Stack Audio Anmeldelser 

I now own nearly everything that Stack Audio makes. I have several sets of the Auva EQ's, the subwoofer EQ's, and the Serene Mat & Stabilizer. I recently purchased the Auva platform to go under my turntable. The difference was apparent in the first few seconds of music. Everything improved in a dramatic way. Imaging and detail were much sharper, soundstage was both wider and deeper, the sound was more dynamic and the bass had more solidity. I was using other products that the Stack Audio products replaced and in every case the Stack products were superior, and not in a small way.

An extremely well made product that is well thought out and flexible in its application. I purchased two of the platforms to support a Grimm MU2 streamer/DAC and an Atoll DR400 Evo CD transport. It has exceptionally well done packing and installation instructions and was shipped promptly after my order. It has made a significant improvement in the overall sound quality of an already very good set up. I highly recommend this product. I would like to see additional platform sizes to accommodate larger components.

I have eq's under my rega planar 8 and my puresound p10 phono stage....excellent.....now i have auva 50's under my proac db1's on custom design stands....josh helped me with which spikes i need.....i was dumbstruck with the difference they made...i was dubious about spending over £400 on feet but best improvement ive had in years

Due to a technical hitch and delays at the post office the AUVA 50’s took a little longer to arrive than expected but my dealings with Dan were first class and he gave exceptional customer service, and I have to say it was worth the wait. The difference in sound quality was immediately palpable. I was honestly shocked by how much more focused the speakers were, the instruments were better placed in the sound stage and little details within the music became much easier to pick out. I am still shocked by the improvement they have brought to what I thought was an already impressive system and I recommend them without reservation. Well done Stack Audio and thank you for designing such a fabulous product.

I purchased a Serene Mat for my Denon DP 3000 NE. I am using a Hana ML cartridge through a McIntosh MAC 7200 amp and Sonus Faber Sonetto V speakers. Also REL G2 sub. The Serene Mat replaced a Project Leather-it Mat. Two main observations: Substantially improved bass. Less "boomy" and more precise. And, background noise is virtually absent. It was low before, but undetectable now. I absolutely recommend this product, and appreciated the great service from Stack Audio.

Perfect isolation for a bit heavier speaker. Brings in all imaginable improvements one would expect. Black background, improved transients and clarity. Fast delivery.

I have now purchased several items from Stack Audio. Purchases are sent without delay and are always superbly packaged. I strongly recommend this business and won’t hesitate to use again. Best if all, their products do exactly what’s claimed and they have certainly enhanced my listening experience. Think of their accessories as the icing on the cake plus lots of cherries.

Bought Dali floor standers coming from book shelf’s. I was quite disappointed and didn’t realize the acoustics I have. At low volumes they were amazing I could hear that but above 40 no good not even close to my 20+ years old speakers. Decided to try the Auva 50’s and honestly can’t really still believe they became different speakers altogether. Clarity, detail and control of bass. I can’t explain it you would have to hear it for yourself. If you have muddy or “thumpy” bass and therefore lack of mids and highs these will clear that up and they do an amazing job. I have been back and forth with Josh for 3 weeks probably driving him bunkers. In my experience there’s very few places, if any, with this level of customer service. Amazing!

Wonderful responsive service from Josh, Dan and all at Stack when I needed longer length spikes for my Auva 70. Virtually next day delivery w/superb comms. The Auva speaker 'pucks' have truly been superb under my B&W 805 D3 - the soundstage has opened up with more layers, the bass has become tuneful and very solid, and the music has stepped free of the drivers - more 3-D and in the room. Guitars have bite, decay, verve and with metal-strung ones a superb edge. Drums are more natural and again decay more naturally. Voices: just beautiful! Orchestral music has body, weight and power. Delightful: a joy to listen. I already had the Serene mat & stabiliser on my LP12, and hoped for similar effects with the Auva. Got that, in spades. Highly, highly Recommended!

I read the FairAudio review of the SmoothLAN products in your February newsletter, and being fairly new to digital streaming became curious about them. Other online reviews were also very positive. Since I’ve enjoyed success with your AUVA 100s, 70s and EQs, I decided to order the Regenerator. The product is absolutely amazing. The FairAudio review is spot on. There was a very pleasant immediate improvement in clarity, energy, presence and detail in the music coming via Qobuz through my pretty modest Cambridge Audio streamer and older W4S DAC. You hear and actually feel the difference. Great product well worth the investment.

As a long-time enthusiast, I am rarely surprised, but the impact of Stack Audio’s AUVA technology on my system has been a revelation.
I first installed the AUVA 70 isolators under my Wilson Audio The watt Puppy 2024. The transformation was staggering. The bass response became ferocious, lightning-fast, and incredibly powerful, yet perfectly controlled. The AUVA 70s provided a rock-solid foundation that eliminated any cabinet-room smear, delivering a sense of materiality and texture I hadn't experienced before. The note decay is now fantastic—natural and lingering exactly as it should be, allowing the speakers to disappear into a surgically precise soundstage.
Encouraged by this, I used the AUVA EQ (CSA 3) under my Halcro DM 88 electronics. These amplifiers are world-renowned for their ultra-low distortion, and the AUVA EQ managed to lower the noise floor even further. Micro-details now emerge from a 'jet-black' background with effortless clarity and a tangible, organic presence.
Beyond the engineering excellence, the human element makes Stack Audio stand out. Josh provided world-class support—professional, passionate, and genuinely interested in my setup’s results. If you own high-resolution gear like Wilson and Halcro, these AUVA upgrades are essential.

