! Almost two years ago I received a Baetis Reference music server with custom Sillpoint footers and the Stillpoints did absolutely nothing to improve the server's sound. So, I removed the Stillpoint footers and placed the Baetis unit on a Star Sound Technologies Apprentice isolation platform and the unit came to life, in fact, it sounded like a totally different unit and this is no lie. Needless to day, I sold the Stillpoints. The bottom line is like everything else...you have to try what you are considering to determine if the investment is worth the return. BEFORE you invest in isolation be sure to 1) completely have your component settled/burned in and 2) make sure you anally voice your speakers to your room. Proper setting up and voicing your speakers to you room is something many people overlook drastically robbing them of the performance. Spend the time to voice your speakers to your room (and not the other way around as so many people do). When you achieve this, you will hear stuff in your music that you never heard before. At this point you can consider isolation properties. Some great pics of Star Sound Technologies isolation products appear on my Auduogon virtual system here:Beautiful system and part of the world you live in and VERY sage advice regarding speaker setup. That is no joke and much trickier than philes understand. |
I am still waiting to hear from you or anyone else a corollary in audio. Furthermore, even if you could lock into a given finding, would blinded audio nerds or lay people know the difference?I’m sure I’ve mentioned this before in this thread, if not, I’ve mentioned it elsewhere so here it is again: We own a Scully LP mastering lathe equipped with a Westerex 3D cutter head. You can see it on our facebook page. The lathe sits on a special anti-vibration platform via a set of adjustable stainless steel points. The platform in turn sits on a custom table built for the lathe that also has adjustable points going into the floor. Now the lathe, platform and table were built about 1948 (the cutter head about 1959). Clearly they understood the issues of vibration affecting performance that long ago.

I’m utterly unconcerned with seismic vibration, although I do have vibrapods under things and a set of groovy cones (had those for many years…they look GREAT) under my preamp to add ventilation and because they look cool. All costing me very little money. Maybe I’ve addressed this issue accidentally in my home rig, but in live concert situations using 1000 watt amps and subs, I simply don’t see that any isolation potential exists. My main beef is with claims of substantial and audible improvements from uber expensive racks and $500 metal feet. Silliness in my view, and Barry Diament seems as delusional as geoffkait, although that might be a stretch. Note that I use guitar amps that have the speakers in the box with the amp…seismic indeed.Seismic is good unless you are performing SEM and need absolute stillness and then maybe springs make sense or something along these lines: http://www.kuzma.si/zerovibe-6050p.html . Speaking of 1000 watts and subs: https://www.youtube.com/watch?v=K5hBXr3aJus Robert from SS comes from a Pro Audio background.... |
You are right and I am wrong; however, understand I use isolation in the loosest sense for all Audiogon community backgrounds. The correct term that Star Sound uses on its platforms are "Energy transfer systems". Is Star Sound into sales or consulting?? With that in mind, you get the gist I believe about savvy name engineering. Thanks for bringing this to our attention though!!! The important thing Agear is what you try may not work for me or Geof. You really have to try the product in your system and in your own sound room for a few weeks minimum and that is all that is important no matter what you want to call your approach to vibration control. I told my son that Star Sound Technology platforms are just great big peanut butter and jelly sandwiches and he gets it.More importantly, if your wife and kids can hear a difference in your system with and without springs then you are onto something. |
Just cut to the chase and listen to a Sony walkman like Mr. Vibrations and all these problems solved except for Walkman vibrations of course. The human hand coupled with the footwear below provides the penultimate isolation for audio purposes: http://www.zcoil.com/product/freedom-classic-graynavy/?gclid=Cj0KEQiA6_TBBRDInaPjhcelt5oBEiQApPeTF9Mo1bY-WbYvoSisDXfsODiu43nzIDMqRtIfQO1qoXYaAszZ8P8HAQ |

wolf_garcia Half of geoffkait’s posts are re-posts of whatever he’s responding to, which I feel is a waste of pixels as what he’s responding to is already there. That said, I also feel that there’s a lot of money spent needlessly on various spiked or isolating or otherwise insanely over designed audio shelving, speaker cord holders, expensive cones, spongy decouplers (I use those…not sure if they do anything except under my speakers), and other stuff that does nothing audible. Note: Vibration touches everything anyway if its in the room with speakers, and that’s OK…really…it is... Hey Wolfie, let me get this straight. You’re an audio engineer, right? and you don’t see a problem with vibrations running amok in the room? That’s weird. Barry Diament, you know, the guy who remastered the Led Zeppelin Catalog, is the complete opposite. Here’s the intro to his article on vibration isolation, note LINK to full article follows intro. INTRO TO BARRY DIAMENT VIBRATION ISOLATION "What I’ve found is that all of our components are being substantially inhibited from delivering their best because they are subject to external vibrations. By far, the most sonically and visually degrading are those vibrations in the ground that enter the component via its feet. These seismic vibrations (the ones very low in frequency and amplitude, so tiny we don’t even normally feel them) are creating spurious signals within the sensitive circuitry of your components. These spurious signals mix with the real music and video signals to distort them, hardening the treble, thinning the bass, muddying the soundstage and annihilating dynamics. Seismic vibrations add grain to video pictures, ruin color purity and contrast and soften focus. I’m still having a bit of trouble accepting that the ocean tide or the wind or a truck changing gears 1/4 mile away has such a profound effect on the performance of my audio and video gear. What I have no trouble with is the results of isolating my gear from these effects. The performance gains in every parameter I can think of are clear, consistent and repeatable. Frequency extension into the treble and downward in the bass is improved. Stereo imaging gets better focused. The soundstage takes on greater proportions. Dynamic swings both large and small are more like real life. Overall, there is a much greater sense of the system getting out of the way, leaving the listener with a considerably increased sense of contact with the recorded event. The color, contrast, focus and purity of video signals is improved. None of these changes can be described as subtle, as they are very easy to perceive by all listeners and viewers. Best of all, the differences between sources (different recordings and different movies) are more easily discerned. This is important because recordings and movies vary in quality and the ability to perceive qualitative differences speaks of the resolving capabilities of the playback system. Seismic isolation. Those two words are the key to knowing what your components can and cannot do. The benefits extend to loudspeakers as well. In fact I have yet to find a component that doesn’t significantly benefit from seismic isolation. Some, like source components (for example CD and DVD players) and loudspeakers show the largest improvements but even power strips benefit from seismic isolation. After all, they too contain electrical signals which are subject to degradation by seismic interference." See Barry Diament’s page on vibration isolation here: http://www.barrydiamentaudio.com/vibration.htm Have a nice day geoff kait machina dynamica advanced audio concepts |
Rather than waiting for measured "proof" that any given product marketed as providing isolation from vibration actually does so (and further, that such isolation is not just academic, but actually provides an improvement in sound), you may in many cases try one and decide for yourself. Symposium Acoustics, makers of a couple of different roller bearing feet (named Roller Blocks) and isolation shelves, sell their products with a money-back guarantee. If you don't hear a difference, or one too small to justify the cost, return the product for a refund. Unless you aren't secure in your own ability to hear, and need an authority figure to validate your purchase decision ;-). |

