Hi,
 
I have Sextettes which have 600Ohm indepencence max 200mW. Is something like Asus Xonar Essence STU amp/dac
which has 80mW @ 600ohm enough for cans like these ?

It should be no problem for the Essence STU to drive the AKG K240 600-Ohm headphones.
My Essence STX uses the same TI6120A2 head amp chip as the Essence STU and has no problem driving my AKG K240 Monitor 600-Ohm headphones.
 
But skip the Essence STU and get the Audio-GD NFB-15.32 external DAC/amp, $255+shipping.

Dual DAC chips and a more powerful headphone amplifier.
I've been using the 15.32 for three weeks, it's taking over from my Essence STX.

Does Audio GD stuff work under windows 8 properly?

Seems that they are as the page states that has drivers for W8. 
 
I cannot get them directly from their homepage so I have to use reseller and was looking at polish reseller stock. They only have nfb-11.32 (with sabre ES9018 chip) and nfb-5.32 (dual WM8741 chips). Which one should I pick and why ?
