I have a VK-50SE and I love it. But ARC and BAT sound different. If you like the ARC you might not like the BAT. Buying equipment at this level often decided by personal preference rather than clean cut sonic advantage. I think you should borrow one for a home trial or at least listen to it before making a decision.
BTW, when you audition the VK-50SE, make sure it is well broken in. A brand new unit sounds like a bad solid state.
