Excerpt: I have 4 NU6000 and 2 NU4 6000 I have used these on several shows in different variations. I just got done running a big show using only 2 NU6000 and 1 NU4 6000 to power up 16 16ohm biamp line array cabs, prossessed through 1 DBX driverack pro. These never clipped and ran cool. The low damping factor of these amps delivered a clear sound with only 30 amps of consumption. Nice job on these amps and looking forward to the NU12000 coming soon.
