RE: Tri- and Quad - amping MG 3.6 + OB subs

riamp, that DEQX Pre-8 should be over-the-top especially coming from the PDC 2.6. My first DEQX for the first-generation HDP-Express (based on the PDC 2.6), then followed by the HDP-Express II, which was a total redesign and sounded significantly better than the original Express. Now I using a Larry Owens fully "Hot Rod" modded HDP-Express II which sounds best of all yet in order to crossover and correct my rebuilt/updated Apogee Full Ranges and also to time-align my GR Research/Rythmik subs. Oh yeah, I use a little bit of room correction as well under 250 Hz.

I too have been thinking about doing the DEQX Pre-8 pre-order beta tester program as well. At that price, I would hope to see a significant sound quality upgrade even over Larry Owens modded Express II. I'm not sure about the Pre-8 Dynavector designed phono section would be in comparison to my current Vinnie Rossi LIO phono section.

I know, many folks like to knock the DEQX for one reason or another. Most who do have never integrated a DEQX into their system. Yes, there are many solutions for both analog and digital electronic crossover solutions and many digital choices with room correction features as well; however, there is no solutions anywhere that I know of that can provide speaker group-delay correction - and that's what sets the DEQX apart from everyone else. Once you heard a properly configured DEQX system, before speaker correction then after, its a literally night day difference. It even makes great speakers such a the Apogees sound even better.

Is the DEQX software limiting? Maybe for some folks, but it hasn't limited me. I've been able to try countless configurations and directly A/B different crossover points and slopes. You can make your crossover slopes asymmetrical as well if you would wish. You can even play with the group delay settings as well, but out-of-the-box configuration works just fine for my setup.

Is the DEQX software basic and rudimentary and easy to master? Not at all. Yes, you can dive right in using the wizard, but even then, there is a fairly steep learning curve for even the most advanced users.

Also, if you you don't already have one, be sure to do your speaker calibrations using an Earthworks DM23 and matching DEQX correction file. This too makes a noticeable improvement over the included Dayton or Behringer mic with its generic calibration file.

Lastly, Kim Ryrie, the inventor of the DEQX is no Johnny-Come-Lately to digital audio processing. He was the co-inventor of the Fairlight CMI in 1979 and has been active in advancing digital audio ever since.
