Is DEQX a game changer?

Al, for the configuration you plan on using you won't need to worry about any manual time alignment as the 3 sets of outputs won't be feeding multiple power amps or subs (which is what they are really designed for). The only graphs you will need to interpret manually will be the in-room measurements at the listening position and that's very easy

That makes your setup much simpler as the HDP-4 will automate correction to speaker drivers driven by one power amp. It will hear your speakers as a single set of frequencies with any passive crossovers included in the signal path and adjust accordingly. You won't use the active crossover facility, just speaker correction to one stereo pair and the potential for room equalisation as you see fit

At a later date you have the opportunity to try all the other features, adding more power amps, speakers without passive crossovers, maybe subs etc. As long as you always measure with the power amps and cables linked to the drivers they will be running, you can even use different brands and wattages of amps for bass-mid-treble and DEQX calibrates and adjusts accordingly. Better to stick to one brand/rating though but it does allow you to adapt the system without needing to purchase 3 new sets of power amps in one hit

Hi Guys, I have read several post, but not near all, this may have been addressed. I have no doubt that the DEQX could be a game changer, but it would require Biamping, triamping etc.
The biggest problem in any speaker is the crossover. Coils suck the life out of music. If you are willing to remove your speakers crossovers, run an amp channel on each driver, properly set up the electronic crossover, then adjust time delay and eq to your room, there is no doubt that any of us will have performance that we have only dreamed about.... assuming that the DEQX is clean and does not mess up the sound of the other electronics in the system. Unfortunately for me, this is a product out of my reach... I have found a substitute that I will be trying shortly, it is called Mini-DSP... I have purchased it. It comes in 2 to I believe up to 10 Channels... I have gutted my speakers crossovers, but have decided to do some cabinet work so it will be some time before I get it all up and running... I can't imagine the Mini DSP doing anywhere near the job of the DEQX, but it does have full electronic crossovers, full eq capabilities and full room correction software with a calibrated mic available. I'm excited to give it a try and very curious to see if anyone else has tried this inexpensive product?
Thanks, Tim

Has anyone tried putting a High Fidelity Cable Ultimate Reference Rhodium power cord on their DEQX? I'm just curious as to the effect that putting a game changing power cord on a game changing piece of electronic gear may sound like.
Could be that two 180's = 360 and put you right back where you started???

Cheers,
John

Right John. Going in circles.

Andrew (Drewan77), awesome! Thanks!

Hi Guys, I have read several post, but not near all, this may have been addressed. I have no doubt that the DEQX could be a game changer, but it would require Biamping, triamping etc.

Tim, my hope and expectation, based on the inputs from several DEQX users in this thread, and on Kal's review, and on the comments on time coherence by Bombaywalla and others in this thread and the recent "sloped baffle" thread, is that that is not the case. My Daedalus Ulysses speakers are not even biwirable or biampable, having just a single pair of terminals. Designer Lou Hinkley doesn't want users doing those things, and in the process risking introducing compromises to what he has worked hard to achieve. I simply hope and expect that the sophisticated time alignment and room correction features of the DEQX, and possibly a little bit of additional equalization here and there, will enhance the already good sound I am getting from them to a significant degree. As well as perhaps also providing an upgrade to my preamp, and maybe even to the DAC and analog sections of my CDP.

As Kal said in the conclusion of his review:

It made my very good speakers undeniably better, smoother and cleaner, and endowed them with a bigger soundstage. It mad dense complicated music easier to resolve, and all music more of a joy to hear.

Best of luck with the Mini-DSP, btw. I am not familiar with it.

BTW, I'll add to my previous comments about the system configuration in which I intend to use the DEQX that I do not envision adding subs in the foreseeable future. A majority of Ulysses owners do not use them with subs, although Lou offers what is apparently quite a good (and somewhat expensive) passive sub that is designed to mate with them. But the Ulysses are rated down to 28 Hz +/-2 db, which is good enough for me. And that rating seems consistent with evaluations I have performed using test tones, as well as listening to well recorded organ music, etc.

John, LOL! :-) I wonder what the "three amigos" would have to say about that. (To the others, that's an inside joke; don't ask). Come to think of it, though, I don't want to know :-)

Best regards,
