I had some Klipsch LaScala's that i tried DSP, mainly for time alignment and better control of the bass cabinet. worked well but in the end, I preferred a newer designed passive crossover, it just sounded more naturel to me. Granted you miss out on some of the DSP functions and lose a bit of bass control and integration.
Note at the time i listened to vinyl primarily so that was a consideration, having to digitize the signal seemed to lose something in the musical side even with the benefits of the better driver integration. Potentially a better DPS then the one i used would help here.
lastely i would not use your ear for adjustment ( other then minor) if your going to digitize it anyway may as well use proper messurments and adjust to the room. Thats the biggest advantage of DSP IMO
