    The Emperor’s New ClothesAlthough I am by nature skeptical that an add-on like speaker feet will “transform” an audio system, some such products have proven to be pleasant surprises. I have to admit that I can hear the difference that adding a Furman power conditioner made, and I am convinced that better speaker wires made a noticeable difference in my system’s sound. However, I do not believe that my Revel F226Be speakers sound any different with the IsoAcoustics Gaia III feet installed than they sounded without them, and to make matters worse, the feet were unnecessarily difficult to install.Let’s start with the design glitches. The feet screw into the bottoms of your speakers and are secured against the speaker bottom with a thin knurled ring nut. The nuts are thin because for stability purposes you want to screw the feet in as far as possible, leaving very little space for the nut (and consequently for the tool that tightens the nut) between the bottom of the speaker and the top of the foot. The instructions tell you to use needle-nosed pliers wrapped with a cloth to tighten the nuts, but if you can get those ring nuts securely tightened in that tiny space with that particular tool, then you are a better person than I am. Installation would be much easier if IsoAcoustics used thin hex nuts instead of ring nuts and included a thin wrench for tightening those hex nuts. This represents a superior design primarily because, unlike pliers on a ring nut, a wrench will grip a hex nut securely without slipping.The other design oddity is that the feet are supposed to be installed with the writing on them facing forward. This means that the feet should only be screwed in an integral number of turns, which makes it nearly impossible to get the speaker leveled and stable. Consequently, my speakers don’t feel solidly anchored to the ground but rather rock slightly. Now, I definitely want my speakers to “rock,” but not in a way that undermines a firm connection between speaker and floor.After sweating and wrestling for about an hour to get the feet installed so that the speakers wobbled as little as possible, I expected to hear a difference in performance. Nothing. No “tighter bass,” no “improved sound clarity.” Admittedly, it is hard to make an A-B comparison unless, of course, you have 2 sets of speakers that are identical except that one pair has the feet installed and the other doesn’t. Even so, I would be willing to bet that with my system in particular, most people who took a blind listening test would not be able to tell the difference between speakers with the Gaia III’s and otherwise identical speakers without them.The Gaia III’s come highly recommended by people with impressive audio credentials, and it was that positive press that led me to try them. I bought them hoping that they would provide both a noticeable improvement in sound and an effective way to level my speakers. They did neither. After owning them for several months, I consider them to represent the worst $400 I have ever spent on audio equipment. I could have returned them but didn’t, and I accept that as my mistake. However, I feel that they are poorly designed and do not perform as hyped, and I wish that I had admitted this to myself earlier than I did. If you want to try them anyway, I would advise you to buy them from a dealer with a generous return policy and that you focus on what you actually hear (or don’t hear) rather than what others tell you that you are supposed to hear. Don’t assume that merely because the Gaia III’s are expensive and have some high ratings that they will improve your system in your listening space. And, oh yes, be sure to allow plenty of time for installation.

    Don’t try this at homeI have been an audiophile and DIYr for 60 years. This product is one of the most frustrating ones I have ever had the misfortune to attempt to assemble. First, you can only install them if your speakers have footers that can be removed. Second, once you remove yours, you need wood inserts and holes into which to screw these footers that match one of the 4 sizes that come with this product. If your original footers do not have inserts, you must drill a hole commensurate with the size screw you have chosen for the weight of your speakers. Third, don’t expect your local hardware store to have the metric/SAE size you need. Forth, if you’ve gotten this far, and are screwing in the new footers, the insert will likely grind the walls of the hole you just drilled and turn with each turn of the supplied footer screws, meaning you will not likely get 8 of them screwed tight to the base of your speakers. Fifth, you will spend (waste) quite some time trying to figure out why you were supplied with a box wrench for round washers. Sixth, if you think all you need to do to improve the sound in your room is to tweak the hight of the footers, you have not fully grasped the number one law of home stereo equipment–the room in which your system is planted is the final immutable determination of the sound in your room. There is only so much you can do to improve that sound to your liking, especially when these footers might/or is likely to change your “sweet spot”, e.g. where the tweeters now catch your ear. However, if you really want to spend a lot of money to keep your hardwood floors from getting scratched, go for it.

    Amazing product.MOTHER OF GOD what an improvement. I have excellent quality cables, power filtering, an audio grade outlet and room treatments which all together combine to produce excellent sound quality. However there was a layer of haze I just couldn’t get rid of no matter what I tried. Particularly in the low end area. These gorgeous little feet got rid of that layer while cleaning up the entire atmosphere more than I could have possibly imagined. The largest immediately noticeable effect was the taming of bass bloating and low end clarity. I’m taking clarity like never before. Clarity like my speakers magically grew an additional transducer. The bass clean up was also noticed by my father who lives below me. He reported the low end vibrations and noise have nearly been completely removed. That alone is a powerful point for the Gaia III effect.I don’t want to go on and on about enhanced audio quality that you reading this have no real meter to gauge these improvements on, nor what the sound quality was before the Gaia III, but I will strongly recommend these feet for your tower speakers no matter what their price point might be.If anything these feet might be better suited for typical consumer tower speakers as opposed to exotic tower speakers being that less attention has gone into a typical pair of towers to eliminate internal distortions, excess vibrations, bass bloating, midrange smearing etc. It is here the the Gaia III can really strut their stuff with lots to chew on if know what I mean.I have these feet on my JBL Studio 190 towers which while current ( before everybody shunned them for their appearance without ever listening to them ) cost just $100 more than the Gaia III feet do.The Gaia III feet have been the finest $400 I have spent on my audio set up. If you have no plans on changing out your tower speakers but want clarity like you’ve never heard from your current speakers the Gaia III is your answer.According to the literature the Gaia III feet come with the weight capacity is 60 lbs, not 70 lbs.

