Behringer DEQ2496 vs. DSP8024 as DAC


I just got a Behringer DSP8024 digital EQ on an impulse and am loving the room correction. I'm using it as a DAC for my HK8550 CD changer. Didn't know what to expect, so I jumped on an eBay bargain rather invest in the reportedly better DEQ2496. I was planning to use it solely for bass correction in my biwired & biamped system, but I'm loving the full-range EQ.

My question is, is the DEQ2496 an audibly better DAC than the DSP8024? Anyone have experience with both? I'm feeding it to Martin Logan Aerius i's through an Adcom GFP-555 and a pair of Adcom GFA-5200s in a 12x19x9 living room at modest listening levels.

Any first-hand info would be much appreciated.

I used an 8024 for a while in an InnerSound Eros system for a while and could not get the system to sound good when the 8024 was in it. It was always bright and zingy to my ears. I ended up sending the 8024 back and never regretted it for an instant.

The 2496 is supposed to be better, sonically, but I have not heard it, so can only report what others have said.

Perhaps someone else could offer a direct comparison between the two. Personally, I wouldn't use an 8024 for anything other than bass EQ. YMMV.
Bright and zingy? Was that the Auto-Q result? Did you try manually adjusting the curve after doing the Auto-Q? I found the Auto-Q result to be understandable, but a bit bright. I moderated the curve by 1db (raising dips and lowering peaks, except in the bass), and this restored just the right amount of the Aeriuses' warmth. Not bright and zingy now.

Also, did you use it as a DAC, or did you insert it into the analog chain? The former has the theoretical advantage that the digital signal from the CD player is EQed while still in the digital domain, and the signal then goes through D/A conversion only once on its way to the preamp. If you put the EQ into a tape or processor loop, the CD player or outboard DAC converts the digital signal to analog, and then the Behringer converts it back to digital, EQs it, and then converts it to analog again. Three D/A conversions can't be a good thing.

Any comments on its relative merits as a DAC? I'm finding its EQ functionality thoroughly agreeable. I'm just curious whether the DEQ2496's DAC might be audibly better. I've got a cheapo HK CD changer and have never had the chance to A-B against a higher-end player or DAC, so I don't know what to expect or listen for, or how big a difference a DAC upgrade might make. Is the Behringer's DAC comparable to the HK's? A Rega Planet's? A $500 outboard DAC? I just have no idea.
I could not get the 8024 to sound good in my system no matter what I did, even with manual tweaking of the controls. I don't remember if I tried it as a DAC, but I think I did. This was about 4 years ago. My main memory was that my system sounded much better after the 8024 was removed from it.
Well, my HK CD changer is not exactly hot stuff, so maybe there's nowhere to go but up. The room EQ improvement certainly outweighs any signal degradation, as I can hear the former clearly and the latter not at all. That's why I'm interested in knowing if the DEQ2496 is any better. I was planning on eventually getting a Rega Planet 2000, but now I'm not sure if I can live without the EQ, and if the CD player is being used only as a transport into a Behringer DAC, I suspect the main advantage of the Planet is lost. Perhaps feeding the Behringer into a proper outboard DAC is the way to go. Any addition to the front end can't cost more than $500, though, as I've got to squirrel away $3,000 for a new Mac.
