Yes, used to have the Avantgarde Zero XD.
Ultimately, I felt that the DAC section in the XD was a limiting factor instead of the active speaker concept as a whole.
This article provides some insights on the benefits of active speakers:

Generally speaking, active speakers can be:
* active digital systems - included DAC, DSP, crossover and amplifiers
* active analog systems - included crossover and amplifiers
These can be built into one unit or externally (which somewhat negates part of the benefits of an active system).
I prefer the analog active system as that allows the option of upgrading the source, whether analog or digital.
Having said that, the digital active system does have more flexibility in that the built-in DSP allows for frequency, impulse, etc, as well as digital room correction in one package.
I have heard one of more highly regarded digital active systems, Grimm LS1be + LS1-dmf subwoofer:

An active speaker does lock one into the eco-system, and limits the options to tinker with the system. It would not appeal to those who like to upgrade or build systems.
The active speaker concept is promising and eliminates a bit of the trial and error in mixing and matching components.
It would be a major boost if there were more choices for analog active speakers in, say, the US25k - 50k range.
Sure, one would be locked in onto the amplifier + speaker cable + speaker interface chosen by the manufacturer, but that still leaves room to experiment with and upgrade the source components.
