Stand-by on Mark Levinson products


My system: ML 331 power amp, ML 32 preamp, ML 31.5
CD transport, ML 36S D/A converter. I can only listen to
music during week-ends and I was wondering if it's better
to leave the system in stand-by all the time. Only the 36S
hasn't a main switch and when connected to the electric outlet it
can only be in two modes: "on" or "stand-by" (blinking led).
31.5, 32 and 331 (in the european version) have a main switch
so they can be switched off even if they are plugged to the
electric outlets. Is it true that take off the power
completely when the system is not in use shortens the life
of the components? I know that the system performs better
when is warm and I put it in stand-by mode few hours
before the listening session. I think that leave the system
in stand-by for 4/5 days (being sure that I won't listen
to it) can wear off my components more than put them in
stand-by few hours before the use.
Am I wrong?

Thanks a lot in advance.

From an engineering standpoint, I would turn the system off during the week. This will be a good tradeoff between thermal cycling and thermal fatigue, thereby maximizing the life expectancy of your gear. Arthur
I have an all-Levinson + Wadia system. I leave all the front-end stuff on 24/7 (except for thunderstorm season) and turn the amp off every night. Never any problems. But if you really don't use it 5 out of 7 days, I kind of agree w/ Aball. Just shut it down.
I have all levinson 433 432 326 390 and others and leave everything in "standby" mode 24/7 too :)
Doggy, if your components have the "standby" mode, you can leave it on all the time (except during thunderstorms). Even my Levinson stuff (which doesn't have standby mode) is meant to be on all the time because they don't have power switches -- except for the amp, which as I said , i turn off at night. But if your amp has a standby mode, I'd leave it on.
