Leave system on or power everything down?

Hi All,

I know this is a frequent topic. But I'm looking for all of your expert advice on this. My HT system consists of:

Krell Foundation 4K - processor

Earthquake Cinenova Grande 5 channel power amp

DENAFRIPS Ares II 12th - DAC

4 SVS SB4000 subs

The wife and I only use our theater room Friday through Sunday. Monday through Thursday we just hang out in our living room. 

Since the HT system is off 4 days straight, I have recently started to turn all master power switches to off on the Krell, Earthquake, DENAFRIPS, and all 4 subs. The Earthquake only has the 1 power switch unlike other amps which have a "standby".

What do you think, should I leave everything on or in standby or better to power all off? And if standby is the consensus, what about the Earthquake amp? Leave that on or switch off?

Thank you in advance!

Best Regards,

Brian
