hard drive mm can brake. It cant play 24 bit tracks?
In my opinion the iRiver H120 series is one of the best DAP ever produced and I really like the toggle remote, which is hard to find but I have two. But, it doesn't have the power nor the bloom to the sound of the DX100. It just doesn't compete. While the power is enough for most phones, you don't have the headroom of the DX100 and shear authority to the sound.
