HiFiMan HM601

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 8Gb 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.

Здравствуйте.
Сейчас на вашем сайте исчез из продажи плейер Hifiman HM-601, но зато появился Hifiman HM-603. В описании ничего не поменялось кроме цифирок в названии. ЦАП, если я не ошибаюсь, тот же. Так что же это за чудо такое Hifiman HM-603? Модифицированный 601? Я так понимаю, если цифры разные, значит новая модель. А в чем разница с 601? Расскажите пожалуйста.
