I'm partial to Steve McCormack's DNA-2 Revision A amplifier.

There's something spectacular about the bass when using XLR connections thru-out with this particular amp. I've used XLR connections with other amps, including my very highly rated McCormack DNA-2 LAE(Limited Anniversary Edition), but I've not witnessed anything close to what the DNA-2 Rev A does with those 2 additional volts from the XLR connections.

Regardless of which amp you select, you most likely would be better served if you use XLR connections. With XLR connections, the dynamics and bass are most always at least a bit better reproducing just a bit more of that live bite.

-IMO
