Power tubes worm up to its normal offset within 10min Preamp or driving tubes worm up within less so no need to wait for half-hour before listening.
How your player 'drives nuts' your DAC you didn't provide details. Is thump or click heard from your speakers??
Your player shuts down I believe to stand by mode. the only way is to keep it playing on repeat mode if there such with muted rest of components when you don't wish to listen.
I didn't get what Decay said and what components are tube or not and what components are on or off 365/24... One lucky won't ever mean someone else's luck. Tubes tend to blow and take away other circuit components including setting some fireworks and smokes. ALWAYS TURN OFF TUBE ELECTRONICS WHEN YOU'RE NOT HOME OR SLEEPING!!! Becides, do some arithmetics and multiply years*days*hours*kwh used*$ then subtract the presumed number of listened hours(you may add some worm up time) to get an idea how much money Decay already waisted.
All of Dekay's small signal tube components may draw upto 100W of total power so one may or maynot notice the waste of money indeed.
I also keep our Sharp mini system powered up 7/24/365 as it takes 3-4 days (from a cold start) to sound half way normal (a week plus is more like it).
Does that mean that within a week it gets to desired temperature and a day before the temperature is obviously lower?
