>>absolutely unaffected by power line filth<<
First of all not all ac power can be characterized as filty. Most of us have discovered a way to cope with suspect ac power if in fact it exists.
Buying a battery powered component simply because ac power MAY be poor (operative word is MAY; it is not absolute and there are solutions if it occurs) is very poor decision making. Don't forget battery power almost always limits dynamics. There is no battery powered component I would own or sell including the garage brand mentioned here.
