Solid state preamp warm up time?

A local retailer told me this AFTER he has sold me a Solid State preamp - "about twice the time needed for a tube amp, try 4 hours". Bugger.

I have owned solid state and hybrid preamps that take 3 days to sound their best. I would leave the preamp on 24/7 and turn off the amp.

i leave all my SS gear on 24/7 unless i know i wont be listening for a few days

I'm with Mrkoven, if your amp has a standby mode, then just leave it on standby and your amp will be up to optimum operating conditions within an hour, otherwise leave it on 24/7 if you're using your amp most days..
