How are you hearing no difference?

So you're saying that 'good' hearing is quantifiable among those who have it? 

Is this question serious ? 1st off Agon isn't going to allow any peer reviewed white papers to be posted that disprove 90% of audiophile snake oil , secondly who cares if people can't hear the difference between a $20,000 Audio Research amp and a $300 Behringer pro amp ,I wish I was in the camp who doesn't hear differences in components ,I'd sell off my entire collection ,replace it with a $500 Bose plastic mess and put an extra $100k back in my bank account , I've been gone for 8 years and still the questions are the same lol 

I think the questions are the same for a reason.............

I think this discussion is purely academic. By far, majority of people can tell the difference between a good sounding system and a great sounding one. It’s the so-called audiophiles that look for small incremental improvements which may or may not be apparent to an average person.

I think you are mistaken. I've never seen any indication that Audiogon limits content in the fashion you describe.

Of course, I'm not aware of any "peer reviewed white paper" that would disprove 90 percent of audiophile snakeoil.

Can you provide any evidence of either of these claims, bigjoe?
