Halo JC1 lacks on-off breaker on rear panel


Question to Mr Crump - is it OK to turn the JC1 on/off daily, depending on listen or not listen? Does such a way of using could be harmful in any way for JC1�s status (in terms of, say, durability or stability of certain parts/circuits)? You Mr Crump keep your own JC1s �on� all the time. What is the purpose? Shortened warm-up period only, or maybe something else - for instance, preserving durability of inner circuits via avoiding so-called �cold start� occurence too frequently?

Stand-by option not being provided with JC1, unlike many similar big powerful amps such as Krell, Pass or many others, which are supplied with power-on breakers on rear panel (JC1 has not such breaker), supposed to be switched �on� all the time, except in cases of longer inactivity. Does it mean that JC1 is somehow �more resistant� to neccessity being �stand-by� while not �on�, compared to other heavyweights?

Generally speaking, what�s the reason for keeping power amps �stand by� while not �on�? Most manufacturers strogly recommend that in owner manuals (mentioned Krell and Pass Labs). Of course, we all know stand-by position keeps circuits ready for quick turning into amp�s full potential, shorting warming-up to only half an hour or so. But, I would consider that like minor benefit, IMHO.

My major dilema is, actually, does �stand-up� instead �off� contributes longevity/stability/lifespan of amplifier? Vice versa - does �off� after �on� affects negatively some of amplifier�s parts/circuits??? Highly appreciate comments, due to frequent power failurs in my place.

I would leave them on all the time but switch them to low bias (toggle on rear panel) when not listening. They just get warm, not hot, in low bias.
