Agear -- are you bent on simply ignoring all evidence to the contrary and pimping SS above all else? As I and many others have observed and attested to these effects are far from theoretical, they are real and the impact of addressing them (via suspended or spring solutions) is real and profoundHuh? As Townshend points out on his web site, and as I’ve pointed out as well, isolating the speakers has two advantages:All theoretical advantages only. Again, the raison d'etre of this thread.
(1) it prevents low frequency vibration from getting up into the speakers and affecting wiring and electronics, RCA connectors, etc. and (2) it prevents speaker cabinet vibrations from feeding back via the floor to system cabling on the floor, electronics, turntable, CD player, what have you. That’s also, by no coincidence, what my springs do for medium-size speakers and Subwoofers.
Do equipment stands have an impact on electronics?
Mechanical grounding or isolation from vibration has been a hot topic as of late. Many know from experience that footers, stands and other vibration technologies impact things that vibrate a lot like speakers, subs or even listening rooms (my recent experience with an "Energy room"). The question is does it have merit when it comes to electronics and if so why? Are there plausible explanations for their effect on electronics or suggested measurement paradigms to document such an effect?

agear OP: "decouple the speakers from the room which I guess can be an advantage depending on room nodes, etc" Geoffkait:Depending on room nodes? Huh? What on Earth are you referring to? to which Agear replied, "Not anything to worry about with your Walkman...." That’s what I thought. You don’t even know what isolation is. Let the insults fly! |

It’s not only theoretical, silly. Vibration isolation is a very well established science. Even for advanced audiophiles it’s been well established for at least 20 years. Now that I think about it, by inference that would make anyone who doesn’t use isolation as not advanced. As I’ve oft pointed out on this forum one need look no further than LIGO for the absolute proof that the seismic vibration problem is solved by vibration isolation, that vibration isolation is not some theoretical machination. LIGO could not have succeeded without vibration isolation. Scanning electron microscopes won’t even work without vibration isolation. Geez, you’d have to be living in a cave to believe isolation is only theoretical. But I can certainly understand why you make these ridiculous arguments and "scathing insults" having dealt with the Tuning Meister himself every day for more than two years. I totally get where you guys are coming from. As I intimated the other day all of this confusion on the part of you guys could have been prevented if you had been paying more attention all this time to what others were doing and what progress was being made and avoided the pitfalls of stove piping vibration solutions. |

There is no evidence for any of this stuff and thus the point of the thread. There are apparently "engineers" involved with some of these products but no data whatsoever, just pseudoscientific intuitive and fights of fancy (and youtube videos). You heard a "change" in your speakers. Why? Spectral analysis would be easy to do with and without stands (for an actual engineer....maybe not a NASA custodian). In audiophilia, an audible change is often the end game. Philes experience a change and that keeps them going without knowing what changed and why. |

There are apparently "engineers" involved with some of these products but no data whatsoever, just pseudoscientific intuitive and fights of fancy (and youtube videos) You are obviously not trying very hard to unearth this evidence? Here are several examples using your preferred method (accelerometers) supporting two of the items I use in my system 1) Shunyata Dark Field Elevators for cable isolation http://www.shunyata.com/images/technical_features/dfss-chart.jpg 2) Grand Prix Audio racking systems -- which include a variety of isolation methods including ball/cup feet exactly to deal with floor borne vibration (Apex footers) http://www.grandprixaudio.com/research http://www.grandprixaudio.com/products/apex#product-features And for a more insidious problem here is a technical discussion of vibration induced jitter in CD playback http://www.industrial-electronics.com/DAQ/optical_discs_digital_data_and_vibrational_jitter_effects.html None of this is mumbo jumbo, it’s all established science -- two minutes of online research turns all of this up -- personally I thought this thread had morphed into more of a discussion of how to address these issues rather then whether they were worth addressing |
