Devialet D-premier, D250 and D200 has an active crossover feature via the configurator and that was a major reason for me to originally buy a D-premier. It can be used in different ways.
RCA 1&2 can be configured as an analog preout and that output can be filtered with 1st to 4th order high or low pass and the speaker output can be filtered correspondingly. I am using the low pass option with 2 monoblocks for my woofers see: http://devialetchat.com/showthread.php?tid=576
Alternatively on can use 2 D200 (=D400)or D250 (=D800) with digital connections. One amp can be configured for low pass and the other high pass. The second way to configure that setup is to have one amp left (one channel lowpass and the other high pass) and the 2nd right with the same settings (would allow short speaker cables). So the amps will be not used as mono amps with their improved specs but getting rid off the passive crossover (no matter what fancy Duelund etc. parts one has)will make a much more significant improvement in sound quality. I was tempted to trade-in my D-Premier to get a D200 pair but then I decided to go for the D250 upgrade.
That active cross over works quite well, the only feature I am missing is a time adjustment to better align woofers with the rest of the frequency spectrum. SAM has that feature but the use of SAM is excluded when using the crossover function. I guess Devialet has the knowhow to develop a time alignment functionality and I hope they will implement it as they promised 3 years ago.
