I don’t like what Lumin did ,they took away the external DC power supply ,Why !
because buy putting a good LPS on there Like a Teddy pardo for $475 brings the Lumin for close to their much more $$ unit .
the pardo is noticeably better then the SBooster ,but S booster does make a conversion for the D2 that is pretty good and much better then the smps in the stock unit.
