It is hardly the dealer fault.
Of course it is. Look at Beyerdynamics. Americans (with prices in USD) get better prices on Beyerdynamics headphones than even Europeans do. Same goes for AKG, both manufacturers are in Europe. I've seen speakers made in France sell new in the USA for LESS than what they sell new in France.
Dealers get preferential prices on gear they order to sell in their stores. Ours are just greedier.
For comparison's sake, taking amazon:
French amazon, Beyer T1: 700 euros (960usd)
http://www.amazon.fr/Beyerdynamic-T1-Casque-audio-HiFi-Stereo/dp/B0031RD3YY/ref=sr_1_1?ie=UTF8&qid=1399283063&sr=8-1&keywords=beyerdynamic+t1
US Amazon, Beyer T1: 900usd
http://www.amazon.com/Beyerdynamic-T1-Audiofile-Stereo-Headphone/dp/B0031RD3YY/ref=sr_1_1?ie=UTF8&qid=1399283080&sr=8-1&keywords=beyerdynamic+t1
French amazon, AKG K712: 400 euros (550usd)
http://www.amazon.fr/AKG-K712PRO-Casque-Monitoring-Professionnel/dp/B00DCXWXEI/ref=sr_1_1?ie=UTF8&qid=1399283168&sr=8-1&keywords=akg+k712
US amazon, AKG K712: 380 usd
http://www.amazon.com/AKG-Pro-Audio-K712PRO-Headphones/dp/B00E4WXWBE/ref=sr_1_1?ie=UTF8&qid=1399283174&sr=8-1&keywords=akg+k712
Beyers are made in Germany, AKG in Austria. Explain how Americans get European products cheaper than Europeans do, and Europeans get American products (such as Grado, Audeze to name a couple) at a 30% mark-up minimum?
I would save big time ordering the K712 on amazon US even with shipping + taxes, when the headphones are made in Austria.
