How can these all be wrong? Here is a "•100 watts x 7 (per channel, 8 ohms, 1% THD)"" Sony clipping at about 75:
Sony STR-DG910 A/V Receiver [2007]
STEREO PERFORMANCE, DIGITAL INPUT
Reference level is -20 dBFS; all level trims at zero. Volume setting for reference level was 60.
Output at clipping (1 kHz, 8/4 ohms, both channels driven): 75/109 watts (18.8/20.4 dBW)Distortion at reference level: 0.05%
Linearity error (at -90 dBFS): 1 dB
Noise level (A-weighted): -74.5 dB
with 96-kHz/24-bit signals: -78.8 dB
Excess noise (with/without sine tone)
16-bit (EN16): 0.25/0.35 dB
quasi-20-bit (EN20): 14.7/14.8 dB
Noise modulation: 0.6 dB
Frequency response: 20 Hz to 20 kHz +0, -0.1 dB
