Have been using Dspeaker Dual Core Antimode 2.0 since 2012.
Very easy to use for basic room correction and it has lots of additional functionality besides. Terrific customer support if you have a software issue like when doing uploads of new versions.
Two downsides. Wall wort power supply is a little veiled and should be replaced by an LPS if you want the last word in transparency or just use it on the subs (you can EQ but you won't have a completely time aligned system then). The postage stamp screen doesn't have the resolution you need if you want to do extensive frequency tailoring. These will not be drawbacks for many people. I use mine with REW & a laptop to get around the screen resolution issue, but that's complicated and my system if far from typical..
Another totally different and great option is MiniDSP.
