This headphone amplifier receives a perfect five out of five star rating from Techradar for its excellent sound quality.

"Maximum output is impressive into low impedances, with the ability to drive nearly half a watt into 15 ohms. The distortion rises, but that hardly matters because your ears will have overloaded long ago! Under more sensible conditions, distortion is as low as any. Output impedance is quite low at 6 ohms, which should ensure consistent operation into any normal headphone load. Although the basic component count doesn't immediately look like twice the value of the others in this test, sound quality does seem to justify the outlay as this is clearly an exceptionally capable device."
