Yes, you'll want an amplifier with a low output impedance, especially since you're using a multi-BA IEM with crossovers, so make that your first criteria. And those are very sensitive, so you really don't want anything with a whole lot of power. To be honest, the only difference and amp should make is to stop the output impedance of the Classic from affecting the frequency response of the IEMs. Because the impedance of the IEMs is only referenced at a single point and can vary a lot, it's hard to tell how great this difference will be. It can be anything from subtle to quite significant. Personally, I use the Objective 2 with pretty much everything since it can do IEMs and full-size headphones very easily. If you're looking for something small, you'll want suggestions from another user. Maybe a Fiio E17 if you want something affordable? Fiio portables tend to have very low output impedance, so that's something to consider.