    Expensive but easy to install and seems to improve speaker bass response and soundstageThe Iso Accoustic Gaia lll speaker (and speaker stand) isolation feet receive good reviews from many respected HI-Fi publications and Youtube HI-Fi / Audio reviewers. However, at £400 per set of 8 (i.e. 4 per speaker or stand) they don’t represent a particularly cheap upgrade and I have never seen them being offered at a discount, by any supplier.Regardless however, I decided to treat myself to a set of these over Christmas for a couple of reasons. Firstly, as my speakers are KEF LS50 Wireless lls, there is essentially no other upgrade path (other than adding a sub-woofer at even greater expense) because all the electronics are contained within the speaker cabinets, including 380 watts of amplification per speaker, DACs and streaming module.Secondly, the dedicated KEF S2 stands upon which my speakers are mounted are supplied with spikes, together with little steel cups that are intended to protect the surface of one’s hard floors. Unfortunately however, if the speakers are either moved or inadvertently knocked, its a real faff to reposition the steel cups beneath the spikes. So substituting the Gaia llls for the standard KEF spikes and cups makes it so much easier to move or reposition the speakers, as the Gaias are permanently screwed into the base of the stands.In terms of any improvements in sound quality as a result of installing the Gaias , as I have only just installed them, it’s quite difficult to say. This is especially so because the possibility of a normal punter like me performing an A / B comparison in one’s own home or listening environment is virtually impossible without having 2 identical sets of speakers (and stands) available (one with the Gaias fitted and one without). However although I can’t be absolutely certain after the minimal testing I have carried out so far, the bass response of my speakers seems to have improved a little and the soundstaging also appears to have improved, with greater clarity in terms of instrument separation and positioning etc.Obviously, I’ll get a clearer impression after conducting further listening tests (at higher volumes when my wife is out!) but so far, so good (I think!).One last positive benefit is that once fitted, the Gaias look quite cool, with their dark chrome finish blending in very well with the grey finish of my speakers and stands!If you’re thinking of purchasing the Gaias, its worth watching the A / B test carried out by Terry Ellis on the “Pursuit Perfect Systems” YouTube channel. Admittedly the test was carried out using absolutely top-notch audio kit that would probably be far beyond the budget of most people, but this demonstration does provide some indication of the sound improvement that installing Gaia Isolation feet can produce.

    These are Most Certainly Worth the MoneyMoving house recently has necessitated re-positioning of my heavy floor standing speakers. Unfortunately the room dimensions in my new home affected the sound quality and although I spent a lot of time altering the position (toe-in, back and side wall to speaker distances) of the speakers, I still had a problem with a slightly woolly bass and mid range fidelity. The speakers are on granite plinths which are in turn spiked through thick carpet to the concrete floor. Reading the reviews, especially the EISA recommendation, of various sound insulation gizmos, I decided on IsoAcoustic Gaia 11 pucks. I was amazed at the difference these units made; gone is the woolly bass distortion and the overall clarity of the sound stage is staggering. These Gaia’s are worth every penny and I recommend them whole heartedly.

    Pricey but wow what a differencePreviously used a variety of spikes and cups on a wood floorThen used the isoacoustics LS-155 small monitor stands which were a good improvementAfter a while debating these because of the price pushed the button and…..Wow just wow, my Quad 22L2 floorstanders have a new lease on life.Soundstage much improved, noise floor improved, overall worth the money if a bit of a luxury

    Wow wow wowWhere to start , I was a skeptic not anymore, my gear, speakers ATC SMC40 passive, Amp Music Fidelity A5 heavely modified, Music Fidelity A5 CD player used as a transport running into Chord 2Qute with Russ Andrews liner power supply and Russ Andrews power cables and Chord speaker cables so a pretty good system, I had read several positive reviews so thought I would give these speaker isolation gadgets ago after all I can always send them back , well let me tell you theres not a chance that’s going to happen ! Improvements , bass definition has taken a massive leap forward more bass less distortion with loads of separation more definition , treble detail again is in a different class you hear details that just didnt exist before, timbre is laid bare, midrange is sweeter and seems further forward but in a good way less forced , Dynamics taken to another level and more expressive, the whole picture is on a another level and that sound stage is just so focused , I cant reccomend these enough ,if you have decent equipment go and buy with confidence, you wont be disappointed in any way they really let your speakers sing and more importantly your music purr like a pussy cat that just had catnip, Buy you wont regret it , I’ve just ordered more goodies from Isoaccustics, amp and cd isolation pods ,Enough Said.

    Allows you to hear more of the musical message the aritist intended when making the recording.Dramatically improved the focus, imaging and sound stage of my floor standing speakers and much more. Opens up the music so that you hear more detail, greater depth, better timing and rhythm, including improved control; an education. Far better than standard spikes. Works on carpeted wooden floor boards and the pile of my carpet is around 7 mm; a pile thickness that is probably around the norm. However, IsoAcoustics don’t recommend the pucks on deep pile carpet without the additional plate spikes – which the pucks stand on – so if you have deep pile carpet the cost increases.Are the pucks worth the investment? I would say yes. Probably the best performance per pound of investment you could make, since you get far more out of the system you have without upgrading with better cables etc.
