I've been reading and wondering about these for a year or so. These are isolation feet for speakers tuned for different weights of speakers.

Gaia three are the babies luckily for me as my cabinets weigh 17kg EA I didn't need to buy the much more expensive, larger Gaia's.

Interestingly for a non electronic piece of hifi hardware they received pretty much universal praise with similar sentiments being reported by different people in different places e.g. magazines to Amazon buyers.

I folded of course and bought a set, I got them for a bit less than RRP by messaging an ebay seller who always sells them.

So I attached them to my Dali iKON 6 Mkiis and had a listen...

RIGHT away bass is more impactful and cleaner. Things start and stop and have timbre to them. I'd guess it was 30-40% better than what I had and my GF noticed it right away (she has good ears growing up in the countryside she's not deaf like me!).

Then second thing I noticed, stereo image is much more focused and in the centre, it's like the room has been acoustically treated a notch.
This makes the speakers disappear more or in some songs completely, very nice as before I was always aware of my speakers.

Next thing to notice, spatial resolution and transient response. Especially in regard to higher pitch percussion any trailing edge smear is reduced, things start and stop are crisp and 3D soundstage extends to make things very nicely holographic. Depending on production value you can hear different instruments in fixed places in the air.

Everything is clearer, call it removing a haze if you like but things are closer to 'correct' now.

Something else to notice is during films the front soundstage is together more and cohesive. I have my centre channel raised on monitor foam wedges so is relatively isolated (highly recommend doing this too), now there is much less distinction in certain times between the front left and right speakers with the centre. Like additional timbre matching has occured.

So I'm waxing lyrical right? Guy spends stupid money on speakers feet and placebo effect wins the day? I don't think so. I was not sat there straining to hear these differences, they are there immediately and with no doubt.
All speakers idealise cabinet inertness, look at the Q acoustics concept 500 speakers (will buy these one day!) and the lengths designers went to to dampen the cabinet.
This can be considered hifi dogma and the Isoacoustics feet are allowing you to improve on this after the fact.

I would not be without these now and they do actually justify their price. Why?

Because in effect you have upgraded your speaker to a whole tier above at less money or when you don't want to/can't replace your speakers.

Think of it that way and you're doing good man maths now.

They look good but sound better. Highly recommended. My system is now a pleasure to listen to.
For those that want to know here's the chain.

Tidal Cd-quality--Sonos connect digital out--Arcam IrDAC analogue out--Yamaha A-S1100 integrated--Dali iKON 6 Mkiis + BK XXLS400 (X2) configured in stereo via high level with low pass @~50hz

RRP £200 for four. Amazon used to have them £180 for a while but alas no longer. That is the price I negotiated on eBay however so £360 all in.

Can't do high pass just low. I used an app called spectroid and an album on tidal that does test tones. My speakers did 50Hz fine then gave up at 40hz so set the sub so work at that range which seems to work well.

I'd love to not send any bass below 45hz or do to the mains but not possible with my gear setup.

I was on spikes which ultimately still couple to the ground underneath (concrete) in my case.

Per my review these things do work and are not BS.
They sell spiked shoes for carpets at £49.99 for four but for now I cba with those.

All things in hifi are expensive honestly. These make a great sonic impact that youd notice way before changing cables or the average DAC IMO.

The Isoacoustic isolators have to be orientated either logo facing out or 180 degrees to this. This is due to their design to reduce motion in certain directions.

They said they used a laser pointed at speaker cabinets to workout how best to reduce unwanted effects.
So the money here is R&D into an acoustically designed product. It's not bunging a speaker on some sorbathane.
 
Same principle as not having near field monitors on a desk with no isolation.

Newton's third law, no matter how you say a speaker cone is suspended it has mass and if it is made to move one way then the cabinet will go the other.

The change isolation makes must be small but audible and that's what any improvement in design is, improvement for improvements sake.

My system is a resolution monster now, (the Yamaha amp is an outstanding bargain IMO). To the point where you play a song you know well (pre Gaia), hear new things, install feet then hear new things on top of that.

