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.

Gammajo: Let me clarify, avoid Auddyssey.

Vandersteen summed up my views quite well after that disaster. See

I just want to thank everyone for making this thread intelligent, informative, encouraging and respectful. I had begun to fade my time on A'gon after too many uninformed opinions delivered with vitriol on too many threads. I am learning something here where the passion for excellent sound is trumping egos.
Unsound ... in a way ... yes. I used my ARC CD-8 CDP as a transport and ran its digital output directly into the DEQX's digital input. On the margin, maybe a little better going "digital" direct as compared to using the CD-8's analogue output into the Ref 5 SE.

Nevertheless, I still use my ARC Ref 5 SE because it is a convenient way to handle other input sources, e.g., phono and TV. IMO, I think the close CDP performance says a lot about ARC gear quality.

Also ... though not logical, I can't bear the thought that my Ref 5 SE may be obsolete. :(
