I lowered my noise floor on the cheap........

I run a dual use system so I run a APC battery back up incase of power interuption so i can shut down Projector and let fan cool bulb to avoid damage. So I got bored and wondered what if any improvement I would get if I ran Phono Stage into that unit and unpugged it to run on DC so after I fished wires, I unplugged the backup shut off alarm and listened for near 3 hours enjoying the dead silent back ground I never had before, all hum was gone. I dont have a super awesome analog rig, SOTA Star/Saphire tweaked Rega 300 arm, AT oc150 cart and Musical Surroundings Phono with Kimber Hero wire but man it was really easy to hear the imediate improvement..........not sure how much over 3 hrs I can listen on battery but it was a cool upgrade, Cheers

That is a neat experiment , a friend of mine converted almost his whole system over to battery power except for the power amp. He had about a dozen gell cell batterys sitting on the floor all around his system. I haven't seen him in years he since moved away and lost touch with him, but that was the quietest system i had ever heard. The background was absolutely pitch black .From what i remember he could go a week or so before he would recharge the batts.
I recently purchased a Moon Audio 5.3 phono preamp that has a outboard DC plug in . I am waiting for Moon to come out with this outboard DC upgrade i am hoping it is a battery powered option cause this is a super quiet preamp and if it were battery powered it would be awesome.
