Hifiman HIFIMAN HM601

Checkout the Hifiman DM601 which is the cheapest version of Hifiman's portable audio player. The sound quality is said to be superb and there is a powerful internal amp within which explain why its rather bulky. But it means it's capable of driving demanding headphones and earphones without having to use an external amp. It can be bought for 259 $ with the great sounding IEM RE0 from Head-Direct
