I would suggest a total bithead or a fiio e7 for cheap amplifiers. I used a total bithead with my HF5's which are pretty similar to the ER4's and they increased the soundstage quite a bit and also enhanced the bass slightly. It also made the music a tiny bit heavier and less airy. I imagine the e7 with the bass enhance would synergize nicely with the ER4's as well. The built in DAC is very handy to have around as well, if you ever want to listen to nice music out of a laptop or a computer with a not so great sound card.
