How is the HA-2i. Interested to hear your opinion. Thanks

 
Hi !  
i am afraid i am not the most dependable of opinionists
However .... i would say nice sound.  I am using it with a k701. The sound is quite musical 
I do not have the specifications but i think the Z out is not very low. 
The sound is not particularly powerful but musical.  Nicely warm in the midrange.
I will try it with a 250 ohm Beyer and a 600 ohm Akg.; maybe they will be a better match. 
Lately i have come to the conclusion that maybe should be better to invest more in something above any suspicion.
Regards, gino
