The DSD upgrade is now available for all previous versions of the QB-9 and DX-5. This upgrade not only allows for the playback of DSD files with computer audio, but it significantly improves the sound from any source through the analog outputs* of the player.
Due to the success of the QB-9 and DX-5 we have a large number of people patiently waiting for updates. If you would like to have your QB-9 or DX-5 updated, please contact your local dealer for pricing and to be placed on the waiting list.
* If you are only using the HDMI output of the DX-5 you will not hear a preformance improvement with this update.
