Digital Room Correction For Speakers

Thanks for the great review. I need to look into this system.

There´s also Trinnov in that price range.

One thing I believe is that active room correction actually means different speakers can compete in the same room on a more even basis. You hear that the difference between speakers after correction is actually less than before, which means the room interaction on different speaker accounts for the main difference in sound. You can now concentrate on dynamics, resolution, tonal qualities, edgeness etc that is left.

Can the DSpeaker X4, be used strictly for room equalization and not as a preamp or dac?

The Anti-mode 2.0 can. Surely also the X4. But the 2.0 has enough possibilities to make you occupied until summer! What the 2.0 miss and the X4 has is a xo bass management system. I use a Lyngdorf RP-1 or 2200 amp for this.
