Your distaste for the kind of DBT that professionals use is well known.

That's only because it seems to often yield little useful information.

That would probably be due to differences in one's definition of "useful
information"

For instance, two DAC units that sound identical in a bias controlled
DBT, when connected to another system with more resolving power clearly
showed that one had much better and tighter bass than the other.

Perfect example of faulting DBT procedures when the problem might have been
at a higher level - the choice of system used for the evaluation.

Apparently someone has been reading a book where it is written in stone that
DBTs can only be done in inadequate systems, and more specifically never the
system at hand. ;-)

Furthermore, there is no evidence that the test in the second system was
bias-controlled, so we appear to have a surreptitious raising of the
perceived merit of a sighted evaluation over the DBT.

In short, I see evidence of overwhelming false logic, bias and denial in the
above comments.

The DBT
didn't show that because the system used didn't have great bass itself.

Not at all the fault of the DBT, yet it is apparently being presented here
as a global limitation of DBTs.

In another similar test of DAC units, two otherwise identical sounding
DACs yielded very different soundstage and imaging results when
connected to a system that imaged well.

Same mistake, just different systems and different related system parameter.
