DUDE! I went there to test OPN, the office near Budapest...damn, that was such a funny experience...this women was the height of unprofessionalism :)) I am not even sure if OPN just did not work for me, if it was badly calibrated or what because I don't trust her but to me, it felt a bit "off". I am kind of sorry as I read so many good things about OPN...
At the end I was like: So what's the next step if I want to buy them? And she said...this still cracks me up..
"Pai, vino cu malaiul!" : ))
Damn, I got to say Audionova is expensive and pretentious but at least they are professional.
As for the Widex people..don't get me started, that Ioan Mares or whatever his name is was so haughty and patronizing. I did not even get to the test...as I said,I'm sporting a Linx 3d now which was insanely expensive anyway.