Just added AUVA EQs for under my Rogue RP5 tube preamp and Hegel Viking CD player, and they're a high value, truly excellent addition to enhance my audio system. After reading and watching many reviews, all of which have been positive, expectations were high, for sure. But after fairly intense critical listening over several days, I can honestly say that I'm very happy with the results. The music sounds clearer, more defined, more quiet and the decays are more prominent. Bass is tighter and more clearly defined. I would have to say that the magnitude of the improvement is at the level of upgrading a component, certainly more significant than upgrading cables. At this price point, no one should hesitate to add these to their audio system. I'm now looking forward to adding AUVA 100's for my Focal Sopra 2 speakers as a next step. Dealing with Stack Audio has been a pleasure. Josh is patient, responsive, timely and helpful in his guidance, which made the purchase experience even more enjoyable. This is an extraordinary company that offers great products with a level of service and responsiveness not seen often enough in today's world.

I reached out to Stack Audio and requested 2 x sets of 4 threaded inserts for my Auva 70 feet as the ones i had for my last speakers would not fit my recently ordered new ones.I sent an email to them and the very next day they arrived.To say i was delighted is an understatment.Now i just have to wait for my speakers to arrive with the confidence that these footer will work there magic on them also.With my old speakers on a floating wooden floor the Auva 70 stopped the floor reacting like a giant drum skin resulting in blackness to the sound that encouraged more midrange and low end detail to come through i quickly realised my speakers had much greater control this resulted in a more relaxed and altogether more enjoyable sound that i wanted to listen to for hours on end.
Thank you Stack Audio.

Having purchased new speakers I contacted Stack Audio and requested new studs to connect my Auva 50s to the base of my new speakers as the thread size was different between manufacturers.They arrived the following morning.I connected them up as I knew they made a huge difference on my last speakers.The difference in sound is immediate.i have a wooden floor, but they are designed to my used on a carpet if required.Using these Auva,s cleaned up the base and let me hear more of the music.I can’t stop smiling.Ambient music there is more airiness, with jazz you can hear more suttle changes.

Having researched ways to improve my system I invested in the Serene Stabiliser and a set of AUVA 70 Isolators for my KEF LS60s. The overall improvements in the sound stage, dynamics and depth are astonishing. If you want to get the best out of your system then look no further. I have just ordered a set of EQ Isolators and look forward to even more sonic delights. Customer service is exemplary and Josh could not have been more helpful in providing advice and guidance when dealing with my queries. Highly recommended.

I’ve made a few changes to my setup at the same time so in terms of sonics specifically related to the SERENE I’m not entirely sure. I was after a quality rubber mat and it’s certainly that so very happy with my purchase and I am enjoying a more detailed sound with a livelier bottom end than I had before.

I now own thier Auva 100 speaker footers, a set of Auva EQ's for my DAC, a Serene Stabilizer and a Serene Matt. These are fantastic products, and have led me to begin replacing my Isoacoustic feet. The customer service is second to none--Josh has been beyond accommodating, dealing with our President's ridiculous tariffs. I really couldn't recommend them more highly. Next up: 2 sets of the Auva SW's for my subwoofers

I have used Stack Audio for several years now and have tried all the various Auva Speaker and Equipment technologies. Without fail all their products have improved my listening experience. The Auva Speaker components for both main speakers and subwoofers are essential in any system and will let speakers and subwoofers perform at their best - I have seen this first hand across Q Acoustics, Amphion, REL and Alta Audio speakers. For truly squeezing the last out of your digital components the Equipment isolators work well to improve imaging, soundstage and background quietness. On top of all of this, the customer service is friendly, efficient and second to none and there is a 60 day trial period. A no-brainer for any serious audiophile

First the communication with Stack Audio is fantastic.
Quick and adequate answers.

Then the product are really doing what is sayed on there web site.

I ohne the AUVA50, the AUVA EQ's and the Serine Mat and Stabilizer and al doing a suppurb job.

I have purchased many Stack Audio products over the years. I am currently using Auva 50’s below my speaker stands, Auva EQ’s below my amplifier and CD player. I am also using the Serene Mat & Serene Stabiliser on my Linn LP12 record player. My Linn L12 also benefits from several earlier Stack Audio products, the Stack Alto sub-chassis, arm-board and cross brace together with a Stack Ultimate baseboard.
Each and every one of these Stack Audio products has added a beneficial improvement to my Hi-Fi system and improved the soundstage along with my listening enjoyment.
Josh & Theo have been an absolute pleasure to deal with. Customer service has been first class.
Stack Audio UK is a small British business that simply excels in its product offering and support..
Highly recommended indeed…