erik_squires wrote Remember that in audio, the FTC sets some standards, but doesn’t measure the gear. It’s up to the equipment makers to measure and make claims, and occasionally magazines test them to see how close they are to the specifications. >>>>>Really? The FTC sets standards for home audio? Id be curious to see any more info. as i already stated, manufacturers are under no obligation to either measure anything or make any claims. They can if they wish. there are some things in this hobby that are simply not amenable to measurement. See if you can name 3. >>>There are no measurement requirements or protocols for home audio. Obviously there are certain standards involved such as Redbook CD and DVD and Blu Ray. There are no standards for noise, distortion or even Dynamic Range of home systems. Standards and protocols are not legally binding AFAIK\, CDs are produced that are not Redbook for example. Where are you coming up with this stuff? Have a nice day |
erik_squires @geoffkait "Then please tell me a model to mathematically describe the effects of microphonics and vibration. Lacking that, it IS trial and error and devoid of engineering." Ironically, we don’t have to model microphonics or vibration. We model the damping method or isolation method. Thus whatever vibration one has to do with we will know the effectiveness of the solution. For isolation devices for example we know that the ISOLATION EFFECTIVENESS - for whatever the local vibration environment looks like - is a relatively simple calculation based on spring rate, load and resonant frequency. So, obviously one would want to design his iso device with the lowest possible resonant frequency. Then the isolation effectiveness for any given frequency of vibration will be the highest. As I’ve said repeatedly no model can describe all vibration situations since there are wide variations in local seismic vibration (traffic, etc.), audio system characteristics - e.g., transformer noise, motor noise, speaker SPL, etc. Erik again, "Weren’t you a few pages back arguing it was impossible to use basic engineering practices to stands? Perhaps it was another camp." No, it was not me. It must have been someone else. Since I am an engineer and a theoretical physicist I tend to use engineering practices and correct physical engineering theory. Erik again, "Or we are stuck at trepination and therefore unable to develop even aspirin and ibuprofin for headache relief." No we are not stuck at trepination although this thread is starting to give ME a headache. Erik again, "I’m sure there are makers who can test their stands and make them vibrate less. What’s lacking is an explanation and model for what of these characteristics makes an audio system sound better. That’s what I mean about the loop not being closed. You can take a course in loudspeaker driver design, where you would dissect and analyze everything from an AMT to a fan-based woofer and know how to put those numbers together to explain the subjective effects of your choices in materials, magnets and coil geometry. We have no such thing for vibration control in audio. Usually around here some one responds "But we don’t need engineering...." and we go all the way back to making holes in customer’s heads for pain relief." No need for all the drama. Vibration control and vibration isolation is a VERY mature science. Not need for hystryonics. Here is a quick study page for vibration isolation from Kinetic Systems. Save the drama for yo mama. http://www.kineticsystems.com/page306.html Erik again, "They could sell a bazillion "vibration isolators" and it’s no proof to me of anything besides good marketing. Imagine even a light bulb being made today without a thorough understanding and accessibility of the sciences involved. Power, current, efficiency, materials and emitted light spectrum. Forget a light bulb, a chef’s knife has more science behind it than vibration control in audio." There are many vibration control and vibration isolation devices for audiophiles. Your job is to study up on what vibration control and vibration isolation is all about so you are knowledgeable enough to make an informed decision regarding such devices, the cost of which range all over the place. As I keep saying the most technically challenging scientific project, or at least one of them, LIGO, was forced to employ vibration isolation in order to reduce the instrument’s sesitivity enough to observe gravity waves. This is not really a case of trial and error. It’s a case of understanding the underlying physics and requirements. Although now that you mention it, TRIAL AND ERROR is actually part of the scientific method and can be quite useful. Nothing wrong with them apples. In fact a lot of things in this hobby are unpredictable Inasmuch as how they will work out in a given system, no? geoff kait machina dynamica give me a strong enough spring and I’ll isolate the world |
