The problem with absorption panels- it kills the fine details

Hire a professional to measure your room and make specific recommendations or, get a semi professional measurement job done with the help of GIK or another of the many vendors who serve this space.

Room correction programs like Dirac or similar help a room to suck less, not sound better. It is also unlikely to be of any use EVER to someone with an analog setup.

It isn't hard to achieve the desired result but it isn't inexpensive to do it correctly.

A little anecdote. My local retailer sells megabuck equipment. Over the years, I have auditioned Wilson, Gryphon, Spectral, Rockport, etc. Many systems approach $100K. I have never once been engaged by any of their systems. The culprit was an acoustically dead room. Recently, a friend got the audiophile bug, and we auditioned a system for him consisting of KEF LS 50 Metas and a Primaluna integrated. The dealer's room was minimally damped, but the sound was some of the most engaging "toe-tapping" sounds I have heard. I would have easily guessed at least a $50K system if I was blindfolded. That dealer's philosophy is to replicate a customer's listening room, which they do an excellent job of. 

Measure your room...hmm...how about simply listening to your system? Move the speakers...never rely on the opinions of anybody else as your earballs are attached to your head. My speakers are horns and my sweet spot  for critical or optimal listening is around 8 or 9 feet from the speakers...interestingly, further out in the room (long room with 18' ceilings, huge stone fireplace along one wall, huge euro style windows...blah blah) it sounds like real musicians are playing from one end, and that also sounds great. I thought when we bought the place a couple of years ago, that room would be Horribilus El Reflecto...it's not, sounds great. A great live music room also...who knew? 

Of course every room is different with different needs. It seems to me that reflections will alter the sound you were supposed to hear as mentioned above. Not wanting to play the guessing game I had my room designed by a professional and I built it. It is virtually all absorption on every wall and ceiling. There is no drywall in the room. It is definitely considered a dead room and I was nervous about how it would sound. After everything got broken in I was blown away by how good it sounds. I hear mostly the direct sound from the speakers and I don’t feel I’m missing anything. I have been fortunate to have a few members with more experienced ears over for a listen and I believe they were pleasantly surprised how good it sounded. If anyone else here would like to come over for some listening I’d be glad to have you. 

So I’d say and over damped room is better than an under damped room. Happy listening!

My above opinion is mostly in regards to smaller rooms where the challenges are greater.
