battery powered with 'vivid' sound

I am looking for battery powered amp options that have a sound signature more vivid in nature than refined. I'm basically looking for a battery powered version of a Manley tube amp operating in triode mode (connected to a pair of ProAc 1SC). My real objective is to get my components off the grid and save the thousands of dollars I would otherwise spend on re-wiring the house, power conditioning, and cables.

I have a Red Wine Signature 30.2 that I'm trying out and there is a lot to like about it; detail and staging blow away the Manley and my acoustic jazz on vinyl is wonderful. But it comes up shy to what I want with rock and pop, it's not as emotional or involving compared to the Manley.

Suggestions?
