HDMI, 2.2V peak,
10Hz to 22.4 kHz bandwidth
At maximum output level of 2.2V nominal, I was able to get 104.53 dB at 1.448V which increased to 104.98 dB at 1.9V and ultimately finishing at 104.9 dB at 2.3V.
I believe 104 dB was the highest SINAD recorded here by
@amirm with the AVR-X8500H with the original AKM DAC at 1.45V. To be fair, the Denon did that with unbalanced output as compared to the HTP-1 with balanced output.
@amirm, this is a record breaker for a 16-channel processor for highest SINAD at any level using a plain laptop HDMI output (with the laptop even plugged into AC power).
At the relaxed standard of 20Hz to 20 kHz bandwidth, trying to break the 105 dB barrier, I was able to get this:

So again, the HTP-1 has the highest measured performance of any 16-channel processor measured here to date. The Marantz AV10 should have higher SINAD, but no one has sent one in yet.
The HTP-1 is a bargain if you need its features and have an amplifier with sufficient gain.
