Is DEQX a game changer?

handymann,
That experience is discouraging.  I was considering a DEQX for a 2 channel area but don't have the time, patience or expertise to do it on my own.
I just installed a Lyngdorf MP-50 (with RoomPerfect) 16 channel processor in my dedicated and treated theater and am very happy with the improvement over my Marantz-8802A.
For a separate 2 channel system, I was thinking about the Lyngdorf TDAI-3400 integrated for RoomPerfect and am intrigued by the HDP-5.
They are in the same ballpark cost-wise and I have amps to use
with the HDP-5.
Without (dedicated) support the HDP-5 is probably not a good option for me.

interesting on the dbx.
I just ordered a dbx driverack PA2 to use to biamp some omni speakers to play around with.  The dbx was recommended by the speaker manufacturer.

ToddCowles,
Thanks for the input.
The Lyngdorf 3400 is an integrated amp, not a pre-pro in the home theater sense.  It is roon ready as is the HDP-5. To me the HDP-5 would be a preamp, essentially used like the Lyngdorf but I'd use my own amps, as I have extra amps to use.  If I had the Lyngdorf I would use its amp.
I understand you had a good experience with Larry but it seems there were 2 people in this thread that the speaker calibration part was skipped, thus not utilizing what seems to be one of its most attractive features. Thus, the DEXPert mentioned most in this thread seemed less than ideal.  The poster handyman above ultimately returned his unit after his experience.
The DEQX technology is fascinating to me and I'm still considering it.  

Drewan77,
I have read this whole thread and very impressed with your knowledge and generosity of your time and input.  Your DEQX enthusiasm is one reason why I've looked into it.
