Battery power supply

PS Audio Power Plant might be a better choice for your front-end at home. But do consider 30 day return policy: listen for a few weeks with Power Plant on, then disconnect and listen again... It took me a few years to do so, and I sold it here within a month after going thru such non-scientific, non-ABX, or double-blind test. But the initial impression of getting a perfect sinewave for my player/hp amp was WOW!!! Then there was another Wow! when I got it out...
