I have been wondering what leaving my Rega Brio-R on all the time is costing me so I bought a meter like this:

http://www.amazon.co.uk/gp/product/B000Q7PJGW/ref=oh_details_o01_s00_i00...

 

It's running at 17 watts with nothing going through it and the volume turned down.

At reasonable to loud listening levels through my B&Ws it's using about 18 to 22 watts.

 

Not the time of day to turn it right up Smile Neighbours may complain.

 

So yeah, it costs Smile

RE: The cost of leaving your amp on

The website for the Rega brio R says:

Power consumption:

195Watts at 230/115V into the rated load of 8Ω .

Is this at full power?

RE: The cost of leaving your amp on

Nowhere near full load - as stated - reasonable listening levels.

Around or less than 9pm on the volume control.

RE: The cost of leaving your amp on

I turn my Brio R on about 9am in morning then I turn it off before bed!

The power used is neglible!

Off topic - another forumite with a Rega system...... Brio R/DAC/RP3 - cant beat it!

RE: The cost of leaving your amp on

I live mine 24/7 ON, with the volume knob to 0 . 

And yes I did note differences on living it on 24/7!

RE: The cost of leaving your amp on

I tried it with mine a few years ago and I did find that the sound did improve noticeably after the amp and power supplies had been on for a couple of days. But I was more of an anal hi fi guy back then. Now i'm more chilled about it and I can't be bothered with leaving everything on. The hifi gets switched on when I need it and switched straight back off when i'm done.

What is the fire risk from leaving amps on all the time, I certainly would leave an amp on if I was not there or overnight.

Does that metre affect the sound quality?

 

How hot does the Brio get?

RE: The cost of leaving your amp on

Strange one this.......

When I am driving my Brio R hard it seems barely warm, however when its been standing idle it is warmer.

I also notice it is warmer after using Input 1 (Phono Stage) than the other inputs.

Just an observation!

RE: The cost of leaving your amp on

I wasn't paying attention to the sound quality with the meter — but I would expect nothing at all.

The Brio-R stays at about 35 degrees c most of the time even when not playing anything — a little warmer when it's playing very loud.

The meter shows that its not really pulling any extra power when playing so I wouldn't expect it to get a lot warmer than when it's idle.

RE: The cost of leaving your amp on

I just read Alan Shaw of Harbeth comments on this subject. He generally says leaving the amp. all the time is a waste of time, can reduce its life and is a fire risk.

 

Another hifi myth?

Now you mention it — I seem to remember thinking it was cooler when running once.

I made a mistake of playing a quiet source (laptop turned down) which meant that the volume knob was artificially turned up — this got the unit very warm.

I've had an IR thermometer sitting next to it ever since and check it occasionally.

Hotter when running the phono stage makes sense as its doing more work?
