The RX-V671’s headline feature is its DLNA-certified networking functionality, allowing you to stream music from a variety of sources including vTuner internet radio, Napster and PCs on your home network.
For the latter, supported files include MP3, WMA, AAC, WAV and FLAC, which should cover most people’s digital libraries. Sadly there’s no AirPlay support, but the optional YID-W10 wireless iPod/iPhone system does virtually the same job. Apple devices and memory sticks can also be connected to the front mounted USB port.
As an added bonus you can control the RX-V671 with a smartphone over your network with Yamaha’s AV Controller app. All of these network functions rely on the Ethernet connection as there’s no Wi-Fi support.
And as per usual Yamaha has gone overboard on the DSP modes – its CINEMA DSP 3D offers no less that 17 programs, all lending different characteristics to suit various movie and music genres, with overly specific names like ‘Concert Hall in Berlin’. Other tech, like Dialogue Lift, Virtual Cinema and Compressed Music Enhancer helps you get the best out of whatever you’re listening to.
The RX-V671 also supports an extra pair of ‘Presence’ speakers, which need to be connected to the dedicated springclips on the back and positioned outside the front speakers about 1.8m from the floor. Using the on-board DSP processing, these speakers supplement the sound from the front speakers with extra ambient effects. Additionally the Virtual Presence Speaker mode aims to achieve the same effect without using extra speakers.
If you’d rather enjoy soundtracks straight-up you can bypass these modes. And as you’d expect the Yamaha is fully equipped to handle Blu-ray audio formats like Dolby True HD and DTS HD Master Audio, while its output power is rated at 7 x 90W.
Any video sources you have running through the RX-V671 can be upscaled to 1080p, plus the video processors offers motion adaptive/edge adaptive deinterlacing and 3-2 pulldown detection where required.
