Re: Why/how do better power supplies benefit audio gear?

Well, a lot of people tend to underestimate the importance of the power supply, because it's "Not in the signal path". Well, technically, it isn't, BUT . . . it IS the path!

In other words, any noise in that power supply is going to make some kind of AC signal, however faint. You want to get as pure a DC as possible, which should measure as a pure straight line on a scope.

While getting it to go away totally may be impossible, even with batteries, a good power supply can be so quiet that it effectively doesn't affect the signal at all.

Try this sometime: no signal applied, crank everything all the way up. If you can hear anything, even if you have to get up close (make sure no one else is gonna press "play" on anything!), most of what you will be hearing is your power supply, as well as any noise it picks up from the "outside world".

Hope this helps, my brain is tired.

Hmm, that line up top could be kind of catchy, I might have to hang on to it for when/if I get my company off the ground: "The power supply isn't in the signal path, it IS the path!"

Nite every one,
