Recently I came across a post in which someone said that his Fiio E07K was inadequate in powering his HE400i. By quick comparison of specifications, the HE400i, which has a rating of 93 dB SPL/mW and 35 Ohm requires ~5mW of power to get 100 dB SPL. The Fiio E07K outputs a maximum of 220mW at 32 Ohm which should be adequate to power them. However the poster said this...
"At full (12db) gain and at 80% volume, its still not bleeding levels and if the music is bassy, the amp distorts with each bass kick. You can hear it so clearly. I dont care about the measurements here. Im hearing distortion and each kick pound is like an industrial slop. And anyhow, by the time i increase the volume to that level the bass has already become so dry and thin."
Now I know that impedance mismatch can cause distortions but is there another reason that could distort the sound such as lack of current or voltage?
