I agree that all modern DACs sound acceptable, but differences in

exist and will only show up on a DBT when the system used for the

performance. Otherwise, they go by unnoticed and leave the test
participants with the incorrect conclusion that everything sounds
the same.
Of course you have to partner the DAC with high-quality components for
any test. But without the DBT, the test participants will be left
with the incorrect conclusion that the units sound different. Better
still, your claim that some system has better "resolving power" can be
tested with a DBT. (With proper blinding, statistical controls, etc.
This should go without saying, but often needs to be repeated.)
Andrew.
Of course it can. But often it is not. My point was that if a system
doesn't show the differences between two components, then those
differences go unnoticed in a DBT.
Many here seem to think that it's all down to the specs of the DAC chips
(or modules) themselves. The power supplies and the analog stages
probably have just as much to do with a DAC's sound as does the D/A
converter itself.
