Not all BEl Cantos may work equally well with the tube pre-amp. A bad match here might account for what was heard.
Also, I believe power supply implementations are different in different BC models and could make a difference.
I can say for certain that the BC ref1000m's in my system do not match Weseixas' description.
Never heard the Threshold so cannot compare to that. I'm sure it is a fine amp in of itself as well from what I do know.
Different amps do sound different, even under optimal circumstances, so not all will take to any in particular the same even if everything is set up to integrate perfectly.
