Brooklyn Bridge is identical to Brooklyn DAC+ in terms of audio circuits and performance but has the addition of a built-in Network Streamer. AES/EBU digital input is replaced with an ethernet network connector, a WiFi antena and a USB port for external music hard drive. Just add a tablet (ipad or android) for complete music system to stream Tidal MQA, Qobuz Hi-Res or other streaming services or play local files connected to Brooklyn Bridge USB port. Roon requires additional Roon Core. Like in the Brooklyn DAC+ there is line and phono analog preamplifier and a reference headphone amplifier.
