I contacted Stack Audio, after the Vienna High End Show, to discuss using their products as an upgrade option on my new BAM40 and BAM20 Hi Fi racks. My BAM40 was on display in Vienna.
I had excellent feedback and discussions with them and I have just gained access to the whole range of Stack Audio Isolation products for the NZ market.
https://stackaudio.co.uk/
I will at least match their direct online pricing and possibly slightly better if you get hold of me to discuss.
Their most popular products are their AUVA Speaker Isolation Feet and their AUVA EQ Equipment Isolators.
The AUVA Speaker Isolation Feet are also entirely suitable as Isolation feet for Hi Fi and AV racks.
4 x of any of the 3 x AUVA Speaker Isolation Feet models will hold up to 274kg, so that will easily cover 95% of most folk's systems.
There are many Stack Audio reviews online. Here are a few YouTube and print ones and a lot of Stack Audio customer comments. You will struggle to find a bad review and don't have to look far to find extremely enthusiastic ones!.....
Shane (Aussie Audiophile) exclaims:
"they literally are the best footers I have ever heard in my 35 years of fiddling around with high end audio"
"Wow Wee!....BIG improvement....Wow, Wow, Wow!....this is next level, this is ridiculous....I don't know what to say, I'm lost for words....my system's never sounded so alive....it's mind bogglingly good!...."

"The AUVA 100's are an absolute "Thumbs Up" from me, these things are amazing....they literally are the best footers I have ever heard in my 35 years of fiddling around with high end audio....nothing has come close to what this stuff is doing...."

"The Stack Audio AUVA 100 profoundly impacted the loudspeaker’s performance. The music was more energised, more engaging and had considerably better separation and space around the instruments."

There is no shortage of alternative footers, but of all the variants I heard, whether hard, compliant-, or in-between solutions, none possess the AUVAs’ unique combination of skills.

"What these petite stunners do there simply feels far too substantial for the outlay involved, and that, to me, is the best thing about them."

"All I can say is WOW!!!"

Comments from Owners:
"AUVAs are superb without a doubt. I've had the 50, 70 and 100 under my Spendor D7.2 floorstanders. Found the 70 the sweetspot under the D7.2. I couldn't be without the AUVAs under any speaker I ever own - genuine A1 upgrade, equivalent to getting a better source, they are that good "
"For the money, 2 sets of 3 footers -$350; underneath my Tannoy Canterbury’s proving to be one hell of a bargain. Can you do better?.... I am sure you can, but count on being spending at least 2-4 times."
"I also replaced Herbies Giant Titanium Gliders under my Fyne F703s with the AUVA 70s. Amazing improvements in bass definition and extension, dynamics, soundstage depth and width and a vanishingly low noise floor without any hint of darkness...
"The AUVA 100s have certainly added a level of improvement and enjoyment to my music, subtle sometimes and not so subtle at other times, a nice improvement and investment."
"To say I’m gobsmacked is an extreme understatement.
I cannot believe the improvement the AUVA CSA’s have made, I thought I had a good sounding system before but this is next level times two."
"My racks are nice Australian made timber racks which are not vibration damped, so the AUVA EQs are a superb option in my system."
"The AUVA EQs are slowly infiltrating my system, added CSA-1 under my pre amp, the improvement is jaw dropping, I’m getting tired of wanting to listen to my entire collection each time I add these bloody things "
"The Antipodes has 'tuned' feet from factory. Curious as to how marked the improvement was with the AUVA added?"........."Massive, the biggest improvement of all my components."
"I did a direct comparison between the ISO acoustic Gaia Titans Theos and the Stack Audio Alva 100s on my channel. In my room with my gear there really was a clear advantage to the Stack Audio product."
"I agree both are very good and the ISO acoustic footers gave my Wilson's a big advantage over the factory spikes, but the Stack Audio footers have further improved that sonic presentation."
"My Stack Audio orders have all arrived........5 AUVA EQ under my Audio Research DSi 200 Integrated amp..........3 AUVA EQ under my Esoteric K-05XD SACD Player........and 4 AUVA 70 Isolators under my Wilson Benesch Vector Floorstanders.......results are excellent so far in particular the AUVA 70's......... transformed the performance of my Vectors. Need to let things settle with so many changes but so far I am very impressed."
"I got my AUVA 100’s a few days ago.
They have exceeded my expectations - by a LONG way.
On my ATC SCM100 ASLT they have noticeably tightened up and cleaned up the bass. The Alan Sircom HIFI+ review was spot on and explains it better than I’m able too.
https://hifiplus.com/articles/stack-audio-auva-100-loudspeaker-isolators/
"OMG these 100’s….. every metric that I value in music is noticeable better......Then they just open up with more bass articulation and punch that wasn’t there before......Amazing product, I’ve ordered AUVA EQ for my components I’m that impressed."
I completely agree with the above HiFi+ review.
In that you don’t really think that you have one note bass from your speakers - until you put AUVA 100’s on them.
Then they just open up with more bass articulation and punch that wasn’t there before.
The PR&T is noticeable better as well.
Amazing product, I’ve ordered AUVA EQ for my components I’m that impressed.
"....the AUVA 70's were really excellent but the AUVA 100's are something else again. Basically my Wilson Benesch Vectors are performing at a new much higher level"
"The AUVA 100’s under my ATC active 100’s are simply sublime.
For the price I paid, it was an upgrade like a new DAC or preamp. level quality - to me anyway.
I was actually shocked at the upgrade delivered for the price I paid."
"I can’t recommend this enough. Aussie Audiophile was right in claiming this as a really astounding product, equal or exceeding a component level upgrade."
"I don’t understand how the Auva 100 would have an effect on the presentation of higher frequency notes from the speakers..... I hear massive improvements from a solo female vocalist despite the absence of any low frequency bass notes."
"I too have the AUVA 100's on my Wilson Benesch Vector Floorstanders (31 KG).....likewise have no idea how they perform their magic. Made the mistake of taking them off my speakers......not recommended at all. The loss of system sound quality was nasty"
"If you are in the throes of "upgraditis".....I would put adding Stack Audio AUVA loudspeaker isolators at the top of your list......the increase in system sound quality is quite remarkable."
"Compared to the IsoAcoustics Orea Graphites, the Auvas impart a more natural, richer and open tonality. Noise-floor is similarly low."
NZ Owner:
"I've just had a significant change putting everything on that rack on Stack Audio isolators. Part of what they are doing is dealing with a system on the second floor of a wood framed house of course."..........
"I was astonished by the difference 12 isolators made. Probably vibration in the house structure whenever there is wind"
