The more "DSP corrections" that we add, the worse things get. In addition, DSP time alignment can only be useful for one seating position and distance from the speaker.

I would like to cover some misconceptions in here. The digital time delays are perfectly fine to do time aligning and it will not be for “one seating position and distance from the speaker”. If in this particular case, since vakman use DSP for LF crossover then he could easy to use his digital crossover time to deal with align his bass to his MF channel. He has analog filters for HF channel and to align that he needs to move his tweeter all the way back. The whole idea here is not to align the channels but to learn o confirm to himself that the channels are aligned and to discover how the aligned channels to affect the fine aspect of listening interaction.  The experiment might be well done at either digital or analog domains. 
 
The big subject however here is not digital vs analog aligning but slightly differently posed question: can the sonic problems that arrived from DSP filtering and an extra AD/DA conversion mask out the benefits of time alignment? He answers is yes and no. It all would be from the given experience of the given listener. An experience audio expert with well-trained ability to recognize the consequences of DSP and time misalignment will be able to extrapolate the result. If a person is not familiar with auditable benefits of time alignment, like in case of vakman for instance, then I would recommend to introduce one change a time and do not throw DSL and timing at the same bag at the same time.
