The A25 amplifier steps up to a Class G amplifier and the ESS ES9280AQ DAC, along with USB-C inputs, LED illuminated highlights, and a seamless OLED display on the front panel.

The ST5 music streamer supports a wide range of music services, including Amazon Music Unlimited, Qobuz, Internet radio, podcasts, Tidal Connect, and Spotify Connect. It also offers support for MQA, Google Chromecast, Apple Airplay2, and Roon. The CD5 CD player supports CD, CD-R, and CD-RW playback, as well as playback from USB mass storage. Both the ST5 and CD5 feature an ESS ES9018 DAC and boast 24-bit/192-kHz resolution.
