It is well known that Non-oversampling dacs offer great sound for little money. HM-602 is the first portable player using non-oversampling DAC: Philips TDA-1543. As younger brother of HM-801,  HM-602 shares HM-801's great sound signature. To make it as portable as possible, HM-602 do not have amplifier modular design. However, its headphone amp part is very similar to HM-801's standard module. To drive both high impedance and low impedance headphones, HM-602 with the high / low Gain switch can drive both high efficiency IEM and most full size headphones.  In addition, HM-602 also can work as a USB DAC.
