Innuos Zenith MK 3

Music Server & Streamer

The Innuos Zenith Mk3 incorporates Innuos' EMI-treated Custom motherboard and premium Triple-Linear Power Supply. The new power supply features ultra-low noise regulators and Mundorf Capacitors, using trickle-down technology from the original ZENith SE. The internal SSD is also mounted and treated to avoid vibration and EMI interference. Strategically placed asymmetrical feet are now a standard feature of the ZENith as a result of the development of the feature for the original ZENith SE. The media streamer and server uses a Quad Core Intel PCU, and comes equipped with either 1, 2, 4 or 8TB of solid state SSD digital storage. The ZENith Mk3 also has a USB 3.0 connection in addition to the USB 2.0 and ethernet. A second ethernet connection allows direct ethernet streaming to another renderer.

Complete Streaming Solution For The Most Demanding Music Lover

" Drawing parallels with the vinyl world, a DAC is analogous to a phono pre-amplifier whilst the source device (PC/Mac/streamer) stands in for the turntable itself. Each part of the chain influences the audible outcome. Experience tells us what theory-fixated armchair pundits cannot: that everything matters." - John Darko, Digital Audio Review

"...Innuos has a music server/player that's very solidly made, attractively styled, super fast due to its SSD and a poster child for user friendliness and intuitive use. Particularly the browser interface makes chores like tags, rips, imports and backup scheduling easy as pie. This should be the gold standard...

...The Zenith MkII did aterrificjob as a career audiophile of purist leanings: tonally neutral, ultra resolved, rhythmically in the pocket and spatially dimensional. At its price, I'm not aware of competitors which objectively would be "more correct" - merely those that do it different if no better" - Sixmoons

Self Contained, Stable, Easy To Install & Use

What do I mean when I say the Innuos Zenith MK2 is self contained? It is a music streamer capable of running as a Roon server and player, it has built in storage of 1, 2, or 4 terabytes, it has a built in CD ripper and a universal web browser based interface for setup & library management. You can download, rip, store and play back your music files without the need for a NAS or server. This has another advantage of making the Innuos incredibly easy to set up.

Roon Ready

The Zenith MK2 is Roon ready, and capable of running as a Roon Server, Player or both. Quite amazing really, and it adds to the ease of use factor. There's no need for a NAS or another networked server. Your musiclibrary, music server, and streamer are contained in one component.

Intelligent CD Ripping

The Zenith MK2 offers Bit-Perfect RippingUsing AccurateStream technology. You can extract every last bit of your CDs into WAV or lossless FLAC files.

Automatic CD Ripping: Just pop-in a CD, the innuOS Zenith MK2 will automatically get full album data and cover art from multiple online databases, rip your CD and eject when done.

Assisted CD Ripping: Assisted CD Ripping allows you to see and edit all the album data and cover obtained from the online databases before you rip the CD. Great for Classical Music!

Quiet Mode: Love to listen to music while ripping your CDs and want absolute silence? Just engage Quiet Mode for slowing down ripping, making it much quieter and with less vibration.

Offline Ripping: CDs can be ripped without internet connection. When connected, album data and cover for all offline ripped CDs will be obtained with a simple click.

Digital Music Importing

Import Wizards for Existing Libraries: The Zenith MK2 has pre-defined wizards for importing music from USB storage, Music Servers and NAS.

Intelligent Import Engine:TheinnuOS streamer takes all the hard work of importing music by intelligently analysing the music files and applying a number of rules such as:

  • Organizing the music based on format quality (compressed, cd quality or high-resolution), Artist and Album
  • Removing very long file names or illegal characters
  • Adding metadata to WAV files based on folder structure

Download from Online Stores:Qobuz, Linn Records, HD Tracks, HiResAudio, B&W Society of Sound, iTunes, Amazon and more. Just download the music files (even if they are in a zip or tar file) to the Auto Import shared folder and the server will take care of adding and updating the music library.

"Precisely because the interface was browser-based, I didn't have to fire up a PC/Mac or install an app. Any smartphone or tablet can tag/import files, rip CDs and set up backups. So intuitive was this interface that any additional words on my part would only make it more complicated." - Sixmoons

Music Library Management

Edit or Delete Albums:Browse your library, select the album you want to update and just start editing directly on your tablet or smartphone. You can change the cover, manage genres based on previously used genres or simply delete the album - couldn’t be easier.

Quarantine:Quarantine is a staging area, separate from the Music Library, where any albums requiring attention are placed so they can be fixed before they go into the Music Library. These include:

  • Albums with no metadata
  • Ripped albums with damaged tracks
  • Potentially duplicated albums
  • Albums ripped offline

Automatic Music Library Update:After music is added, modified or deleted, the library is automatically updated as well as any connected systems such as Sonos or UPnP Streamers.

Music Server Management

Automatic Network Identification:No more figuring out IP addresses find your server. Just go to on your tablet or smartphone to list all Innuos devices on the network and access the innuOS App from there.

Remote Updates:Update the system with a touch of a button to benefit from our continuous improvements: new functionalities, enriched customer experience or enhanced sound quality.

Automatic Backup to USB Drive or NAS:Backup of your music library can be set on innuOS to start automatically based on library growth (e.g. every time 50 CDs are added) to either a USB backup drive or to a NAS on the network.

Rediscover your existing music collection, discover new music:Play all your music as well as Internet Radio and streaming services with the best sound quality by connecting directly to a DAC or Digital Amplifier via asynchronous USB.
