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.

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’.

2 additional points;

1-in Roon as far as clearing the 'image cache' once you hit that button you do need to wait for at least 10 seconds before you restart Roon for the action to complete.

2-i use an Equi=tech 10WQ 10kva Isolation Transformer for my whole system. in the Pacific Northwest where i live we very rarely get electric storms, maybe once every 3-4 years. nothing like the mid west or southeast. but when we do i just throw the main breaker for my whole system and it's is isolated from the grid and protected. even when connected that transformer protects the system from spikes.
