Maybe I'm going to have to sell this amp... I need to adjust the gain of my mp3 files and bring it down to 72db in order to get proper volume control with my ES5. And after having compared for a little while, the improvement is quite marginal from the ipod H/O that I'm starting to think that it's not worth it. Somebody at hydrogenaudio is calling me a "stupid hipster" for using portable amps for IEM's because this decreases fidelity and increases gain. Well I've seen many people using portable amps with IEM's on head-fi, so are we all stupid hipsters or what ?
Are you using an LOD?
