"Dcstep, a audio club recently did and discovered they could not hear any difference between items under test. Interesting comment by them-but what does it say?"
Well Psacanli, maybe there was no difference; however, some will say the test was flawed. I say that doing the test correctly is, indeed, difficult. I'll start another thread where I propose a methodology for repeatable DB testing, using 1-bit 5.6MHz sampling.
