What's The Big Deal About Battery Powered Preamps?


.
What advantages do battery powered preamps have over the traditional plug-in-the-wall preamps? I just read recently where Red Wine Audio is coming out with a battery powered amplifier.

If the preamp is otherwise well designed, a battery power supply lends a very low noise floor. The importance of low noise at the preamp stage cannot be overstated - as noise and distortion are additive, and the amplifier magnifies the input signal from the preamp, preamp noise and source noise are particularly deleterious.
