Is the TX-RZ50 worth it over the TX-NR7100?

The RZ50 adds THX certification, more power and a heavier chassis over the NR7100. If you drive large speakers or want reference-level volume, the RZ50 is the better pick.

How many speakers can it power?

It amplifies 9 channels and processes 11, so a 5.2.4 or 7.2.2 Atmos layout works without extra amps. A 7.2.4 setup needs an external amplifier for the last two channels.

Does it support 4K/120Hz and 8K?

Yes. Its HDMI 2.1 inputs pass 8K and 4K at 120Hz, which suits PS5 and Xbox Series X. Check that your TV and cables also support those modes.

Does it have Dirac Live?

Yes, Dirac Live room correction is included. You run it with a PC or Mac and a microphone, and it takes longer than a basic auto-calibration.

The receiver, a calibration microphone, a remote, batteries and a power cord. Speaker wire and HDMI cables are not included.

AV receivers usually drop during Black Friday, holiday sales and when a new model is announced. Track its price history and buy when it falls below its recent average.
