Room correction - what device works best?

Looking at room correction and all the threads I found seem old. What are the current options for excellent 2 channel sound. Comments on DSpeaker, Lyndorf, DEQX, Audessy, Rives and others welcome. I have option for using in digital domain or putting between pre and amps. Would of course prefer great sound at lower price. Also prefer something that does not take a year of obsessive fiddling to get right. Have a very large family room, so room treatment options limited. Current system is Ayon Cd5s (transport, DAC and pre combined), Nuforce Ref 20 mono amps and Von Schweikert VR55 speakers. Is most of the bang for buck in correcting for room modes or is speaker phase issues also necessary? Eventually in may have subs but not now.

To the question of time alignment for speakers with passive crossovers, these quotes from the PreMate review should clarify things. From the Positive Feedback review:

... it corrects for …."the distortion that all speakers make—electro-mechanical devices that they are—and offer room compensation as an added extra. While righting frequency-response errors as other units do, they also uniquely correct critical timing errors by adjusting thousands of frequency groups so that they arrive on time.

"In correcting the speakers—before the room—our comprehensive DEQX-Cal™ software generates correction filters for phase, timing coherence and frequency-response. Only then does DEQX-Cal measure from the listening area for room correction.

"It corrects speaker frequency-response and timing errors by adjusting thousands of frequency groups, depending on your speakers' measure­ments, so that they arrive at the correct time."

Doesn't get much clearer than that.

It appears as though unlike DEQX, DIRAC does not offer cross-over features.

Currently, DIRAC does not offer cross-overs or bass management, both of which must be implemented prior to DIRAC processing.

Its still too bad the DEQX requires the movement of the speakers and consultation to obtain best results.

My current speakers weigh 215lb each and have spiked feet.

Perhaps sometime in the not too distant future there will be a more user friendlier version.

In the meantime, I'll stay on the sidelines awaiting Almarg's adventure.
