Who is using Dirac?

Like most others, I have been trying to squeeze perfect soundstage, imaging and detail out of my system. And like many others, I'm battling WAF ("why do the speakers have to be so far into the room?"), furniture, etc.. I'm reasonably happy with my system which is a Mac 352, C2300 (Gold Lion tubes), Dynaudio C1s and Clear Day cables. Using as my source a PC based system running thru Wyred4Sound DAC 2.

Just downloaded free trial of DIRAC and went thru the Mic calibration set up. I wont go into the hours of trying to figure out drivers etc. which has been posted here by others. I was however, a bit disappointed with the results. The delay and gain was OK (a minor improvement in balance)but the filters for optimization sucked the life out of the presentation.

I suspect with a lot of time investment I can get this to work to some level of satisfaction but in the end I also suspect the results will be a minimal improvement. Finally wondering if all of this is worth the purchase price.

Thoughts/experience from others? Thanks in advance!
