Best USB port on Mac Mini ?

[Ralf11]

can I convince you to try a device in between your computer and your DAC that provides galvanic isolation?

 

use something you can return if your DAC doesn't "need" it

[Ralf11]

Then you should be fine.  Use the most convenient USB port, tho it won't hurt to use one 'distant' from Bluetooth.

 

Time/$$ put into noise isolation for the DAC will likely be more worthwhile.  Acoustics will likely be much more worthwhile. 

[Ralf11]

what DAC?  and any other devices in the chain?

[Ralf11]

or maybe because the "test" results are meaningless due to lack of controls

 

or... lack of statistical validity

 

or... the "subtle" differences (if any) escaped you 

 

 

[Ralf11]

No, a control in an experiment is not a measurement.

 

Perceptions are highly variable.  If you will buy a good bottle of Scotch I will administer some to you at your next listening session, as a test.

I do not drink alcohol. If perceptions are highly variable (and they are) there is no reason to look for "better" port or "better" type of connection – perception will necessarily adapt to any.

 

there is a logical error in the above

 

variability in X does not mean that there will be accomodation to the best Xi

 

I suggest avoiding a discussion of adaptation here

[Ralf11]

same error
