Some companies specialize in audio equipment 'isolation' equipment - and these can cost hundreds or thousands of dollars. From the reviews I can gather from these - much like speaker cables - the reviews always seem to gush about how much it improves the sound and the more expensive it is - the more they gush about it. But I can't tell if these reviewers are actually being sincere or not. I haven't tried these components nor measured their effect on sound quality but I am curious how much of it is truth and how much is BS. For example:

Townshend Audio Seismic Platform ($2600/pair)
From Absolute Sound:
For solo piano there was greater clarity between note fundamentals and trailing soundboard resonances. I noted this same clarity time and again with soloists in general, from violin, guitar, winds, and brass. The overall effect was a refinement and focus akin to achieving just the right amount of speaker toe-in, or precisely dialing in a cartridge.

Bass response, extension, and pitch definition were clarified and delivered in natural lockstep with the rest of the frequency spectrum. Low-frequency weight was evenly balanced and reflective of the musical source material. During Cat Stevens’ “Hard Headed Woman” from Tea For The Tillerman, the kickdrum sound (which is particularly prominent during the song’s bridge) was more tactile and complex, with a greater sense of the drum skin moving air back and forth under high pressure.

The other major takeaways regarded loudspeaker localization and soundstage dimensionality. As for the former, the loudspeaker simply vanished. It just couldn’t be localized as a source anymore. With the Podium in place the orchestral soundstage became infused with sharper contrasts and richer colors. The Podium delivered greater intensity and timbral detail, improved dimensionality, and clearer placement of images. I also noted during Ray Brown’s “Teach Me Tonight” [Soular Energy] that vertical information was enhanced—the cymbals on this track were lifted higher, and sustained longer seemingly on a raft of air.

Of equal importance, the Podiums preserved the general tonality and balance of the loudspeaker. Whether your current system’s overall voice is dark and ruminative or light and airy, these characteristics remain untouched. The Podiums don’t insinuate themselves over the music; they are essentially characterless. The difference is that any suggestion of confusion, confinement, or congestion is ameliorated.

The pleasures of the Seismic Podiums can sneak up on you at the oddest moments. For example two of the most commonly played male vocal tracks I listen to are Tom Waits’ “Georgia Lee” and “Take It With Me” from Mule Variations. Waits’ raspy voice is rich with deep chest tones, perhaps at times overly resonant. But with the Seismic Podiums there was a small but critical shift in this perception. Earlier hints of resolution-loss and smearing during his vocals seemed to vanish as if a light fog had drifted away—his voice rising to the surface of the mix with greater timbral detail and clarity.

It’s axiomatic that in high-end audio everything makes a difference. But sometimes the line between observed “difference” and genuine improvement is tough to judge. There is no doubt where the Seismic Isolation Podiums stand on this point. They lifted my loudspeakers and overall system to a much higher and more musical level.

The Podiums are not inexpensive, but it only takes a couple minutes to realize that the musical contribution these platforms are making is fundamental to the high-end experience. Townshend’s Seismic Isolation Podiums registered on my own personal Richter Scale like few so-called “accessories” I’ve ever experienced. And that, dear readers, amounts to an unshakable recommendation.

From The Audiophile Man:
If I could distill the Seismic Isolation Podium speaker stands down into one word, that word would be ‘organisation’. They not only bring order to the soundstage, they apply sense of understanding in terms of the instruments you hear. That is, each instrument makes more sense. When listening to a previously muddy piece of music, there is an element of “Oh, I see what they’re doing there now.” There’s a realisation. From an often confused mess, the Podiums bring an overall sense of clarity to any one track.

More than that, because you feel that you’re in good hands you find yourself relaxing and enjoying the music. There’s an expectation and excitement of what’s coming next instead of a fear that this or that frequency might be bright, sharp or one step away from sounding punch drunk.

More than any of this though, the Seismic Podiums allow your speakers to perform to the best of their ability. Grab yourself a pair of Podiums for your speakers and hear what those speakers – for better or for worse – are truly capable of doing. It’s my guess that yell be hearing them and I mean truly hearing them, for the very first time.

The most generous component in your hi-fi chain, Seismic Isolation Podiums spend their time making your speakers sound great.

GOOD: organised soundstage, low noise, midrange clarity, tonal realism, tweakbility, solid design

BAD: nothing

IsoAcoustics GAIA Isolators ($999/pair)
From Audioholics:
The one thing that my months-long experience with IsoAcoustics GAIA isolators taught me is that decoupling the speakers from the flooring substrate and dampening the resulting vibrations plays a role in improving the perceived soundstage, imaging detail, and improves the overall experience of the music. Moreover, isolation most certainly needs to be part of our conversation of optimizing speaker-room performance and as far as I'm concerned now belongs as an essential part of our optimization toolkit.

In every instance the GAIA isolators improved the top to bottom performance of my two reference setups.

The price point of the GAIA lineup is not for the faint of heart or wallet. In fact, implementing a stereo set of GAIA isolators into your setup may end up costing you somewhere in the neighborhood of 5%-20% of your speaker's MSRP.

Nevertheless, my experience with the GAIA was so overwhelmingly positive that I’m going to do something that I don’t often do with review gear—make it a permanent part of my personal setup going forward. This road with the GAIA was more of a personal journal than a formal review. Therefore, I highly recommend you take GAIA for a spin yourself and draw your own conclusions. But something tells me we just might find ourselves walking together on the same path to audiophile nirvana.

Finite-Elemente Cerabase ($1600/pair)
From Stereophile:
On the other hand, installing a set of Ceraball or Cerapuc feet under a component was a huge, jaw-dropping change. The differences were the same—improved focus, transparency, resolution, and dynamic precision—but their magnitude was much larger. Slipping a trio of Ceraballs under the VTL TL-7.5 wasn't like demagnetizing a cartridge; it was like upgrading to a really good moving-coil. And dressing cables? Forget it—this improvement was like replacing all of my freebie and Home Depot wire with a good set of high-end cables.

Like a kid in a candy store, I kept adding more and more Cera feet. The effects were similar with each step, and similarly dramatic. The biggest improvements came when I slipped Cerapucs under my VTL Ichiban power amplifiers and between my turntable stand's steel frame and marble top plate. The soundstage became significantly cleaner and the picture snapped into focus. Images inflated from two dimensions to three. The performers on Lakmé felt more like real performers in a real space than like a portrait. And when I played the Oscar Petersen Trio's Return Engagement (LP, Verve V3HB-8842) I noticed several dramatic improvements. Dynamic transients sounded 10–20% bigger, and the piano had much more inner detail and complexity and a richer, more distinct tonal balance. The bass was more powerful and much tighter.

Adding another set of Cera feet, or moving another component onto the Pagode HD07 rack, always improved the system's sound. The same was true for mixing the rack and the feet. The improvement due to the Cera feet was as large when I installed them between the component and the FE rack as when I put them between the component and a different rack. Moving a component onto the FE rack improved its sound even if it was already sitting on a trio of Ceraballs or Cerapucs. And for the coup de gras, replacing the HD07 rack's spike feet with heavy-duty Cerabases moved the system's performance up yet another notch.

I know vibrations and resonance can definitely affect equipment and speakers but these reviews make it look like a night and day difference. How can that be? Am curious from the folks here what they think.
 
Please stop creating such threads. We know there is tonnes of BS out there in the industry .it's kind of the point of the site . The answer to your headline question is invariably , 'no'.
