The result [in the 6-channel Milq] is definably better but the reason-consequences patterns are not so easily interpretable, and are absolutely not interpretable when the filters are applied.
And the explorations that led you from the original Melquiades to this current set-up are well-documented over a period on months.  Still, it might be instructive (to me at least) to hear concisely stated your dissatisfactions with the original set-up that led you to make the changes.

Well, I understand the objectives and you are right in them but the experiment will not take place as I am already out of the league of the methodological correctness. You see, the 6-chennal of Super Milq is betraying of the DSET idea as the new Super Milq uses one-stage amps ... so, the Super Milq is not the best illustration of the DSET concept. Also, the Super Milq-type of amps are possible only in context of targeted binding to a specific acoustic system/room.
This is true, but it reflects also quite accurately my own situation.  I have the EdgarHorn Titans and no intention of building new horns anytime soon.  However, I am buying up the parts to make the Melqiades amplifier.  My own personal question is whether I should proceed as planned or instead build up DSET versions to drive the four channels of the Titans separately.  I am not keen on building original Melquiades "just as an experiment to compare to DSET I will build afterwards" either because it will end up being a lot of money and time, and I am kind of in the situation where DSET might be appropriate.  However, I ask the advice of someone who has already done this whether it is worthwhile in my situation (this is the argument of course for DSET in general as well).

The problem that a regular SET has might be addressed by 2 channels - where one cares LF and another rest of the spectra. THAT is my primary definition of DSET. That DSET is very easily implementable and marketable commercially. We are accustomed in High-End that the speakers are bi-ampable and that the cables are bi-wireable. Why a DSET should not feel the gap where it could. A DSET should not even care a crossover – most of “better” speakers allow bi-amping and their driver-level crossovers are bridged externally… The DSET would be a perfect match in there.
 I think it may be difficult since the crossover points vary and some speakers can be even triamped.  This is a rarified market already.  Most people planning to bi-amp, they are told to use the identical amps to do so, so this will build resisitance to the idea of using different amps.  Also, it is easier and cheaper to buy one more amp (or pair of monoblocks) identical to the one you already have than to buy four new monoblocks.

So really the target market demographic is audiophiles who are already bi-amping but who can be convinced that they should be bi-amping with DSETs instead of the paradigm of using the same amps, and whose speaker crossover points fit with the design parameters of the DSETs, AND whose ears and systems can appreciate the relatively subtle changes of going from biamp SET to DSET.  I am going to be honest, I think this is going to be a really small number of people.
