Well, my 6000DSP arrived yesterday evening.
I rewired my LMS's coils from 1 ohm to 4 ohm and swapped out my CE4000. At first test I almost bottomed my LMS due to having the inputs/outputs transposed, I thought the wrath of god came down! It was so loud I got the bejeesus scared out of me! That was almost a very costly mistake.
After a reasonable effort to get things level matched, it seems like a good trade off. The CE definitely holds its own and is no slouch despite being down close to a 1000w at 4 ohm or at least in theory.
I could definitely tell the difference in power with my shakers, which I believe I have them wired to present an ~8 ohm load. I had to dial them back 12 db right off the bat to get the levels close.
Damn, those LEDs are bright though! I didn't find the fans all that loud when 13-14' away and in an open backed cabinet, but I will definitely be doing the fan swap if I keep it. There is quite a bit of air flow exiting the front so a small reduction should matter little.
The thing is so small and light that it feels like a toy! I think it is like 20lbs lighter, and a lot shallower. It is a huge space saver when compared to the CE! Two iNukes would barely be larger than one CE and a third less weight!
It's a pity you can't bridge these guys but ~2100+ watts at 4 ohm is impressive for something this small and light. The DSP is a lot like the DCX so pretty straightforward and simple to use, albeit I have no plans/needs to use it at the moment.
A ran a few more scenes doing some A/B testing and I couldn't detect any glaring differences in audio quality. At first it seemed like the CE had a little more fullness (for lack of a better descriptor) at the very bottom end, but that may have been a placebo. I tested a few more times and they sounded 99% the same that I could tell. I hope to do some additional testing this weekend, time permitting.
However, it looks like the iNuke is a hell of a deal for under $400! I might just pick up another and not look back....or wait for the 12000 despite the fact that I surely don't need
