Leave system on or power everything down?

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.

I turn off all my equipment when I am not using it. I remember the phase, "I don't work for the electric company".

@kingbr Was just hoping to get a consensus here rather than making 4 calls.  Consensus?  This is Audiogon 🤣  Last thought.  We are talking about turning your equipment on/off once per day, not many times.  In that case, heat will do more dsmsge to you equipment over time when its lust left on.  IMHO
