Post Subject: Battery for the iDAT-44+Posted by Paul S on: 10/13/2007
Like I said above, I planned from the start to try battery power just because John Wright recommended it, and it seemed like up to that point we were talking the same language, which was borne out when i listened to the unit as I received it. So, I did not have targeted objectives that prompted the switch to battery.
I did some research and wound up with an Odyssey 625PC battery (12V, 17 Ah) and an Odyssey 6V charger. I made up a DC adaptor for the iDAT and got evrything set out. I started out by warming up the iDAT with its transformer, then I listened with the transformer, then went to battery, then back to tranny, then battery again.
In this case I will use the battery all the time because it makes better sound and better music. It either eliminates or greatly reduces the sort of cotton-y quality that normally serves to surround notes, and the whole spectrum is clearer, better timed, better "harmonics" and either much better dynamics or a better representation of dynamics because the broad-spectrum noise is pretty much gone. The acoustic environment is expanded out with the sound.
Basically, it's all good at this point. After 3 hours of play time the battery still measured 12.65 V.
I think the iDAT-44+ has a pretty simple power supply; the unit is small.
As a point of reference, electricity was good today.
