Although if already an analogue signal, you don’t want to really convert back into digital again, take the discrete data stream through some sort of convolution process and then convert back to digital... you are starting to throw info away by doing this... you can look at it a bit like going through lossy transcoding. Converting between analogue to discrete and from discrete back to analogue is necessarily a compromise and lossy in the limit..
Is this (at least some of) what Devialet does?
Well I believe Devialet is all digital from the moment any input enters the unit via ADC on analogue inputs. Linn operate the same way these days.
The difference being that you can buy a Linn Exakt box that takes an analogue input instead of a digital one if I am not mistaken. And that goes down the ADC > crossover > DAC aporoch that I am similarly suspicious of.
The Bryston analogue crossover sems like the best approach giving the right balance of flexibility whilst making it difficult for the user to drunkenly destroy a pair of speakers. They have two models. One with dial set crossover points on the fascia and another without that where the user orders plug in resister boards. The exoectation on the latter being the speaker manufacturer tells you which boards to order. The fascia just has slope and output levels but no crossover points. It operates stereo 2-way or mono 3-way.
In my opinion, this is the approach for Naim to emulate with a future SNAXO.
