Using preamps with Bass Management and Room Correction?

I am curious to see if anyone is using a preamp (Like Anther STR) in place of an all analog 2 channel preamp for their 2 channel system and their opinions on both the bass management aspect and room correction. Was moving from an all analog preamp a sideways move, an improvement, or a step backward? Similarly curious of people’s experiences using JL Audio bass mangement or Minidsp. Specifically I am curious if the benefits of bass management and room correction supercede the benefits of an expensive all analog preamp(ie:Audio Research Ref 6) in your opinion.
