I do hope it is something that Devialet is seriously considering. My current rig is aging and not serviceable if something major fails and I've eyed Devialet as a potential replacement path. It would seem they have the processing power needed for implementation, any hesitation on the corporate end is probably related to the inherent difficulties/limitations in room measurement, coding a proper software interface and debugging it, and the tendency to endlessly tweak rather than listen. The latter in particular might be a disincentive for them since these units seem to be optimized for simplicity in operation, at least once initially configured.
I currently use a TacT Audio setup, it is digital throughout the signal chain. Input is PCM (optical, S/PDIF, or AES-EBU) up to 24/192. I use a modified Logitech Transporter as the source but just ordered an Aurender N10 to replace it. A TacT RCS2.2X is relegated to being a digital signal hub, measurement interface, and master volume control, all its processing is bypassed. The DSP is all performed in the four TacT S2150 amplifiers, each handles one driver group's crossovers, room/driver correction, target curve adjustment, and parametric EQ as well as time delay, phase, and gain matching in a horizontal quad-amp configuration; the specific filters for each amp are designed and programmed using (free) 3rd party TACS software. The outboard passive crossovers and electronic low pass sub crossover that came with my loudspeaker system are unused, rather the amps are directly connected to their corresponding driver groups. PCM>PWM conversion is performed at the final output with 150/300 watts into 8/4 ohm loads. Volume is controlled independently from the audio signal by reducing voltage on the output rails, so no loss of bits occurs. So basically, they are PowerDACs with variable output. The amps sounded excellent when new, and were further improved (substantially) by modifications including upgraded internal cabling, power supplies, and passive parts e.g. caps, inductors, and resistors... not surprising as they were built to a lower price point than the Devialet units. I have no doubt the Devialet amps would be significantly better.
Once one is accustomed to room/driver correction, there simply is no going back - physical room treatment can certainly help things in the reverberant range but does practically nothing in the modal range where all the bass problems occur. It is typical to see 20-30+ db swings over a few Hz in the low frequencies because of cancellation and augmentation effects determined by room dimensions, moving the speakers will change the frequencies of these nodes but not eliminate or significantly reduce them. Only with an infinite room - i.e. outdoor listening - do these issues vanish.
