The Beheringer NX3000D seems to be exactly the same as my old iNuke 3000DSP, with at small number of changes.
The USB interface is moved to the back, and The case has been changed to a black finish, with metal front. It feels a bit more professionel than the old iNuke amps.
A internal change that i have noticed however, is that the NX series seems to have temperature monitoring, and unfortunately this puts the amplifier in protection mode if temperature is below 0 degree Celsius, making this not as versatile as the old iNuke, that could handle almost any condition.
My only complaint about this amplifier is the same as with the iNukes, the build in FAN is not low-noise, its not bad for stage use, but its annoying for use in small rooms when the music is low. This can however be fixed by changing the FAN, like i have done in my older iNuke amplifiers.
But overall a good follow up to the iNuke series amplifiers.
