Leave it on?

I have checked up on my equipment.

Grimm says to leave the MU1/2 on and currant draw is scant.  

Weiss DAC501 consumes 2.2 VA in standby. Some think a twenty hour warm up is key. In use DAC uses 25 VA. 

AudioQuest Niagara Says leave on or off.  I keep on as streamer is connected as are low voltage PSU’s for swich and filters.   

Tubes on for use only  

The internet AI reports it Depends on priority. Best sound = keep it on (except Holliday’s or if you listen very rarely of course), Best for your wallet = switch it off. Always turn your equipment off if you are not going to be using it for a few hours (that’s not great advice) and always turn it off of you are leaving the house or over night.

Yes , for me, if away it all gets turned off  Not good if you need yr. roon core and are using remote?????

I suspect/know darn well that other things in my house suck way more juice than standby audio gear. Internet is connected to so many things and they all are on and drawing power. Kill your television. 

Given switches location on Subs turning off very unpractical. 

Plinius said leave my Class AB integrated on all the time. Their newer ones have the power switch on the back panel. My phono stage doesn't even have a power switch (Sutherland Insight LPS) - if it's plugged in, it's on(unless your power conditioner if unplugged or off).

I know it's socially acceptable to not really care about the planet anymore, but you should turn it off.

We all know that coal is now the cleanest Energy producer that's available, but still good idea to turn off your equipment.  Most ss equipment is durable enough to last a lifetime.
