The new slimmer networked AV receivers are designed for home cinema enthusiasts with limited space
The Marantz AV receivers are more networked with endless sources of music content: AirPlay technology lets you can listen to music library of iPhone, iPod touch and iPad wirelessly, thousands of Internet Radio stations, Spotify and Last.fm, DLNA to stream music from a network attached storage device.
Following the footsteps of their predecessors, the new NR1604 and NR1504 promise pack a mighty punch on sound. The NR1504 has a 5-channel amplifier with 100W equal power per channel, while the NR1604 7-channel amplifier with 100W per channel.
The main difference between the two is analogue and HDMI upscaling to 4K/1080p (Full HD) on the pricier model NR1604, and it supports newer 4K Ultra Hi Def TVs.
The receivers also has a slew of HDMI ports to hook up other devices like tablets, DVD player, phones, USB port, and supports audio formats like Apple lossless, WAV HD and FLAC HD 192/24.
