Seing the specs of these reminds me of the good ol' 90's where this was a 2000 W system.

I hear you. But in this case the Aiyima A07 Max has similar specs in mono mode...

Like most sellers similar amps they're giving the datasheet power output for the TPA3255 without mentioning that it's at 10% THD+N with a different PSU to the recommended one, often with better heatsinking than they provide. HiFi manufacturers quote power output at lower distortion levels, often 0.1%, which would be much lower. Note the difference between the A07 Max claimed and measured power output - 75W into 4R rather than 300W.
