hi, 
i've searched but not been able to find anything of use on this amp from opera audio.  just wondering if anyone has any experience with it, it has a wireless DAC and dedicated headphone amp.
i'm asking because someone is selling one in my city for less than 50% of MSRP
 
here's the stats if they help, is this worth $400?
