I'm on the page that science is science. It's just the test/measurement protocol.
I did look at the compilation of their 1W SNR.
SNR @ 1W
Benchmark AHB2 = 96 dB (Stereophile's measurements)
Parasound JC1+ = 87 dB (Stereophile's Measurement)
I don't know where all those were from and the test conditions, but the comparison between the JC1+ and AHB2 would seem valid if both were measured by Stereophile as long as both were for the unweighted condition (not stated), and @ 1W (that you stated).
The AHB2 and Parasound JC1+ 1 watt SINAD posted Stereophile measurements are not correct.
The load also matters, so using the 1 watt measurements (2.83 volts into 8 Ohms) the distortion values and SINAD are:

https://www.stereophile.com/content/parasound-halo-jc-1-monoblock-power-amplifier-measurements-0
AHB2 1 watt 8 Ohms: 0.003 or SINAD 113
Parasound JC1+ 1 watt 9 Ohms: 0.012 or SINAD 78
AHB2 Stereo mode into 8 Ohms (clipping 108W):
AHB2 Bridged Mode into 8 Ohms (clipping 410W):
JC1+ into 8 Ohms (clipping 450W):
The Parasound has about 2x the power (or 3dB) more power than the AHB2 bridged into 4 Ohms.
