The reason why Buchardt does not add Bass management, because that would interfere with there room correction and they are of the opinion their speakers go deep enough.
If true, the first reason sounds like a drawing board problem. As in, the approach is irreparably flawed, so back to the drawing board.
If true, the second reason broadcasts ignorance of modern high fidelity audio system design. Yes, for a single listening position a pair of speakers with sufficient LF extension and volume displacement can be EQ'ed to sound very good. Add more than one listening position, and everything falls apart. IMO, "lifestyle systems" miss the point if they lock you down.
If you are talking about progress, this is progress and it brings HiFi sound to normal homes and interiors as all in one solution.
Expensive but hamstrung is not "progress" by any measure, when there are much cheaper products (here, ELAC and MartinLogan integrated DAC amps with bass management and room correction for ~500 USD) with the necessary feature set.
Different products for different customers, not one being better than the other, simply different.
An integrated amp or preamp with flexible bass management is definitely better than a hamstrung one.
Your assumption here is just because basic features are present, they must be used. Bass management can be turned off for a 2.0 channel system. If this necessary feature was omitted at the design stage, however, it can never be turned on.
