I'm planning to buy a hifiman he-400 but I need to see if I need another amp/dac or if the fiio e7 is fine...
Thanks

The Hifiman HE-400 is only 35-Ohms and I'm sure the E07 is decently able to drive 250-Ohm headphones.
Im driving them with an E17 and would not want any less power, if anything it needs more power to bring out the HE-400's best.
Drove my HE400s with E7s for a few months before I upgraded to E17, have to say, it drives it loud, but only barely, and at moderately loud volumes the E7 induces a bit of background static noise to the HE400 because it's being pushed so hard. Shell out another $40 and get the E17 if you are planning to get the HE400s.
What source(s) are you plugging the Hifiman HE-400 into?
