Them BF1 videos have me sold I think, £189 on the rain forest, will run it with my HD555's for till I get my 599's for xmas.
The problem I have is the HD599's and GSX are going to cost £390 together, a STX II and HD650 will cost me £440. Which would be the better gaming setup bar £50.
GSX no doubt. For the HD650 + STXII to be the better gaming set up of the two, too much hangs on you liking Dolby Headphone. If you don't like it, as shankly and others do not, then just as a gaming set up, it would be a poor choice in my opinion.
The HD555 are rated 120ohm and the 599's 50ohm will they be ok?
Yep, no problem. Despite being 120 Ohm, the HD555 are efficient headphones. Easy to drive and that's what's needed with the GSX.
Without detailed specs, Ohm rating is really not enough to go on. That's why when this was announced with 150 Ohm rating, people questioned if it could power the HD650 properly. If you look at the Ohm rating, you assume no, but the FiiO E10K is also 150 Ohm rated, and can drive the HD650 surprisingly well. The GSX as it turns out, cannot.
HD555 are 120 Ohm but are efficient and easy to drive. AKG K701/2 are 62 Ohm, but are insensitive so need more power than most headphones of similar rating. K701/2 despite having half the Ohm rating that of the GSX, it would not drive them properly.
Some manufacturers give very little detail, so it becomes trial and error, until word gets around what headphones work well with what.
Thanks, I really don't get how all this works, my SB-Z and HD555 I can only use up to 20% volume before I become deaf.
HD555 being efficient and the Soundblaster Z having too high a gain output are the reason. Creative should have put a gain setting on the Z/Zx, like they did on the ZxR, and like Asus did on even their cheapest card. Gain setting allows people to use low Ohm sensitive headphones without being deafened.
Why Creative did that, I have no idea. They do odd things from time to time.
