It is entirely possible the DCX2496 was defective, or you just had some funky groundloop induced by some combination of gear.
Problem is the DCX2496 is also limited to 20hz and will run out of CPU if too many things are enabled.

FIR is measurably better, especially with a RePhase IR-convolution plugin or file import.
The only downside is the time delay that linear-phase demands, generally 20-50ms if I recall.
I heard it also has a problem handling infrasonic frequencies, that's not something I've had a chance to test yet with the FIR tools I have, the miniDSP may be slightly different results.

Any pro equipment is much better off if you can run it without a DAW/computer actually on. I would only want those connections for setup, but not for actually having the thing work. That's seriously overkill.
I agree one should, *if* they could...
The problem is that the RME, Antelope, Motu etc... none of those have on-board XO's or HPF (especially below 20hz). 5 bands of EQ at-best.
So we are forced to for higher channels counts or for anyone wanting infrasonic DSP.
The pro industry has moved towards DSP-amps and everyone is cool with their 20hz DSP limitations. What can a ULF-basshead do...
Although that WAS like 1-2 years ago last I checked all their product lines, maybe now they have a product out that does that? One could dream!
I happen to enjoy the 3-10hz region, even as inefficient as it is. So that's sort-of a limitation I'd like to avoid if possible (and it is possible.
I'd rather have a Trinnov, but wouldn't we all!!! Short of that, I'm not sure it is overkill. What scared me away from the miniDSP was AVS'ers complaining about noise and limited output voltage or resulting clipping thereof. I didn't want noise on my LCR's being 108db/w/m SEOS's. That and, I can do matrix Atmos with the rig, creating phantom channels that don't normally exist, such as: rear center, rear center height, tri-channel bass support, and low noise for LCR tweeters. Routing any channel (or combinations thereof) to any driver. All via network on-screen from my chair. (Never having to touch another wire again!)
I'd have to buy 4 or 5 miniDSP 10x10's and downmix XLR to RCA, and back up again, and the extra noise that causes, lose 80% the routing, and fart around with USB cables and software connections.
If you want Left bass signal from the 1st 10x10 to the 4th 10x10, now you have to re-wire it with physical cable (can't do it from a chair, have to make a trip to the hardware store to get more RCA cable etc.)
and that would be additional cascaded delay + noise too, and you'd lose 1 channel of DSP for every out-of-box routed connection.
For people without active speakers or only 4 subs, I suppose those limitations aren't encountered.
In a bigger system, say with 32 subs + active speakers, 4 or 5 10x10's still end up being like $3000, that is a LOT of money to spend to still be unhappy with. It was enough to scare me away at least...
