a simple yet stupid ? question

I suppose so in that it needs air to move. But what abt electrical equipment? Its the electrical current so volume shld not matter? I wonder if I can just turn the volume all the way down and keep amps playing overnight etc....

I break in amplifiers by running them with a 20Hz worble tone into teh speaker. This way the amplifier is having to do real work. Maybe it is just teh logic behind it but it sounds like it works to me. Who knows?

Volume matters on amps..to some extent. Keep in mind, if there is no preamp volume then the amps are functionally receiving a nil signal. Just my opinion but I believe it matters on solid state moreso than tubes.

But if so, then does it mean the louder, the faster the break in for amps?

Use the Ayre Acoustics "Irrational But Efficacious" disc. Put on track 7 ( Cardas sweep tone ), hit repeat and play it at a volume that is reasonably high yet safe for your equipment. Be forewarned that this track is capable of not only damaging your system, but also shaking things in your room / off of the wall if your speakers are capable of it.

I don't know of any other method that is as efficient, effective and simple to use. It can be VERY annoying to listen to though, so it works best if everyone is out of the house, etc... The longer that you can use it continuously, the better the results. This will work out the entire system. Sean
