I apologize for starting this thread if there is somewhere else that this question is clearly answered, but to be honest, I've been searching and searching and have found very few posts on this topic that offer much in the way of detail. With Low-impedance, high-sensitivity IEMs how much difference does an amp really make? I'm not looking for "it depends," I'm looking for people's actual A/B stories. The posts I've found have been divided between "not necessary, don't bother" on the one hand, and "yes, EVERYTHING sounds better with a good amp" on the other. But the people saying the later are often mainly talking about full sized cans, not IEMs. And many amps reportedly even make the IEMs sound worse, because they're way too powerful and end up generating more noise than clarifying the original signal. I can't find any consensus on this. Everyone seems to always be talking about full sized cans. But I have turned exclusively to IEMs, and I prefer the sound signature of the UE series. Am pondering eventually getting the UE-11 or the JH-13. I would love to know from the OLD TIMERS on this group, the ones with lots of experience listening to many different amps, sources, and IEMs, how much difference in sound quality the amp made, and what were the best amps for the money for these kind of IEMs in their experience. If you have a portable rig that uses an low-impedance IEM and an amp, I want to hear about what you've tried and what you think faired best and why. are there any cheap amps that work wonders? any mid-range amps that made a huge difference? are there any amps TO AVOID using high-sensitivity IEMS - one's that will make them sound WORSE? I want to know. Thanks!
