Those looking to still use their library of compact discs can easily buy a simple player. For those looking to use their CDs while taking advantage of more modern audio sources, Marantz has built the CD 50n. Its built-in WiFi with HEOS supports streaming sources like Airplay 2, Spotify Connect, Tidal, and TuneIn Radio, while an HDMI ARC port enables TV signals to take advantage of the unit's technologies. Those include custom digital to analog filters, a built-in digital pre-amp that allows it to be hooked directly to powered speakers, and support for hi-res audio formats up to PCM 384 kHz/32 bit and DSD 128. The sculpted surface of the front plate provides visual interest and an elegant backdrop for the large OLED screen.
