Leave it on?

No on and off switch anywhere, the designer obviously meant for the unit to be powered on 24/7.

Everything but the amplifier stays in 24/7, the amp usually gets turned off before I go to bed.  Everything gets unplugged when bad weather is approaching.  All of my equipment is solid state.

What if your amps don’t even have an on/off switch, just an IEC?!  I just leave them powered up all the time.  SMc Audio now uses thermal-magnetic switches (think Swiss Digital Fuse Box) that serves the purposes of both equipment protection (i.e., fuse) and on/off switch.  After sourcing two of them from SMc, I mounted them in-line, in the wall, one for each amp and replaced the line fuses in both amps with copper rod.  At least I can now turn the amps on/off without unplugging them.

@mitch2 Nice. I’m jealous of your magnetic switches.  My upgraded DNA 0.5 has the power switch disconnected so I’ve gotta unplug my amp to turn it off.  But I leave it on all the time anyway, unless I’m going away for at least a few days, so it’s no biggie but still it’d be nice to have the power switch working.  BTW, Patrick at SMcAudio said I probably prolonged the life of my amp by years by leaving it on.   All I know is the thing lasted 30 years with me leaving it on.

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.

I turn everything off the second I stop listening. And thanks guys for using this an opportunity to lecture us on climate change. 

Again lets talk about nuclear and not the other other underperforming solutions.
