Anyone have experience with a DEQX?

Been diligently saving up for one of these puppies. Just like accurate horn speaker and digital amplifier accounts, I find, few if any, detailed reviews of this product.
I firmly believe the combination of this processor type and a high power chip amp, with digital path from source to speaker, to be pro-audio nirvana. I have an SVS AS-EQ1, and what it does for the subwoofer is fantastic. I can only imagine what something that could handle the full gamut would sound like.
Would appreciate anyone's first-hand experiences with one.

First I have to say that I do not have any experience with this unit. It does look interesting though. I suspect that a device like this would be of more use in a home system or on a pair of studio monitors while fine tuning a mix in DAW software. For PA use I do not see the value of it. As you walk around the room phase and timing issues change, in home audio or for monitors you are in the sweet spot, that's the big difference. IMHO A Driverack, the Behinger combo, or XTi's would be a much better way to go for PA use.

That is good. Somehow I missed home use as the intended application. I looked at a few of the dealer links but in each case the price was not specified. Usually in high end audio if there is no price stated you don't want to know. A BBE-DS24 or 26 make a great crossover for home stereo. Sonically the units are excellent and will not degrade the sound of a high end system. The unit has delay for doing time alignment, you just have to do it manually. The parametric eq's let you flatten the speakers response.
I have the BBE DS24 and use it at home, right now it is in my office doing monitor duty as I edit some tracks. It also can serve as a backup for the Driverack PA+ in my PA system if it is ever needed. I like redundancy and whenever I can work it in without compromise I do. Best of all I paid less then $200 new for the BBE. I don't think that it can be beat for the money. You do have to look around for sales as they are listed for a much higher price in many online stores.

$2000-$4500 Depending on what model you get and with what sampling equipment you go with. This is not "high-end" by any stretch of the imagination. It is prudent electronic application.
The result happens to sound "high-end" because what high-end actually is, for lack of better terms, is linearizing the transient response in the frequency domain, minimizing reflections by respecting directivity, keeping distortion acceptably low [both signal and IM] , making the frequency response palatable for the listener, and having enough headroom in the gain structure to faithfully replicate the dynamics of the input signal. Granted, some of this is electronics, some of it mechanics...of course, feel free to correct me if I've missed something.
For that price and some know-how, one can have sound only once obtainable with
very expensive systems...for peanuts in comparison, because the cat's out of the bag.

Gee....when my stereo doesn't sound right.....I turn it up. And if that doesn't fix it - I turn it up some more.

Bill's kick-butt designs and this forum's wealth of knowledge and wonderful people to thank for, plus no kids.

Cars were paid off years ago...no mortage. When I can build great sounding speakers for less than $300, I've got some coin left over for the things I can't cobble together myself....like a black-box DSP.

Screw that expensive store bought crap.
DRC on a $300 home built PC FTW.
