Is the Fiio E6 good enough for the HD 598?

post #1 of 5

Well, is the newly released Fiio E6 able to juice the HD 598? I think it's possible given that the HD 598 has quite a low ohm.

At 50 ohm impedance and 108 sensitivity, we'd only need like 1.5mW of power to get over 110 SPL. The E6 can output ~1.2-1.3v, which would result in 31.25 mW of power.

 

Basically, you'd have way more than enough power.

The sensitivity of 108 dB is for 1 Vrms, rather than 1 mW, but the 1.2-1.3V is probably enough anyway if you do not want very loud sound. For the HD598, it is important however that the source should have a low output resistance, since the headphones have a large resonant peak around 90 Hz (reaching almost 300 Ohm) in the impedance curve.

Luckily, assuming the E6 has similar tech to the E5, the output impedance should be definitely low enough.

my ety er4s have 100 ohms and i cant turn my e6 more than half way before its too loud. you'll be fine, its a good little amp.
