Poor assumption. It was at a show so I could do neither of those things. I will point out that I heard almost no difference where I wanted to hear one (AK100ii to AK300) and significant difference where I wanted to hear none (AK300 to AK320). And as I said, I will be doing a full review when I get my review units and I'll be testing a lot more rigorously than one can in a show environment.
Feel free to draw your own conclusions about the validity of my tests vs the guy who couldn't hear a difference. As always, the best test is using your own ears. Barring that, you'll just have to wait for more people to test and see what kind of consensus develops.
The only reason I reiterated my point is because I hate reading statements that are so obviously confirmation bias:
This person disregarded my testing completely as soon as a single person said what s/he wanted to hear. At that point, why even read reviews? Just get what you had your mind set on to begin with.
