K22 - G4


The K22, with G4 Oladra technology, houses the Player and Re-clocker Engines of the K50, omitting only the K50's high-power Server engine. It can be used as a low-powered Server - Player - Re-clocker and be the ideal entry point when high-power is not needed. Or it can be added to the high-powered K41 to achieve the same performance level as a K50.


Antipodes Audio’s solution design

Why do I need a high-end music server/player?

"masters of ambiance and recreating the sense of artists being living-and-breathing entities, within a soundstage that breathes, moves, and flows”

"the K22 ticked so many of the same boxes of the [K41+K22] combo... it offers the exact same tonal balance and it sure wasn’t reducing the musicality or involvement... even in terms of resolution, transparency, and texturing, the K22-solo was not yielding to the combo.”


Implementation of G4 Oladra technology in the K22 in 2023 has transformed the K22 - treble and bass information is increased, the mid-range is enriched, and all sense of strain has been banished. Music flows with such ease that it conveys much more of the artistry and emotion in every recording, and will immerse you in your music. The K22 is designed to deliver world-class sound quality and outstanding value for users with libraries smaller than 8TB, and who do not wish to use DSP features.


The K22 uses a high-quality medium-powered processing engine that can run both Server applications and Player applications, together with the re-clocking engine from the widely acclaimed K50. The K22 can alternatively operate as a world-class Player-only device and is recommended for adding player end-points to an Oladra, K50 or K41, particularly when you can take advantage of the re-clocked outputs. The K22 engine plays to your DAC over USB, S/PDIF, AES3 and I2S, and can also stream via Ethernet over your network to streamers.


Vibration treatment is important in any high-end audio system, and any serious system is placed in a well-engineered rack. The same should apply to the equipment cases. They should be just as well engineered to deal with vibration, and we take that very seriously in every Antipodes model.

We also put a lot of design effort into the footers used on the Oladra, and this has trickled down to the benefit of all of the K series models in 2023. The footers include a special polymer that is specifically designed for vibration control, and the very detailed specifications provided by the manufacturer of this material allow us to precisely calculate the thickness to be used in each instance so that the pressure applied to the polymer is always precisely what is required for optimum vibration control performance. In the Oladra and the Performance Series the Polymer is used in a constrained layer damping design that makes it possible to tune each separate footer even more precisely to its optimum pressure, and allow a very small contact area with the equipment rack.


The following Server applications are pre-installed.

  • Squeeze Server 
    - customised version of Logitech Media Server
  • Roon Server 
    - industry-leading user interface and feature-set
  • HQPlayer Server Embedded 
    - industry-leading digital signal processing
  • MinimServer 
    - industry-leading DLNA/UPnP server
  • MiniDLNA 
    - light-weight DLNA/UPnP server
  • SONOS Server 
    - makes your music available to a SONOS network
  • PLEX Server 
    - widely-used and industry-leading a/v media server

Each Server application can play to compatible Streamers on your network. Both Roon Server and PLEX Server can also make your music available to your mobile devices on the move.

You can enable or disable as many as you need with a single click each, and they can play music concurrently. For simplicity, each application is pre-set to play from a common music library. Simply use the Antipodes File Manager application to drag and drop files to the Antipodes music library, and to include any directory on your network in the library. All music in the library becomes automatically available to all Server applications.


The table below summarises the Player(s) that can work with each Server.

Server Application Player Applications
Squeeze Server Squeeze Player
Roon Server Roon Player
Squeeze Player
HQPlayer Server/NAA
HQPlayer Server HQPlayer NAA
MinimServer MPD
SONOS Server No Players
PLEX Server No Players

Note that:

  1. Some solutions work differently, depending on whether the solution is on a single computer or spans two computers (the Server app and the Player app being on different devices), but the Antipodes Management Software (AMS) handles those issues automatically for you.
  2. Roon Server can be used with a range of Players, as shown in the table.
  3. MPD is also capable of playing music from a local library without the need to receive a stream from a server application.
  4. Antipodes music server/streamers do not have a SONOS or PLEX player application. SONOS and PLEX server apps are included for streaming to third-party SONOS or PLEX player devices.


You set the Playback Solution using AMS, which you can open from the Antipodes website, or using the My Antipodes application on your mobile device.

At the solution dashboard, click to display the Preset list (shown above) and click on the Preset solution you wish to use. In the same way, you can switch between Presets with a single click. In the image above, the K50 is currently set to use the Squeeze (Auto) preset and clicking on Roon (Auto), as highlighted, will change the Player application to Roon and the Server application to Roon, and you can then start using the Roon application on your desktop, laptop, tablet or smartphone to play music.
