“This review is based on matching the Mini X with Hifiman He-500 Headphones.

“ I didn't expect this little Chines guy to generate impressive sound. When it is pairing with DT990 - 600 ohm, Cello concerto of Britten superised me of its crisp sound and wide soound stage with enough volume.

Packaging is a nice little white box with relevant logos. When opened you're greeted by various neat accessories like a flat usb charging cable, protective leather case, silicon band, and well made 1/8"...” --kidcharlemagne
“ This is my first amp so bear with me lol. I bought this from ebay with minimal fuss and didn't have to wait long. I quickly plugged it in and had a listen, first thing I noticed was the audio sounded weird, soon worked out the RCA inputs are marked wrong, even the colours are wrong but not a serious problem just a quick switch around (the 3.5mm input is fine). The second...” --cokker
