What's The Big Deal About Battery Powered Preamps?

my preamp can take a battery input (Nagra PLL) I've had a Red Wine Audio Black lighting at home. The battery gave a much improved pace and rhythm, lower noise floor, improved dynamics all for a low cost. My current AC cords (Shunyata King Cobra with a Shunyata Triton) may beat it (it's very close however) but at 8-10x the cost.

It's worth hearing what well done battery set up can do...

Red Wine also has a battery powered amplifier. Don't you need juice from the wall socket to get serious power from an amplifer??

The main reason for a battery power preamp is to avoid any type of contamination that occurs with ac power. I'm sure you have noticed all of the different types of line conditioners and power cords that are on the market. With batteries, you avoid all of that. Also, the preamp runs on DC which eliminates the need to rectify.

Jfrech,

Your comment about improved prat with a battery preamp is very interesting. If anything, I would have thought it would be the opposite. If that's the case, I might try one myself.