Plus I saw them installed on a $1,000,000+ system on YT so must be good:D
 
Guys reason I made this review is that I had all these same doubts. I thought at first they were snake oil products, that they were a rip off.

It's a total leap of faith product I get that. But I've done a 180 on both the points above.
 
Thanks lucid you better explained it than I could. I have the review verbatim on the AV Forums right now, it's a far higher proportion of cynics on there.
In fact some of their replies make me inclined to never frequent there again, not because they disagree with me but their manner.

My line of work (healthcare/NHS use your imagination) means I am more formally versed than most about placebo. I see the effects of this first hand on a daily basis across thousands of interactions with people each year.

I am fairly resilient to placebo effect but am a human none the less.
Factor in psychoacoustics, an extremely interesting field where your measurements of objectivity mean nothing. It can pretty much be summed up as if you think it sounds better because of X or y then it IS better.

Another 'motive' for posting the review is I genuinely want people to consider them and use them, as lucid said it allows you to get the most from what you have.

I can't change my speakers as it's timbre matched to an IKon & Dali 7.2.4 surround setup. They have allowed my speakers to work at full capacity, coupled with robust amplification of course.

The only thing I can (and intend to do) next is acoustically treat my lounge.

As people have noticed yes you can obtain rubber or sorbathane easily and cheaply but then what? Are you going to produce your own feet? Can you beat something developed with laser interferometry? How much would all that time really cost you?

Again, take in Lucids post, design matters and now that my floorstanders float partially decoupled from the ground I can hear them sing.

Any of you with a centre channel put it on monitor foam wedges and tell me things aren't clearer and more resolved.

The argument of the driver mass not 'overcoming' cabinet mass is like saying your speakers are outside the realm of known physics. Or your speaker cabinet is a mountain. It will vibrate and resonate, less than mine I'm sure though

TBH a miniDSP UMIK-1 and REW should answer if the improvement is real or a placebo, around £100 if you fancy giving it a go, you will need a tripod though.
Have come close to getting a UMIK-1 before. Have a tripod but I'm not gonna do this as my thoughts on the feet have been made clear:)
 
Yes same brands for sure in surround is the only way I will do it but I've seen others mix and match and be happy.

I wonder if a speaker manufacturer released a speaker that had its plinth designed to decouple the speaker (stands on the high end Q acoustic bookshelves do this) and you bought said speaker and thought it sounded great.

Bet you any money if your mate asks you about your speakers you'll be sure to remember that they've been designed to be decoupled from the ground:)
 
Room acoustics are an inconvenient truth to Hi-Fi. Hardly anyone can or does treat their room when this represents nearly a half of what you hear.

It's not sexy tech and is more elusive. Doesn't mean it's not vitally important and ever present.
 
I auditioned a fair number of speakers when I bought the Ikons.

A set of regas bested everyone for seamlessness, truly astonishing crossover (very simple so I understand) and that sideways mounted bass driver. Like liquid music poured into your ears. They looked so utilitarian though!

Focal arias I forget which, 926? Then started sounding like 'proper hifi' speakers if you like but I think we're £1800+ for the pair and a surround setup using those would have been serious cash.
 
Reads like a Russ Andrews advert.

Can't chat though, I'm off to monopolise the transient inverse timbre on my plasma phased substrated flooring while revolutionising my timber impregnated laminar modular floor structure.

Then I'm moving onto spatialising my high concentration nitrogen rich atmosphere to reign in the floatational dust effect within the aurum of this reality, whilst ensuring I draw on the mass damping from additional realities whilst not displacing the martensite phase (body centred-cubic) within my superalloy stands, otherwise I'll phase shift the standing response of the bedrock and the house will fall into the sea.

I'll post some phase diagrams and quantum calcs shortly, I just need to calibrate my balsa wood ruler first.

Thanks buddy. How else would you like me to describe sound through the clumsy medium of written text?

What if I told you I play the piano to a good standard and can actually use my ears + brain to hear differences in sound?

Easy to criticise the man in the arena isn't it.
