Leave preamp on all day, off at night


Finally had the funds purchased my first tube hifi component, an arc ref 3. Very happy with purchase so far but has raised a concern. System is in main living room - wife and kids listen casually through day - non critical listening. I listen (more critically) for 1-2h at night when they are asleep.
Im used to solid state components that stay on all day long.
Question- is it a problem leaving the valve pre on most of the day, on most days of the week? Is it really just a matter of burning through the tubes faster,  or are there other expensive delicate components in there that don't like being left on all day? Thanks in advance

Thanks guys, appreciate your response. What you both say makes perfect sense, and is what I suspected. Will do, cheers, divesh 
i would really like to preserve the life of the ref3, and not waste it on background music and TV etc.
My other pre amp is a quad 99, but it doesn't have any HT bypass.
In regards to using a HT bypass, im assuming the connections would be:
source > DAC > HT bybass Pre amp > RCA out to power amp (ARC ds450) and also XLR to ref3 then out to power amp. does this mean i will have two inputs connected into power amp, one from each pre?
