Actual audio question
Is audio still on topic here?
I'm wondering about energy efficiency in regards to components, especially amplification. I have a Class A/B transistor amplifier (At least, I think it is. It's an Audio Research D200.) and since it's hooked up to my computer, I just leave it on most of the time. I only turn off my PC and this amp when I plan to be away from it for more than a day, which isn't very often. So, seems to me like it's probably slurping up massive amounts of power. Even when it's doing nothing, I can put my hand on the beefy heatsink fins and they're quite warm. I've gone through the trouble of making an extra energy efficient PC that only draws about 45W or so when idle, but I suspect my amp is negating any real benefit, and no doubt making my electricity bill much higher. I know there's another class of amplifiers that are much more energy efficient (class D ones perhaps?), and would like some options. Obviously, sound quality won't be as great, but I can live with that. Any recommendations on specific amps (integrated or not) to look into? The main consideration is that it does need to be powerful enough to drive my Spendor s6e speakers, and preferably is within a price range that if I wanted to get one, I could sell my current amp (and maybe preamp) to pay for at least most of it. Thanks for any help. |

The D200 consumes a little over 100 Watts at idle. Unless you play it quite loud, then you can just assume that it is consuming around 1kWhr/day. Dunno what the tarif is in your locale, but where I am that amounts to around US$0.07c per day. So, though I don't like to see needles waste of electricity, I doubt that your amp is a major contributor to your power bill. Heaters, air-conditioners, pool filters, electric stoves and ovens and, most particularly, plasma TV sets are far worse culprits. I know there's another class of amplifiers that are much more energy efficient (class D ones perhaps?), and would like some options. Obviously, sound quality won't be as great, but I can live with that. Any recommendations on specific amps (integrated or not) to look into?

Figure on less than 20 Watts for a typical example, which uses a switch mode (SWPS) power supply. For those that use linear power supplies, the figure will be almost as high as your D200. Probably nearer 50 - 70 Watts, depending on design. Thanks for any help. **You're welcome. -- Trevor Wilson www.rageaudio.com.au |

I've gone through the trouble of making an extra energy efficient PC that only draws about 45W or so when idle, but I suspect my amp is negating any real benefit, and no doubt making my electricity bill much higher. Good call. The easiest move would be to learn how to operate the power switch on the D200 more often. ;-) I know there's another class of amplifiers that are much more energy efficient (class D ones perhaps?), and would like some options. The D200 being high end probably runs hot because the bias current flowing through the output stage is exceptionally high. Just picking a more humble amp (that probably sounds just as good if you can't see the name plate) would probably save you some bucks. Even more true if the D200 were put up on eBay. Also, it is probable that the D200 is vastly overpowered compared to how you use it. All things being equal, a lower-powered amp draws less current while idling. Obviously, sound quality won't be as great, True as long as you can see the name plate. ;-) but I can live with that. Any recommendations on specific amps (integrated or not) to look into? The main consideration is that it does need to be powerful enough to drive my Spendor s6e speakers, It's the old question, drive your Spendors doing what? it would help if you could do some measurements on the kinds of power levels that you are actually using. and preferably is within a price range that if I wanted to get one, I could sell my current amp (and maybe preamp) to pay for at least most of it. My generic amp recommendation is the Behringer A500. It is relatively small, somewhat low in cost, and sounds great. |

The Onkyo A-9555 is available at Amazon for under $500. Standby power consumption is listed at .3 W. If you actually *look* at the amp (what a concept!), "Standby" is a manually-selected mode. The OP has already eliminated that sort of thing as an energy-saving alternative. While I can't see any trace of one in the manufacturer's page, the controls and features (such as a motorized volume control) pretty much scream "Remote Control". http://www.stereophile.com/integratedamps/907onk/ confirms that the unit has a remote control. Note to OP - this sort of shallow thinking is typical of what you get when you end up relying on a high school music teacher as a technical expert :-( |

Good call. The easiest move would be to learn how to operate the power switch on the D200 more often. ;-) A valid point. I guess I'm just in the habit of getting up and walking off. I don't turn it off for the same reason most people leave their computers on all the time: laziness. I know there's another class of amplifiers that are much more energy efficient (class D ones perhaps?), and would like some options. The D200 being high end probably runs hot because the bias current flowing through the output stage is exceptionally high. Just picking a more humble amp (that probably sounds just as good if you can't see the name plate) would probably save you some bucks. Even more true if the D200 were put up on eBay. Also, it is probable that the D200 is vastly overpowered compared to how you use it. All things being equal, a lower-powered amp draws less current while idling. It does nothing most of the time, even when I'm at the computer. It plays sound effects from video games and computer beeps more than it plays music. I've considered selling off the stereo since I'm obviously not stereo hobbyist material, but I do appreciate its presence when watching a movie or in the rare case I play a CD or record. Obviously, sound quality won't be as great, True as long as you can see the name plate. ;-) Another valid point. I doubt the amplification would even have a noticeable effect if I could switch over to a cheap amp of comparable stats. The ARC products do look great, and when I bought them years ago, I admit I did so for vain reasons. I don't regret doing this much since when/if I ever do sell them, I can get most or even all of my money back as I originally bought them used on eBay. I'm still debating my course of action, but after pondering my situation, interest, and the advice here, I'm leaning towards just leaving it off most of the time, and using my cheap, crappy 5W PC speakers. This means the stereo would be completely off and save me the hassle of having to buy/swap components. It does do a great job though, so I'll keep it around and swap the output plug to it when it's movie time (I use the computer for that too). Since that rarely occurs, this is much less work than turning off the amp and linestage a couple times a day. |
