Power on or off LINN IKEMI

Is it ok to leave the power on at all time on the Linn Ikemi, or should I turn it off when is not in use.
I turn mine off everytime I turn the system off. I see no reason to leave it on. I really don't believ there are enough electronics in the Ikemi that would benefit from being kept warm.
I leave mine powered up all the time.
I had my ikemi for 2 years,before up grading and never turned if off.
