Battery powered DAC

i have had private correspondences w/chris - wery responsive. he told me he could provide bigger batteries w/an enlarged case for ~$100 more, that would hold a charge a lot longer. he also said he could configure it to easily hook up to a lab-grade dc power supply, of which there are a myriad awailable on ebay for pennies on the dollar. this is what i would likely do, as i cannot realistically see myself *ever* being willing to deal w/a battery power supply. i presently use a ~$1200 hewlett packard 0-20vdc, 1-4a power supply to drive my turntable's origin-live dc motor kit. i picked it up for ~$100, & it's a noticable improvement over the stock o-l supply... chris sez he cannot say for sure how a typical lab p/s would compare w/the battery supply. i think he needs to try one & see - enquiring minds wanna know! are ya listening, chris? :>)

i may have to try an ack!, to see how it compares to my self-modded art di/o. but, to be honest, i don't really have any overwhelming urge, since the di/o has aquitted itself so well against the likes of resolution audio & electrocompaniet cd players. but, the ack! certainly *looks* cool! :>)

colin, the stereo chez-sedon typically gets turned on at ~7 am, & doesn't get turned off 'til midnite, later on weekends. even if fm or winyl is playing, everything's always on, & i wouldn't wanna have to be futzing w/whether or not a battery needs charging. but, fact is, the cd *is* on a lot, the wife typically loads 5 discs into the changer & hits "shuffle", and has background music on all day.

i'm not the only one in the house that enjoys the rig - even the kids, 8 & almost 12, use it. fortunately, they are too short to reach the turntable! ;~)
