This is just my 2c.
I personally love DCs since they have one of the absolutely best warranties out there.
But if you buy DC, Bose, Zulu's, clarities is basically your own preference. But if i could offer you my point. I go through batteries like no other.
Either invest in a good rechargeable batteries with a travel charger or invest in a panel power, CRJs, ERJs, Airbus and Boeings use them so that is at least my goal going forward.
