All,
 
I want to move to high-end cans and want tod rive them with my pico. Wonder which limit I should get up to interms of impedance?
Knowing that I want to use my pico for more than 5 mins
 
txs for any advice

Higher impedance is actually easier for the amp & battery life (consider the result if you connected the output of the Pico to another amplifier -- likely 10K to 100K ohms).  You need to know the sensitivity of the headphone.  There are 120 ohm headphones that are significantly harder to drive than some 300 ohm headphones.
