Turn off or leave on?

I am curious to know what others are doing with respect to powering on/off their hifi systems. My system like most is a mix of tube and SS components: tube gear (mono amps, preamp, and phono). SS gear consists of (SACD/CD player, DAC, server, and external clock) and I have a conventional DC powered motor for my LP player.  On days when I know I will listen to music, I turn it all on and leave it on until I go to bed at which time I turn it all off. I have read that it is better to leave SS components on (limit the number of temperature swings associated with powering up) and only power down tube gear (extend tube life).  Many of the components have power saving features so they shutdown after an inactive period but that is more of a sleep mode as I understand it and not the same as a true power down.  Not to complicate the question further, all the amps are hybrid so they have in effect both tubes and transistors  My SS gear is a dCS Vivaldi One plus external Vivaldi clock, server is Taiko Extreme, and my amps are all from Tenor Audio. LP player is AMG 12 that uses a typical external DC motor always left on and powered up.

Everything off when not using, especially when not listening for an extended period of time, due to work etc..in fact, I shut down all power conditioners and even shut off the breaker. The only detriment is a long Warm up period, especially with my tube gear and class A Amp. It will usually take up to 90 minutes for it to sound its best. With the supposed shortage of tubes, probably a good thing to shut down. I would not know of the shortage, as I’m set for tubes, as I bought them years ago, mostly just small preamp type tubes.

I leave my DAC on almost all the time, but it's power consumption is minimal unless playing high resolution music.  My SS integrated is AB and I leave it on a lot because I rarely get to sit and just listen for an extended period of time, but it does really well even when first powered on.

OTOH, I have some Class D amplifiers that do really poorly for music until powered on for 3-4 days.  They are very cool running though, with minimal power consumption when not playing music.

Your mileage may vary. :)

I do want to point out we are not always aware of or home when power surges hit. I'm obsessive over surge protection in this home but if I know a storm is coming over night I still turn everything off I can, including the surge protectors.

  As I have a tube pre and power amp, I turn them off unless I’ll be listening again in the next 6-12 hours. My Schiit Yiggy stays on 24/7, and my Richard Gray does not turn off. Class D amps are another item that takes a long time to warm up.

My system is tube phono pre-amp, pre-amp and power amp (TT, dac, cd and streamer are SS), definitely, always completely OFF, unless listening. I use a 1 hour warm up prior to a session (average 6 out of 7 days / week).

My system is SS up front that goes into standby each night. The tubed phono stage gets turned on once a day if I’m listening and turned off at night. The rest of the gizmos stay on.
