Post Subject: It's OK because I am doing it for the wrong reasonPosted by Paul S on: 9/29/2007
I agree with your observations, and my own misgivings swirl around exactly the points you raise.  In addition, I have tried battery phono stage and all it had to offer was quieter "background", everything else was worse, despite the wild and exotic praises of the original inventors.  Likewise, battery TT was just a wet noodle; but this involves a motor, like your transport.

The truth is, at this point I have no personal reason/expectation to try the battery; I am trying it just because John highly recommends it, and maybe I harbor just a little hope that I can beat the power company for once.  But you have to know I have my own doubts, and the way I am doing it is just expensive enough that it will make me feel stupid if it doesn't work.  OTOH, if it does turn out poorly it won't be the first time I was wrong.

I got a big-ish battery, not the "flashlight" type, and it "should" serve the iDAT's more limited requirements, including enough current and run time to warm it up.  Or, I might just heat it up off the wall wart and then switch it over, since I am not messing with the old transformer supply but instead I will keep the original system intact and just basically flip a switch to go to battery.  Anyway, I will tell all after I try it.

Meanwhile, I want to solve electricity problems "globally", too.  Wouldn't THAT be nice!  I hope I get the good news right away as soon as some genius actually puts the wood to this problem.  BTW, how's the APS coming along...?

I promise to tell the good, the bad and the ugly about this battery.

I suppose the upside of my ambivalence is that this is not a situation where I am counting on the battery to make this DAC work for me.  So far I have been careful not to make irreversable changes, so I can always go back to AC if I don't like the battery, use the battery to run a robot vacuum cleaner or something.

Best regards,
Paul S
