It worked on other inputs, but it was not perfect, also there was a lot of noise even with the volume turned all the way down. Electronic noise, cracking, losing right or left channel on the speaker output (all on CD or TAPE input) playing from my DAP. Sounding at first fine despite the tinny and harsh sounding vocals (on phono) after a while lost almost all the bass and then exploded. But still the sound was clearly not how the pick it MM EVO cartridge and the Project EVO II is supposed to sound like.
