I purchased this receiver the last time it was posted on here at roughly the same price and I am delighted with it. This was a couple of months ago and the deal went cold strangely but I'm hoping this time around it might get the heat that I think it deserves!!

I haven't seen the price of this AV drop below £547 here in the UK so this is a saving of almost £180... and you get a lot of receiver for that money:

The Onkyo TXNR646 receiver combines high-quality 7.2 channel amplification with 4K UltraHD HDMI inputs and built-in AirPlay, Wi-Fi, Bluetooth streaming, Spotify Connect, and more for an incredible surround sound experience.

Engineered for Dolby Atmos sound
Optimised for Dolby Atmos, you can be amongst the first to experience the wonder of Dolby Atmos in your own home. Producing a multi-dimensional and totally immersive sound, Dolby Atmos has been hailed as the greatest advance in surround sound for 20 years - so don't miss out!

A powerful performer
Making sure you feel the full impact of DTS:X and Atmos, the Onkyo TX-NR646 boasts a powerful 100w per channel amplifier . The high current design with WRAT (Wide Range Amplifier Technology) and discrete circuitry easily sustains powerful but testing dynamics such as explosions and intense action scenes.

High Resolution sound
As well as offering multi-dimensional surround sound, the Onkyo TXNR646 is compatible with High-Resolution Audio. This gives the highest sound quality, that's far more natural sounding than standard audio. The premium 384kHz/32-bit DAC is compatible with a wide range of HD audio formats, including DSD 5.6 MHz and FLAC 192kHz-24-bit for exceptional sound quality.

Wi-Fi with Spotify and AirPlay
Connect via Ethernet or wi-fi to your home network and gain access to a whole new world of entertainment. From here you'll be able to access a massive range of Internet radio stations plus music services such as the hugely popular Spotify and Deezer. New to this year's model is the introduction of AirPlay, making it easier than ever to stream from your Apple iOS devices, too.

Stream music from your mobile with Bluetooth
With a Bluetooth receiver built in, it's easy to enjoy your music from other devices. Pair with your smartphone, tablet, laptop or PC and wirelessly stream all your favourite music. With the possibility of streaming music services, such as Spotify, Deezer and Tidal, as well as your own music library, you get access to near unlimited music! Advanced Music Optimiser improves the dynamic response from compressed music sources, adding 'sparkle' to the sound and restoring the sound quality.

The latest connections
As you'd expect from this leading AV brand, the TXNR646 comes with the latest connectivity. The TXNR646 features the latest HDMI 2.0a connections and supports HDCP 2.2, which means you can stream UltraHD video and that it's ready for the next generation of 4K discs. With twin HDMI outputs you can also have a second AV display in another room.
