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

Send an email to the manufacturer and ask their opinion.  I run Hegel equipment with soft start circuitry.  Hegel recommends turning the eqipment off when not in use.  I've left it all powered on 24/7 for a week and it just heats the room up.  Since you know when you will be using the system,  just power it up a couple hours beforehand.   SS eqipment requires very little time to reach peak performance.  I know many believe always on is best, I'm just not in that camp.  But they may be right.   Do what makes you sleep easy at night.  Cheers.

Thanks for the replies. I actually did reach out on the Grande and he said leave it on, but then changed and said turn it off when not in use “doesn’t really matter’. I can reach out to Krell and SVS as they’ve both always been very responsive. Same with DENAFRIPS. Was just hoping to get a consensus here rather than making 4 calls-LOL!

 

Always appreciate everyone’s help, time, and support!

 

Thank you!

Turn it OFF. Makes no difference to sound. Warm up 30 minutes before listening.

It is enviromentally irresponsible to leave it on................. meaning Period!

It's environmentally irresponsible to even own audio equipment. Sing to yourself.

I hold a traditional belief that electronic components are subject to wear and tear, potentially shortening their lifespan if left turned on continuously. However, frequent power cycling can also stress certain components like relays. My first integrated amp, Harmon Kardon avr25 ii, has served me well for 28 years and still performs admirably. However, the relay may need replacement in the future to eliminate the minor, yet annoying, pop noise it produces when initially powered on.

While I don’t believe this pop noise will harm anything, I’ve adopted a temporary solution to avoid it. I disconnect the negative terminals on both speakers and reconnect them after the amp is powered on.

I would recommend leaving the system on if you use it periodically throughout the day but consider turning it off when you’re done for the day.
