AVR power ratings are misleading by design. The Denon X3800H's 105W/ch becomes 68-80W all-channels-driven. Here's how to read the real specs: impedance matching, ACD power, HDMI bandwidth, channel count for Atmos, and room correction.
Denon X1800H for most 5.1 setups, Yamaha RX-A4A if you want YPAO RSC, Marantz Cinema 50 for premium builds. How many channels you need, why room correction matters more than watts, and 2026 picks at every price.
A 100W-rated Denon delivers about 65W with all channels driven. The ACD formula, how impedance affects real output, and a calculator to check if your receiver has enough power for your speakers.
