Z Review - Schiit Fulla (Micro Dac+Amp) (MADE IN THE USA) (!!!)
Currently only available on their own site [http://schiit.com/products/fulla] the fulla competes with the likes of the FiiO E10K [http://amzn.to/1AmMTcV] and the SMSL M2 [http://amzn.to/1sDDtux]. Both alternatives have more options but both are bigger and not made in the U.S.A.
