“This review is based on matching the Mini X with Hifiman He-500 Headphones. You may be reading this review, unsure what to make of this Amp, asking how can a cheap sub $200 amp offer the power needed for an expensive Headphone such as the Hifiman He-500? If you have done your homework you will find this is the stereo amp everybody is...” --fluidz
“This amplifier does an excellent job in powering headphones, and for the price, it could be the best out there for under $75 new. Other then power, the noise is not changed from original output. Hissing is present at some levels. Recommend to people looking for cheap power. ” --audiophilehe400

Previously, to have a clean output, I'd been using a FiiO E7...” --julian67
“ 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. In comparison to many times expensive amp unit, I could not pinpoint its weakness against. I think anyone cannot easily buy this performance per this price...” --Joong
“ Not much info about the SAP-4S on the web, this was a purchase I made mostly based on curiosity; there's only a single review about it in English that seemed pretty positive so I went for it. 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
