I can not live without "Room Correction"

Hi I too tried digital room correction but found that the " price " by gaining a better tonal balance was too high. The perspective was partwise comprimised and regarding analog playback, i Got a digital print in the soundstage.
my soulution was passive roomcorrection, a part from optimal speaker and lisining position, i build passive loudspeaker absorbends to minimize the stranding waves isue. Adding 2 pairs of Shakti hallograps, one set behind the speakers and one set in the sides where the first reflection occured also made a significant improvement. It was also a good improvement to remove the system from between the speakers to the sidewall as well as hanging it on the brickwall and place a lot of decoupling under it.
its my beleafe that putting in another DAC in the system easily males a lot of mess. The passive way isent much cheaper but certaintly a heavy task to build and it tales a lot of time too.
happy lisining

MathAudioRoomEQ and Room EQ Wizard are both free.  I use the former and couldn't live w/o it.  My living situation requires the stereo to be in a small bedroom and the difference between raw and treated is dramatic.

There may be other trade-offs, but the big ones are overwhelming positive.

I have found that room correction is really based on the quality of the speakers used.  Some 'lesser' speakers see improvement as I have found when I had the new SVS Ultra Towers for a few months and used the Anthem ARC software; it really helped these speakers do a smoother job.  
Then I got in some Bryston Middle T speakers and found that no matter what I did with trying multiple scans of the room, the ARC mudded up the speakers, so I ran it without room correction and the Bryston Middle T's sounded wonderful.    A few months later I got a pair of gorgeous Santos Rosewood Bryston Model T's and hands down, NO ARC needed at all.  The T's are just perfect.  
My brother who I rarely see came for a visit this past July.  He's a video/sound engineer-producer and he has never seen or heard the Bryston Model T speakers.  When I put on some high dynamic range music from the 80's-analog of course, he was blown away.  He used to work with some of the major bands with live concerts and he said the Bryston's were as good or actually better than what he experienced with the major bands.

So there you have it; NO room correction needed, at least with these speakers.  My amps by the way are a pair of the Anthem Statement M1 monoblocks with dedicated 248 v/15 amp feeds running at 2000 watts per channel.  The T's love the power.

I gave room correction a try a while back. I bought a McIntosh MEN220, which I believe uses the Lyngdorf technology. I found that with my digital source, it worked nicely, but it sucked the life out of my analog source. I primarily listen to LP's, so the MEN220 is now gone. I must say that I have done a fair amount of work treating my room, and that is much more sonically satisfying for my taste.

Digitally corrected, fully time/phase coherent speakers in a room with acoustic treatment require minimal digital room correction.

My system uses two DEQX processors in a room with superchunk bass absorbers, speaker first reflection treatment (wall & ceiling) together with rear skyline diffusers. Slight digital eq is necessary only on two remaining wide Q bass peaks.
