Leave it on?

leave on---Wadax dac, server, power supply, two Ethernet switches, class d bass amps, Herzan TS active isolation, Esoteric clock.

if gone for over a week these are turned all the way off.

standby--darTZeel amps, battery powered preamp

off; tape decks, tape tubed preamps, phono tubed pre, turntables, power supply for field coil cartridge and field coil arm.

I have a field  coil power supply for my speakers. I do keep it turned off. 

For those of you that leave your gear on like dacs, streamers and SS amps I have a tip to try.   Every couple of weeks or so shut them down for 5-10 minutes and then restart. While I don’t understand why, I can say it did something positive to sound quality. A couple of designers I respect told me about this.  

music management software, servers, dacs, and network switches need to be re-booted often to clear stored data cashes that will build up and cause issues. all the meta data gums things up. Roon has a ’clear cashe’ button that helps under ’setup’.

Very true. Amplifiers also benefit sonically in my experience.  

After trying the always on or turned off ways multiple times, I have adopted the following method:

Turning off every piece of equipment that has an on and off feature in front of the unit and always leaving on the ones that only have a on and off function on the back of the unit. I am not gonna try to outsmart the designers any longer. It's common sense to me.
