Behringer NX6000D

Used in Home HiFi set up to power sub woofer, so I cannot comment regarding Live PA use or full range. This replaces a pair of NU3000DSP's which have run trouble-free for the last 5 years. The fans need to be changed for the home environment, but plenty of info on how to do this online.
The NX range represents a cosmetic improvement over the NU's and now includes impedance stabilisation which I gather only affects upper frequencies. Other than that, the electronics are identical.
For sub use this unit has plenty of power driving a pair of relatively inefficient UM18's in open baffle configuration. They have never sounded better, and will extend sub-sonically with appropriate material.
The sound of the bass is well controlled, textured, fast and detailed, possibly helped by the OB.
Setting up couldn't be easier with the Behringer Remote software. Only wish it was compatible with the old NU series as I had to transfer my programs over by hand. The only complaint I have!
The elitists will talk badly about Behringer, but I only have praise.

So the good - its a great amp, lots of thump. Never used the on board screen for selecting modes as its a bit small, always plug in my tablet for the DSP features - all good. Light amp, better efficiency that my other 40kg amps.
And the other side - the fans are reasonably loud. Mine has had to be returned (luckily I had ordered another before it broke as I loved the amp and had more subs to power, so I wasn't without an amp), not sure what may have gone wrong, the load was only flickering the first signal light, so not power related, but the returns process has been great, and free.
A pernickety point, my gain controls are not equal in their notches. 6 notches on one side may equate to 6.5 on the other - minor point, and nothing to worry about.
The second NX-6000D I got is running flawlessly.
The NX6000D suited my sub configuration, if you are running large PA low/high speakers, or 4 lowish power 2 ohm total subs, you may want to consider the NX4-6000, 4 channels, but I don't think they do it with a DSP.
