Yes, I'm going to use portable amplifier, and I searched over internet and lets be honest, Fiio E07K and E17 are the most recommended models,
You mentioned that I may find only amplifier which will be suitable for me in the portability point of view.
Could you recommend the amplifier models for my HD 598, which will be able to show me the full power of my cans?
Also, I have red the articles on this site in which the users say that amplifier is needed in case of audiophile headphones too, in order to come headphones more close to life.
They recommend mainly Fiio E07K or E17 and I saw the comparation of these models in official site. the sound quality is almost the same, especially for such a level of impedance which HD 598 has (50 ohm). I mean, E07K is recommended for headphones with 16~150Ω impedance. That's way I think that E07K will easily handle HD 598 and show its full sound.
I will use my HD 598 for listening music through my Iphone.
so, I think support of 24 bit / 96 Khz is also not useful for me.
But the sound quality is the most important thing for me. That's way I decided to buy E07K or E17.
I've seen also Fiio E6 which is also high rated amplifier at amazon.com. But I'm not sure that with this model HD 598 will show its full potential.
I may wait a short time, hear the recommendations about my choice :).
