Hi, yes I also use battery powered stuff. I like it alot. I even use battery power on my power amp. If it is lacking in any transients/dynamics/bass impact, I sure don't know about it. IMO, it is superior to what comes out of the wall any day of the week. I get instantaneous current delivery like you wouldn't believe. Zero grunge. No power transformer hum fields. No rectification or ripple. Pretty damn good in my opinion. I wouldn't go back to wall power again. I'm using lead acid RV/marine type batteries with over 650 cold-cranking amps and deep-cycle capability. These babies rock! And they really keep the noise floor dead quiet. Of course, I'm only powering a 2 watt 45 OTL SET with them that draws 3.8amps at 12vdc, so you could say that I have plenty of reserve power. Probably won't be drawing too hard on those 650CCA anytime. But if they can surge 650a, I think they'll deliver 3.8a pretty freely. My dynamics and bass impact are plenty good. No problems at all.
