Vandersteen Quatro CT

+1 rcprince    The only time I turn off my SS amps is when I'm changing gear in the system or doing semi-annual connector cleaning.  Some may argue that SS amps should be left on all the time to promote thermal stability.  The side benefit is that the sound is always first rate.

i have the VX-R Twenty and leave it on most of the time ( vs standby ) Thrre is a difference in SQ even tho it is smaller than the pre twenty change in SQ from standby to fully warmed up. I attribute this to the old topology and thermal trac devices. The double diamond changes seem to also benefit in SQ changes from standby - even so while the twenty sounds excellent about 20 minutes in I leave it on most all the time.
cant comment to much about Twenty break in time and changes as I got my 7 at about same time.
have fun !!
that is what this is all about !!!
joy

I have a Pass XA-30.5.  No way I'm leaving that beast on all the time!  But it warms up pretty fast.

giving the Clark Terry a listen - yes a very fine recording on many levels :-) 

Karl you would be using 200 W
not sure what the vxr is drawing when on at idle but it is 45 W in standby.
