When input is received, you see the green bars on one of the valves on the monoblocks - the bar appears from top and bottom at the same instance even-though volume was zero. This shows input was present.

How do they sound?
Overall a pretty nice sounding unit. The HF was natural and fluid. Mid was very natural and well defined. Bass could be better but lack authority.
Beautiful set for vocals.
And grunty enough to drive my DIY LS 3/5A with the DIY AB1 connected in-series, without braking a sweat!!!
