The only amplifier that combines HDMI in/out ports and 2.1 channels on the market right now.

I won't go into details about its sound quality, as the most important criterion for me was the abundance of features and connections it provides.

It supports up to AirPlay 2 (through the latest software update) and its other capabilities and conveniences cover everything a modern receiver can have at the moment.

It accepts and transfers (tested) 4K (3840x2160) 60HZ YCbCr444 12-bit video without any issues (as long as the appropriate source, TV, and HDMI 48Gbps cables that support this transmission are used).

The only negative aspect I will mention is a mechanical sound - click - that is heard at irregular intervals 2-3 times during a day, and the same sound is also produced by the TX-8250 model. Look for discussions about this phenomenon on foreign forums, as it seems to exist in other models of the company as well.

Overall, if you are looking for a 2.1 channel + subwoofer amplifier with HDMI, the choice of the Onkyo TX-8270 is a one-way street and will fully satisfy you.
