How much power do the little and big egos put out for headphones?
32ohm
250ohm
600ohm
There's a whole page of specs but this is omitted.

Maximum Output Level: 1.8 VRMS (headphone); 2.1 VRMS (line)
Cheers

For those whose main subject wasn't engineering...... Because they're USB powered, and so run off a relatively low voltage, the Egos put out quite a bit of power into lower impedance phones (to a point), and less into very high impedance phones..... The Egos put out about 1.8 VRMS..... which works out to ABOUT (these are calculated and not measured):
100 mW into 32 Ohms 12 mW into 250 Ohms 5 mW into 600 Ohms Note that the efficiency of headphones varies wildly, and high-impedance phones tend to be very efficient, so be sure to take that into account.... For example, the 600 Ohm version of the Beyerdynamic DT880's is rated at 96 dB/mW - which would get you a maximum of about 105 dB with an Ego DAC. That would be loud enough for most people but, if you like your music really loud, the 250 Ohm version or the 32 Ohm version would be a better match. Some other brands and models are much more efficient. ) How much power do the little and big egos put out for headphones? 32ohm 250ohm 600ohm There's a whole page of specs but this is omitted. |

Keith the big ego has different amp specs right? |

The Big Emo has a line out at 2.1 VRMS that the Little Ego does not have at all. For headphone only they're pretty much the same. |

Thanks Keith. That's exactly what I was looking for. For those whose main subject wasn't engineering......
