I'm going to buy the hd598sr (mainly for gaming purposes) and really need an external dac amp combo for it. I'm going to be using it for my laptop (lenovo y500) which doesn't have a good mobo and so I was thinking of getting maybe the fiio e10k (haven't done much research) to get the full use out of these. The cheaper the better as always and I would like the best experience I could get for gaming out of these. What would you suggest?
I have a little Fiio Q1 for portable use. It's pretty good for the price. I mostly use it with IEMs but it drives my HD 600s and HD 650s just fine when connected to a computer or laptop via USB. It most certainly would drive HD 598s. The E10K would also be a great choice.
