The DSD upgrade is now available for all previous versions of the QB9. 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.
“Providing significantly greater performance than any similarly or lower-priced alternative, and undoubtedly one of the best computer-audio DACs now available regardless of price…”
– Pete Roth, Ultra Audio
