I'm just wondering if anyone has ever had like... problems buying from Ebay, I've always heard from family and friends to never even go to that website due to the amount of fakes out there... Most of all, I mean sorry to say this, but there are fake Beats floating all over. Wouldn't it be just as easy to fake "tube amps" or other headphones?
I have no clue about tube amps, but looking at that huge thread on "posting your head-fi gear" and people saying they get stuff off ebay leaves me skeptical.
How can you determine the authenticity beforehand? If possible?
