Last month, I got suggested to look Fidelio X1 as an option. After reading several reviews, I really liked what I saw but I'm still between the HD 600 (http://www.accessoryjack.com/sennheiser-hd600-open-dynamic-hifi-professional-headphones.html) and X1 (http :/ / www.amazon.com/Philips-X1-28-Over-Ear-Headphones/dp/B00B3QD94O).
Basically I'll use it at home mainly for music (Rock, Electronics, Metal, Jazz and Blues) and games. The amp I will use is a FiiO E17 (http://www.amazon.com/FIIO-E17-Alpen-Headphone-Amplifier/dp/B0070UFMOW).
I also heard that Fidelio X1 has problems with the cable impedance, if someone can suggest me a good replacement cable in case I end up buying it, I will be grateful.
Thanks in advance.
