I am not against DIRAC. It does its job fairly well. Only thing that I thought was for OP to invest as much funds as possible for speakers without diverting funds for DIRAC from funds he/she can gather for speakers.
One can opt for DIRAC at later stage. It is more important to ensure that speakers have good components in crossover and speakers with quality crossover components come at a cost. The role of crossover is very important to ensure smooth sounding, better integrated and easy to listen speakers.... One which enables you to have emotional connection with songs.
This is what I have learnt in 2 years of my journey in hifi. Most of the components in my system are pre-owned as pre-owned stuff are available at considerable lower rate but at the same time you ensure that you are getting quality stuff.
