Headphone distribution amplifier, Looking for suggestions Options

[doomsweek]

Hello, I want to power two headphones at the same time, an HD600 and an HD650. Currently I'm looking at the Behringer AMP800 and the PreSonus HP4. One of the problems I have with them is that they both have very big output impedances (47ohms and 51ohms, respectively).

Is it possible for the O2 to serve them both at the same time using a headphone splitter? But I think the HD650 would be louder than the HD600 for the same level. How do you guys propose I solve this?

You could also suggest different products. Budget is ~150USD. I want something that could power two headphones, has inaudible noise, has an output impedance of < 2ohm, and adds no coloration to the sound and has separate volume control for each headphone output.

Thank you and good day.

Is the Fiio E6 capable of raising the volume to comfortable listening levels for classical or music with really wide dynamic range for the HD600 and HD650?
