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.

I understand that not everyone's significant other is cool with having a lot of tube traps and acoustic wall panels in their living room--and I count my wife among them. That's why I use Lyngdorf's RoomPerfect room correction system and it's simple to set up and use, plus the results are gratifying.

I have also used a fairly basic dbx 31-band stereo graphic equalizer with very good results... but usually you need a way of measuring the resulting response curve and it is done manually, band by band whereas the Lyngdorf does it automatically using measurements you take around your room with the included microphone.

From what I understand the DSpeaker EQ only adjusts frequencies from 500Hz and lower, and the Rives unit, while it is reputed to be fairly transparent, is also limited to what it can do, and I believe it only works in the bass. The Lyngdorf works full-range and reduces room reflections which can improve the fine detailing and imaging quite a bit. There is a lot of flexibility as to the adjustments you can make to the sound via remote control from your listening position, and that's another reason why I like it. It also has a bypass button so you can instantly compare the direct input signal to the EQ settings. For me this makes it a no-brainer.

While the Lyngdorf is not inexpensive, neither are acoustic panels, diffusers, helmholz resonators or tube traps... and none of those devices may work at the specific frequencies that your particular room needs corrected.

Many audiophiles are "purists" at heart, and as such are closed-minded to anything that does not fit their purist mindset. In the case of room acoustics and EQ keep in mind that most of the people giving advise have little or no experience working with electronic EQ. Even if they have tried electronic room equalization, there is a learning curve and they may have given up before they fully understood how to use their device effectively. That said, it's not exactly rocket science.

Everything I read indicates that the Dirac system is the way to go. Do some research and see if you agree...

RW, nevermind the research... have you actually used the product in your own system and if so what was your experience? If not, well, maybe you shouldn't be touting it...
I completely agree with Plato and RW is correct. Audio is technology and must be corrected them with electronic engineering. The last thing I want is to tweak and install Pads on my wall because it just telling people that my system needs help.
As far as I can tell, I have used all of the devices so far mentioned (as well as some others) and, honestly, they all work. The variables are:
1. Bass only or full range.
2. Analog only, analog in/out DSP or digital in/out DSP
3. Automatic implementation of filters from measurements or independent measurement and implementation (more hands on).
4. Single measurement point or multiple measurement points.
5. Single pass listening area measurement/correction or separate near-field correction followed by room correction.
6. Fixed or variable target curves.
7. Stereo or multichannel.
8. Hardware or software.

What device works best? Depends on your choices and your room acoustics.
