AudioVero Acourate gives users more control over the results than Dirac. You can create your own filter curves to adjust any frequency as you wish. The bass issues mentioned above might be able to be adjusted in Acourate (to some extent, at least). The learning curve is steeper with Acourate, but in the end it is a much more powerful tool than Dirac. Trials are available for Acourate, as with Dirac I believe.
Yes, I have filters in place now for use with JRiver. They are rather mild in effect, by design, for the lower frequencies. When I switch the filters out the room nodes become too much.
Ideally room treatment is preferred, and make up any differences with DSP. In my case the listening area needs to serve as a "living room" as well, so room treatments are not so possible. Therefore, DSP.
I'll bet the people who say "stay away from it" are not users, but users would say the opposite.
