This is a robust amp, solid connections! little breath, notched knobs accurate and useful! the light indicating the peaks are relevant and the system emergency control is effective even if I have almost never triggered since the acquisition of equipment in 1996.
The sound is very dry (or as hard as you prefer).
The heater is very reasonable and this is probably due to the high level of ventilation!
So that a half hours (large max) after the end of a performance, the receiver is portable without fear.
Yamaha hardware, for fans like me!
