No one knows - it's not printed anywhere in the official literature nor in any review - and hence the point I've been making. Since there is a trend for speaker gear manufacturers to overlook this, and in many cases even when they make headphone amps and state the output impedance it's still usually a bit high (MF V90HPA is rated at 50ohms), it's safer to assume the output impedance is on the high side rather than low. You can risk it if you want to of course since it's your money, but as far as recommendations go, the safer bet is to assume it is likely higher than desirable.

I sent an email to Music Hall asking output impedance:

"I can not find it anywhere output impedance.
I do not know if it's better headphone low or high impedance."

 
"It will work well with headphones between 30 - 600 Ohms."

I still do not know the output impedance but I have noticed that the output gain is very high and the Fidelio x2 (32 ohm and high sensitivity) the answer is not very good.No can turn up the volume more than 1/3.
I tried several high-impedance headphones and all seems right.(hd650,Akg K601)
