One year after the Aventage A40 series, it looks like Yamaha is readying an updated A50 series. According to Heimkino Partner, the new A50 series would comprise of the RX-A750, RX-A850, RX-A1050, RX-A2050, and RX-A3050; and all of them would support 4K/60p 4:4:4 signals and HDCP 2.2. Those following Yamaha’s receiver lineups will remember that HDCP 2.2 is also supported in the new RX-V79 series, with the two highest models, the RX-V679 and V779, supporting 4K/60p with up to 4:4:4 color sub-sampling.

According to the website, the RX-A550 is a 5.1-channel AVR with 80W per channel of rated output power (6 ohms, 0.09% THD, 2ch driven). It has built-in Wi-Fi, Bluetooth, and high-res audio playback support, including DSD 2.8MHz/5.6MHz and FLAC or WAV files at 24-bit/192kHz resolution. Designed with an Anti Resonance Tech Wedge to help reduce vibrations, it also comes with the Yamaha Parametric Acoustic Optimizer (YPAO) for automatic speaker setup.

Moving up a step is the RX-A750, a 7.2-channel receiver with 90W per channel of rated output power (8 ohms, 0.06% THD, 2ch driven). Expectedly, it has all the features that the RX-A550 has (e.g., HDMI 2.0, HDCP 2.2, integrated Wi-Fi and Bluetooth), as well as additional ones like YPAO RSC (Reflected Sound Control) and a Zone 2 mode with intelligent amp assignment for the surround back channels. It also features an improved user interface, a new Burr-Brown DirectPath DAC, a new volume IC, and an independent power supply.

If you want Dolby Atmos, you’ll get it from the RX-A850 onwards. That and more power (100W per channel; 8 ohms, 0.06% THD, 2ch driven) are the main differences between the RX-A850 and the RX-A750. If true, this is certainly great news, as the current RX-A840 doesn't support Atmos.

While specs for the RX-A1050, A2050, and A3050 aren’t revealed, it’s safe to assume that the RX-A1050 is a 7.2-channel AVR, the A2050 a 9.2-channel AVR, and the A3050 a 9.1-channel AVR with 11.2-channel expandability. The two highest-end models are also expected to feature higher grade components, better construction, and even more versatile Zone control (including Zone 4). There's no mention of DTS:X support in the new Aventage A50 series, so it's possible that it'd come in a different series or that Yamaha would issue a firmware update to enable DTS:X on some Aventage models later on.
