Highest playback quality on a PC, remote app on a tablet

JPLAY FEMTO is a complete network music software player created by fanatical audiophiles for the most demanding audiophiles.

The word ‘network’ does not imply that music files must be streamed over network. In contrary – it means that the best sound quality can be achieved by playing files that are stored directly on a PC which connects to a USB DAC.  Utilising network brings convenience that has not been available in the past with any JPLAY release; sitting relaxed on a couch and controlling playback by a remote app on a tablet or smartphone. Without touching the PC.

Getting started

  1. Download and run JPLAY FEMTO setup on a Windows PC that is connected to your USB DAC. The PC must be connected to Internet and home network’s WiFi. Windows 8 or later is required.

  2. Select the folders with your music files during JPLAY FEMTO setup.

  3. After successful installation restart PC. (this is mandatory)

  4. Make sure you have the latest driver installed for your USB DAC. (The built-in Windows USB Audio Class 2.0 driver is not compatible with JPLAY!)

  5. From Start Menu – Programs – JPLAY, open ‘JPLAY Settings panel’ to select your output device (‘Playing via’ field). By default the output is set to the best sounding playback method, KS (Kernel Streaming).

  6. Open a UPnP remote app on a tablet or smartphone connected to your home network’s WiFi; JPLAY for iOS  is highly recommended! , select JPLAY FEMTO as the renderer and JPLAY femtoServer as the library

  7. Voila! You can now play your music files at the highest possible sound quality.

Thanks to HIFY app on Android it is possible to select JPLAY FEMTO as output in the official Spotify client.

All you need is an Android device (tablet or smartphone) with running HIFY app


Once the HIFY app is launched, JPLAY FEMTO shows up in any spotify client running in your network – on Android, iOS, MacOS or Windows. Below is a screenshot of the spotify app running on my Macbook Pro. As you can see, JPLAY FEMTO is listed as a ‘spotify connect’ device.
