Litemedia – AUVA 70

Litemedia – AUVA 70

“Thanks to greater accuracy, the music gains coherence and timing, increasing dynamic range and providing more freshness and vibrancy. Singers and instruments have greater presence and body. Furthermore, the 3D representation is more immersive. The increased spatiality is accompanied by greater openness and airiness. Thus, the AUVA 70 offers a significant performance boost and, considering the sonic improvement, is truly excellent value. Highly recommended!” Read more by clicking here .

HiFi.NL – AUVA Platform

“Wherever I deployed the AUVA, the reproduction consistently improved. In the silence in the background. In the tranquillity imparted to the system. Especially in the stereo image, which gained depth and height, and could just as easily become wider. Also in naturalness, detail, and spatiality, in which, for example, reverb was given the time to slowly fade into the background. Voices lost a ragged edge, even if that wasn’t really noticeable before; instruments detached more from the harmonic overtones they produce.”

HiFi+ – SERENE Stabiliser Editor's Choice Award

On the Rega Planar 10: “The Stack Audio Serene enhanced the ability to refine fine detail. From the midrange upwards, there is more information to discern.” Their final verdict? The Serene “greatly expands the range of situations where these devices can be effective and offers them at a very competitive price.” Thank you to Hi-Fi+ for publishing their SERENE Stabiliser review! They put the Serene through its paces on a range of turntables, from the AVID Ingenium Twin to the Rega Planar 10 and Vertere DG-X, and found it enhanced fine detail and openness across the board, even on decks that “have not traditionally responded positively to anything placed on the record.”

Should You Isolate Your HiFi Rack? Why Rack Vibration Matters

Should You Isolate Your HiFi Rack? Why Rack Vibration Matters

A lot of isolation conversations start and end at the speakers. That’s for good reason: a loudspeaker is the most energetic source of vibration in most rooms, and getting it decoupled from the floor is the first and most important thing any system can do.

Controlled Compliance: Why Your Equipment Needs A Different Kind Of Isolation

Controlled Compliance: Why Your Equipment Needs A Different Kind Of Isolation

Rigidity Solves One Problem. Compliance Solves Another. We’ve written elsewhere about why a loudspeaker cabinet needs to stay rigid: the short version is that a driver pushes against its cabinet to move air, so the cabinet has to hold its position for that motion to translate cleanly into sound. Ele

Australian Fulfilment Centre – Now Live

Australian Fulfilment Centre – Now Live

We are pleased to announce that our Australian Fulfilment Centre is now live. Until now, ordering from the UK as an Australian customer meant your final price could shift depending on import duties, GST, and processing fees applied at the border, and delivery meant a long international shipment before your gear even reached you. That changes today. We’ve moved to a single, all-in Australian price for every product, a flat adjustment that covers GST, import handling, and processing costs upfront. What you see at checkout is what you pay. No calculations, no “estimated” fees, no invoice arriving weeks later asking for more. That price also gets you same-day free shipping from our Australian fulfilment centre, not the UK, so your AUVA, SERENE, or SmoothLAN product reaches you faster and clears without customs delays. And if you ever need to return something, it’s handled entirely within Australia, including the return shipping cost, on us. One clear price, faster delivery, and easier returns, without the guesswork that used to come with ordering internationally.

Stereonet – AUVA SW

"Bass sounds cleaner, transients are sharper, and cabinet-induced colouration is convincingly reduced. I came to this product curious, and left convinced." Reviews of isolation products usually rest on listening impressions alone, so it was great to see StereoNET take measurements too. Accelerometer testing on the subwoofer cabinet, with and without the AUVA SW fitted. Cabinet vibration dropped by 75%.

The Science of Speaker Isolation: Why Neither Spikes nor Soft Isolation Are Perfect

HiFi Knights – AUVA EQ

"What these petite stunners do there feels far too substantial for the outlay involved, and that, to me, is the best thing about them. Considering how the Auva EQ behaves under electronics, and how effective it is in that role, the asking sum feels almost like a misprint. What these petite stunners do there feels far too substantial for the outlay involved, and that, to me, is the best thing about them. While evaluating these, I found myself returning often to IDLES’ “Dancer”, and when the chorus goes “Collide us while we work it out”, I couldn’t help but picture their internal particles atop a silicone bed taking it personally and doing exactly that—quietly, relentlessly, and very much to our benefit."
