Has anyone used a full-system battery power supply?


It seems to me that the biggest problem in most high quality hi-fi systems is dirty power. My AC power in Vermont is weak and dirty. Has anyone ever heard of a massive battery power supply that could provide power to a whole system? Rowland uses them, and there are some newer phono preamps that use them. I am not very technical, so I don't even know if this is technicially possible. I have owned a PS Audio P300, and I didn't feel that it gave me $1200 of improvement. I also owned a Custom Power Cord Co. power conditioner and heard no real improvement--just minor differences. I owned a battery powered Camelot phono stage which was great until it crapped out in two weeks and I had to return it. Any thoughts on this mega-battery power supply?

It would be possiable to put an amp on batteries. An 100 watt SS amp typically has a power supply of around 60 volts plus and minus. If you put 5 car batteries in series for the +60 and another 5 for the -60 power supply rails, the amp would play for several hours before needing the batteries recharged. The charging system is no easy task for that many batteries in series but for testing purposes just start out with fresh batteries. I think it would produce killer sound and would be easy to hook up on most SS amps. The 300+ volts on most tube amps would require even more batteries and would likely be unfeasiable. Chris
They make battery systems for this purpose. The can be plugged into the wall and charged and last several hours. I saw one once at my local hi fi dealer but I have no idea who made it
Perfect: defense industry contractors make the best. Used in submarines & the like. As you note, you plug them in & the equip in them. The amperage is not always very high, though. The ones I've seen are HUGE, ugly, best left hidden somewhere...

In Europe they come reasonably cheap: ~$1k for a 12amp that can last 3-4 hrs unplugged. Maintenance every 2-3 yrs.

Never tried one -- maybe I should.
