FiiO X7 High-Res Smart Audio Player (X7)

FiiO X7 Android-Based Smart Portable High Resolution Audio Player (X7)

The FiiO X7 was designed originally for hi-end audio, the X7 is one of the first devices to utilize the original ESS ES9018S in portable audio. Its 8 output channels can be bridged 4-a-side for an astonishing 135dB S/N ratio and dynamic range, while THD is as low as -120dB. Compared to the ES9018K2M popularly used in portable devices, the original ES9018S features 6db higher SNR and dynamic range at the cost of higher power consumption, a cost that the X7 is willing to pay with its robust power section.

Given the unavoidable thickness of the X7 from having a flagship class DAC, amp and a battery to match, making the X7 comfortable handhold-able from a thickness point of view is also significant challenge.
