Headphone Output: Yamaha AVR

Yamaha RX-V667

Slightly outdated but still fully functioning AVR that I got my hands on. Measurements only cover the headphone jack. Connected via HDMI, 2 channel PCM mode.

Comment

Looks good for me. The “pure direct” mode is supposed to turn off anything not related to the sound like video processing, and it seems to have a measurable effect on the noise floor. With enhancers and DSP modes and so on, you get a fair bit of stuff in the spectrum, but that’s to be expected. Remaining noise is likely created at least partly by the test setup.
