What they say ...


Ed Selley  |  HiFi Choice

The Zenith Mk3 delivers a potent and flexible specification, with one of the best interfaces going ... and is compatible with Roon front ends. The price may be high, but it delivers an outstanding performance that will inspire confidence even for those starting out in network audio, and so should be near the top of any shortlist.

Hans Beekhuyzen has followed up on his comprehensive ZEN Mk3 video review by taking a look at the next model up in the range - the ZENith Mk3.

"The Innuos ZENith Mk3 is the ZEN Mk3 on steroids. It is also a one box server/streamer solution of high quality"


"It keeps surprising me to what degree sound quality can be improved by taking more care when sending a digital signal over USB to a DAC - and the ZENith Mk3 does a damn good job doing just that."

"Audio playback based on files came a long way since its infancy days.

Early machines designed with this task prioritized were troublesome, sounded nowhere near as good as they do now, didn’t look as nice, surely weren’t as stable, and required quite the know-how to handle. It took years, but finally this inaccessible geeky stuff blossomed into easy to use versatile audiophile packages such as today’s. Innuos ZENith Mk3 not only is a fine example of how it should be done, but it also emerged as the most accomplished of its kind I came across.


Many network audio devices gladly rely on buttons and displays, however Innuos ZENith Mk3 renders them unnecessary and on functionality ticks all checkboxes with no questions asked. Its minimalist bling-free modern look scores high by my standards and so does assembly. Today’s goes the extra mile with its ripping drive, fully embedded Roon platform, broad compliance with other devices, and hassle-free operation. Keen execution of all tasks without hiccups, nearly instant readiness and overall stability are clear indicators of thoroughly polished engineering work, which is admirable. Considering all this, very shortly I stopped missing UPnP rendering.


Innuos ZENith Mk3 on functionality shines as brightly as it does on sonic performance. All its noise removal traits kept the usual digital culprits at the door and provided firm substructure for tonal evenness, fluency, spatial might and wide dynamic contrasts, which in effect resulted in aural experience many seasoned aficionados would associate with costly boutique music boxes and not PCs. But overall balance is where Innuos ZENith Mk3 truly excels. Not only it finely connects audiophile sonics with mainstream needs, but also is priced attractively considering what it does and how"
