Maybe we could introduce something like ´real´ test or ´o.r.v.´ test .
True. How about 'controlled test' versus 'uncontrolled test'?

For some reason, this time, I think I get your point.

Seems to be the same problem with ´controlled´ .
Maybe orv (for o bjective, r eliable, v alid ) ?

@ SY,

you should consult Athena in all of her virtues from time to time.

Folks, our car is "off the road on the shoulder..." Let's all recall that the discussion ought to relate somehow back to the topic...

I do not think that we are going to wring out the final drop of insight regarding the good or bad of a "DBT" (ABX or not)... not any time soon.

Suggest we move on...

OTOH, 'controlled' clearly shows the intention of the test. ORV does also, but I doubt that that will catch on widely.

You are right bear. What will come out of that test will be that all competently designed
electronics sound the same. So let´s make our products cheaper and smaller as Peter Walker was sugesting.

@ janneman,

´controlled´ is necessary but not sufficient while ´orv´ is comprehensive.

Of course, you´re right ´orv´ will most likely not suceed.
Maybe something like ´competent´ or ´qualified´ could serve.

An objective, reliable and valid test would most probably bring a positive result (rejection of the null hypothesis) if a difference is audible (at least to one listener on earth)

Can someone recommend specific source components that are best with a Blowtorch?
