Benefitting from NOS DAC design, HM-601 is a warm, natural and musical sounding player. HM-601 has very similar sound to HM-602 because these two players share same D/A converter and headphone amplifier circuit. HM-601 has slightly better bass extension than HM-602, and a little less sweetness and smooth texture in mid and high (A lot of people might not be able to tell difference at all). As the simplified version of HM-602, HM-601 can not work as a soundcard, and using different op-amps. HM-601 has 2Gb memory, which is much smaller than HM-602's 16Gb memory. With the high / low Gain switch, HM-601 can drive both high efficiency IEM and most full size headphones.
