Battery powered DAC

Hey Chris--

The battery thing is a major drawback in the convenience department as far as I'm concerned.

Couldn't you just hook the dAck up to one of those nice dry cell batteries that serious car audio guys use for amp power? No fumes,no acid on the living room carpet, charge it once a month (or less) off the battery charger you already have in the garage. Designed as a deep cycle, so even full discharge wouldn't hurt it, stable, economical (well, $120 or so)- you could hide it in a closet and run a power lead to it.

Would there be any improvement in dynamics? If the thing sounds good with a tiny Li-ion battery pack that is rated 1.3ah, wouldn't a battery with 660 cold cranking amps basically be a super-stiff power supply, or is the little battery pack already plenty stiff?

No, I'm not kidding.

Thanks Chris--I'll look for the "new and improved" unit to solve the recharging issue.

ROOX: I wish I listened that much, but the fact is, the CD player is on that much for background-- cooking dinner, eating, working after dinner, reading and some real listening, too. I wouldn't want to have to suffer with built in DACs during this less critical listening. I've also got enough stuff to remember without having to make sure I put my dAck! to bed properly lest I harm its delicate batteries.

I'd be interested in a unit with AC power that didn't have to be put to bed every night, and maybe a switch for critical listening to disconnect the AC and run on battery power only.
