I understand Eric. Dirac is becoming more and more available all the time. It's not available in NAD's receivers (some of which are priced very competitively) as well as Arcam (not so cheap but very good). Lexicon is also going to be offering Dirac on their newly launched receivers. I have Audyssey MultEQ XT in my system as well as Dirac through my laptop. I actually bought my receiver with Audyssey after having been a beta tester for Dirac Live. I was blown away by Dirac and wanted it in my system but at the time the only option for that was computer software. This wasn't convenient for me at the time. I bought the Onkyo thinking for sure that Audyssey would give me the same benefit. I was very disappointed in what I got by comparison. It wasn't just the house curve it applied, but also the overall effect. It wasn't that big an improvement over nothing. Dirac isn't perfect but it's by far my favorite room correction software right now. Enough so that I seek it out. It's the only corrective software I've used that can equal or better what I can do manually. Dennis can fix his problems with a new curve that provides that bombastic bass he seeks. I think Dennis has mentioned trouble creating new curves. That is one problem many people report. Dirac is not quite as simple to use as Audyssey and some have trouble getting curves loaded. I have even set up some of the NAD units for a local audio shop because of troubles they had. Dirac is working on this with the development of the new app and software updates.
