Experienced only: What have you done with room correction?

Erik,

  My experience with room correction via Velodyne SMS1 can be mostly a good thing if your subs and sats have a chance of being married. If there is no match with those to begin with, then it is same as being shot in the eye with a toothpick by some who say they are sorry but can hardly keep from laughing.

 OTOH, if I leave this task to myself, and a sub full of knobs, I will surely leave out something and not know the difference. 'Oh, there's deeper, fined tuned bass in this recording? I must have tweaked something to the left.'  

I’ve heard TacT (now Lyngdorf) completely transform a couple big $$$ systems to the point where you wouldn’t wanna listen to the system without their RC.  Avoid it at your own risk.  The ONLY reason I didn’t incorporate it into my system until now is because I was writing equipment reviews and couldn’t use it because it wasn’t appropriate for reviewing purposes.  Now that I’m free I’ll be all in for adding some kinda RC. 

I've been using a Velodyne SMS-1 with a pair of HGS-15s to augment KEF Reference 1s with excellent result.  I'm going to try a second SMS-1 in a stereo configuration in which L & R from the Ayre preamp will pass to separate SMS-1s.  RS-232 will connect the SMS-1s so only one needs to be addressed for settings to be applied to both.

I've been using Anthems ARC for several years (as a dealer and consumer) and as long as you have the expectation that its not a cure all to the system it is a great tool to use. Getting into the advanced adjustments allows for fine tuning to my ear on my system. I also use REW to measure the before to see what the in room response is. 

I've used 3 different REQ solutions in my A/V systems:  Dirac Live, Audyssey MultEQ XT32, and ARC Genesis. I consider them all effective, to varying degrees, with respect to reducing room colorations and providing a more convincing audio experience, at least to my ear.

However, REQ is intended to remediate only room anomalies. It is not a panacea for speaker or source aberrations. And I've always found further improvements to the sound are possible via manual adjustment downstream. YMMV
