Hello,
I have a number of Cube amps recently purchased and like to ask, do owners keep their's powered up 24/7 ?
If so what are the benefits you may have discovered ?
I ask this because I am first time Bryston owner and coming from Class D amps.
Thank You.

My 14-squared needs about 30-60 mins. warmup, to sound really good. Not 24/7. It eats about 150W just idle. So my answer is no. But I am not familiar with the cubed amps' energy characteristics.

I found no sonic reason to leave with my B135 SST2 or cubed on when I'm not listening, and I can't say I notice differences in quality between, say the first 5 minutes and 30 minutes in.

I learned, long ago, that turning solid-state electronics off-and-on tended to shorten life expectancy. So, I keep my  BCD-3, BP17c and 4Bc on continuously.
I worried about the electric costs, as I have an all-electric house; however, it averages out to about $3  to $5 per month.  Cheap insurance.

Depending on your $ per kilowatt hour, YMMV.

  Once fully broken in. No. It builds up magnetism. After turn on in an hour when up to operating temp. ready for prime time.

I have  let my Bryston audio equipment in 24/7/365 for 10 years straight. (with the moments off for power cord swaps, moving stuff around...)
When I acquired my Bryston 4B-SST² I noted that it took a few hours to sound better, and a full day to sound it's best.
Whether this applies to the cubed I do not know. One thing I read is the Cubed amplifiers at idle use about half the electricity the squared models did.

Normally people like to power on upstream components before the amplifier; then turn off the amplifier before turning off upstream components. If you have a tubed preamp/DAC etc, you would not want to leave them on 24/7 How do you handle the amplifier last on - first off in this case?

Your electric bill will explode:

  power corps love this stuff on ,,,,,,  and helps to heat up Canada too.  Yes, leave it on man.  It snowed two weeks ago.

If the amps are solid state, i say just leave them on. Most electrical equipment are more stressed at switch on.
I leave everything switched on all the time, yes my bill is higher but the system is always ready to go. I use my system everyday anyway.

I moved last year, just had a look at my mains regenerator and it shows that the system has been on for 341 days 21 hours and 23 minutes.
So i say leave them on and enjoy.

Stockpile spare tubes like toilet paper.

I will clarify that I keep it in "Standby" when not in use and I do not unplug it from the wall.

Did you mean the hard on/off switch in the back or the Standby/On mode switch on the front when referring to powered up? I assume the later and not the former.

Agreed. I don't think modern transistors require one to leave them on all the time. A 30 to 60 minutes warmup should have them at their peak performance.  I have a Bryston square and a Pass Lab, and Nelson Pass only recommends 30 to 60 minutes warmup for his Class A amps. But, if you have stock in the local electric company, leave the amp on all the time.

I've found with the SST2 and Cubed amps, a 30 minute warmup is fine.  Leaving them up 24x7 is a waste of money.  Regarding turn on stress....it's a Bryston so it's built like a tank....no worries.

One point not mentioned is how often and how many hrs/day you listen?
I listen to my stereo from 7AM entire day to 9 PM. every day..
Waste of time ti turn it off.
You may listen on Saturday for three hours a week. total waste of time to leave turned on 24.7
