does battery version sound better than ac version?

Most people who have used the RA-1 feels the battery version is superior. There will always be a hiss on the AC version due to the alternating current which can get annoying. There is no such issues with the DC version. Also, it is very portable when you don't have to drag a couple with it. Cheers.
