It is a "streaming amplifier" that comes with the NAD sister Bluesound's "BluOS" streaming module as standard. The module enables access to music from the home network or online streaming services via LAN or WLAN. The M 33 can also be integrated into multi-room systems, and it can receive music via Airplay 2 or from Roon servers using the RAAT protocol. It can both receive and transmit via Bluetooth using the aptX HD codec. Various S/PDIF, AES/EBU, HDMI, Phono-MM and line inputs in Cinch and XLR complete the feature list. A special highlight is the integrated "Dirac Live" room correction including a measuring microphone. Two slots for MDC modules are provided for future expansions. As continuous power, 2x200 Watt at 4 and 8 Ohm are listed in the data sheet. The M 33 is scheduled for April 2020 – at an estimated price of 5500 Euro.
