Leaving Solid State Equipment on all the Time

Someone told me that: 
  • Leaving your gear on all the time allows all the components to "come up to temperature."  
  • Transistors, resistors and other devices all have specific operating temps that they work best at. Below these temps, they're not performing at peak capability. 
  • Transformers will generally take 2-3 days to settle down and come up to their operating temps. 
  • Capacitors will take anywhere between 3-4 days to settle down. 
  • If you're continuously turning off the gear, you're basically hearing the system as it's first waking up in the morning. After it's been on for a few days, you'll hear that the tonal balance smooths out, that the top end becomes sweeter and purer and that bass has more control, articulation, and becomes more natural. 
Any truth to any of that?

My old BAT VK600SE definitely took a good couple hours to sound its best.
However leaving it on, in Florida, all the time was just not realistic.

My present Ayre ax7e stays on all the time, mytek Brooklyn on all the time,Bluesound vault2 on all the time,Goldnote phono stage on all the time.
Always ready to rock and roll now!

Question for the OP!
I was considering upgrading my vault to the inuos zenith, how do you find it in practicality and ease of use and sq?

Zenith setup is very user friendly. Instead of Roon, I use LMS  because I have several Squeezebox Duets, Raspberry PI Squeezelight players, and AirPlay speakers making up my whole house music system.  

I have the 2 TB model and have started ripping my CD library to it.  There are two modes. In “quick” mode it takes about 8 minutes to rip a CD.  The other mode is slower but you’re suppose to get a better copy.  I use the quick mode and have had no problems.  What I don’t like is sometimes their album art doesn’t match the CD cover.  I don’t think they are using a US based source.  

Zenith’s SQ is much, much better than my McIntosh 7008 CD changer and the Squeezebox Duet that it replaced. Local FLAC and DSD music files sound great, as does Tidal HiDef music.  

I have the MK2, their MK3 version will be out next month.  I got a great deal on a demo MK2 that I couldn’t pass up. When my ship comes in, I’ll upgrade to the Statement model :-)

I have two class A monoblocks I turn off, after a listening session as well as two Aesthetix tubed preamps that remain in standby, when turned off.  It takes approx 30-60 minutes for them to come to operating temp.  As stated above, the temps of all my amps, as well as the operating costs of leaving them on continuously, prohibits my leaving them on.  My Theta Miles, also stays in standby, with the exception of a forecasted electrical storm, then everything gets unplugged, except for one or two components I would like to get zapped😊

I must say, my music does sound much better when I leave the equipment on.  

My NAD M12 pre/dac and M22 v2 power amp have a standby mode, but the Zenith does not.  First chance I get, I'm going to place the NADs in standby mode for a few hours and then power them up to see how long it takes for them to warm up.

I also have class A Mc MC2600 and Pioneer SPEC-4 power amps, which I rarely use these days.  I've always left those puppies off until I plan to use them.
