hi, i currently have a AD700, and have a HD 598 on the way. both of these headphones don't necessarily need amp, except for 598 might benefit some during heavy bass punch.
but since i've been thinking of either getting a Fiio E17, or a Asus Xonar Essence STX. both are about the same price on amazon currently. i know they're not apple to apple. but since i eventually will probably end up getting both, just the matter of which one to get first.
i want to know which of the two will have the better audio quality. what kind of DAC/AMP do both of these hardware use. i know that the STX uses Burr Brown DAC, but that's about all i know.
like i said i will probably end up getting both in the long run, but if one is better sound quality, then i might get that first.
