Here's a press release from Yamaha:
This year the line-up has expanded somewhat and not in the direction most people would expect. We have a brand new model at a brand new price point, the RX-A550. This model sits below the RX-A850 in the AVENTAGE line-up, but doesn’t replace anything else within our AVR range. The RX-A550 includes the latest HDCP, 4k video support, Bluetooth and WiFi on board and features a full Aluminium housing. It also features 5 channel discrete amplification and a specific UK tuning to this model. We’ve spent months focusing on getting this product to sound amazing so for those who want functionality and sound quality in a neat package… look no further!
The rest of the range will be updated to the RX-A850, RX-A1050, RX-A2050 and RX-A3050. Replacing their respective models from last year. All models from RXA850 and above will include HDCP 2.2, Bluetooth and WiFi on board, support for the full 4k colour space of 4:4:4, Dolby Atmos, DTS:X, RS-232 for custom install integration and a new Subwoofer EQ to get the most out of your bass space.
We’ll be using ESS SABRE DACs in the RX-A1050 and above, with the ES9006 being used on the RXA1050, two ES9006 DACs on the RX-A2050 and an ES9016 and ES9006 DAC on the RX-A3050. Combined with these is our new Polymer Multi-layer capacitors, specially developed with Rohm technologies in association with Yamaha. These new capacitors are tiny in size but pack a huge punch when it comes to unrivalled sound quality. You’ll find a much smoother and refined sound from Yamaha’s AV Receivers going forward which is largely thanks to our research and development of these new tiny components. We’ve included a new Jitter clock in AVENTAGE for 2015, specifically focusing on network, Bluetooth and USB playback. As times move on there is a distinct trend towards using network based music sources so we want to focus on making this kind of source as good as it can be. Not only this but there’s a new Volume IC built into the AV receiver range which not allows a smoother control over volume from us as the listener, but dynamic range in music and movies is better controlled as well. Taking a movie soundtrack as an example, often it may go from a big explosion to a quiet scene just afterwards and sometimes this can sound disjointed. Thanks to our new Volume IC unit, it’s not quite as cutting and is a more controlled experience.
We will also support hi-res playback on all the AVENTAGE models, including up to 5.6MHz DSD, 192/24 FLAC/WAV/ALAC/AIFF and MP3 and WMA files. These can be played back over the network or USB as well as using an external player if you so wish. Other improvements include a better refinement of our YPAO auto speaker calibration, a new GUI HD uplift, continuous upgrades to our AV Controller app and some extra adjustments made for zone playback including delay adjustment and a handy main zone sync function. The range of AVENTAGE AV Receivers from Yamaha this year will support the newest object based audio formats, referring specifically to Dolby Atmos and DTS:X. Dolby Atmos will be supported on the RX-A850 and above, while DTS:X will be available on the RX-A1050 and above.
These should be available from approximately August/September. The RX-A550 will be £550, RX-A850 £900, RX-A1050 £1000, RX-A2050 £1500, RX-A3050 £2000.
