Onkyo & Pioneer Corporation has released a firmware update for certain network A/V receivers and stereo receivers enabling DTS Play-Fi’s ‘Critical Listening’ mode supporting Hi-Res Audio streaming up to 192 kHz/24-bit in resolution, via services such as Amazon Music HD and Qobuz. Content from Media Servers (NAS) or local storage on Android and iOS devices can also be played via compatible Play-Fi Apps such as Onkyo Music Control and Pioneer Music Control.

Firmware for DTS Play-Fi Critical Listening mode is available for these models:


Network A/V Receiver TX-RZ840, TX-RZ740, TX-NR797, TX-NR696

Network Stereo Receiver TX-8390


Network A/V Receiver SC-LX904, SC-LX704, VSX-LX504, VSX-LX304

Play-Fi usually plays music streams in their native format and encoding. Hi-Res Audio, however, is down-sampled to CD quality to maintain compatibility across products within the ecosystem. When using Critical Listening mode with supported products, Hi-Res Audio, up to 192 kHz/24-bit resolution, is streamed without down-sampling or re-sampling, delivering “bit-perfect audio with full signal integrity.”

Firmware can be downloaded and installed directly on network-connected components, or downloaded to USB memory from the Onkyo or Pioneer website and installed via the receiver’s USB input.
