Negative Positive
Title: Worked for me
Review: I wanted something to boost the line level output of my mp3 player in the car. I got a Fiio unit which was very nice BUT the problem was that it has a soft power button so needed to be turned on every time. I wanted something that could be buried and just come on with the ignition. This unit has a regular on / off switch and the boost is enough to make the line level much much better. Clean sound too.
Is the review positive or negative?
