Bought a gxd 8 two years ago still rocks!

Decided to do my dissertation review on this amp after 2 years of use! Give a shout out to my dude Nate Kaughman for always taking care of me with the gear needs! This is a great amp. The dsp features practically makes this a "smart" amp. I use an external eq just easier. Built in adjustable crossover and limiter is nice.
You can even adjust the power output and ohm select which I find impressive. Great amp its clean powerful and doesn't disappoint. Considering getting a second.
Cheers!

Rated 5/5

Honest power in a compact package.

Sounds as good as my other high quality amps (PLD, Crest Pro Series/CA series, Icepower, etc).

Fan is nearly silent. Happy surprise.

DSP is simple to use and effective for general processing.

Feels rugged.

Definitely delivers adequate power in agreement with what you would expect based on the numbers. I set the limiters to "mild" and max power for extra kick into the subs. Good limiting behavior.

If the features match your needs, you won't be disappointed.
Rated 4.5/5

Great amp.

I'm going to get the bad out of the way first.
Not having a DSP editing software I can load on my laptop just sucks and if your not using QSC E series speakers this makes management slow and tedious. I don't like how QCS doesn't have a bridge mode, at least that I have found supported by manufacturer. Also my unit at least was kinda tight going into the 19" rack.

Now other than what I listed above the amp is amazing, it's clean and has more than enough power to push speakers the way they want to be pushed. Not mush else to say about it other than the sound clearly makes it worth my small complaints.
