HIFIMAN Supermini High-Res Portable Player

Download latest firmware: http://www.hifiman.com/services We spent years on a crazy project: SuperMini. We selected a low power consumption controller chip with a DAC built-in. After heavily modifying firmware and drivers of decoding/Audio/DAC, we have changed its original sound signature and achieved an amazing result: a sound signature similar to our flagship hi-fi music player HM901. That is why SuperMini sounds transparent, warm, sweet and punchy. It is one of the smallest portable hi-fi devices. Its battery life is 22hrs. Full Size headphones? Not even a challenge The swing of output voltage is 4.2V peak to peak, capable of driving most full size headphones The output power can reach 320mW which can perfectly drive the HIFIMAN HE400i and HE400S planar magnetic headphones. Thanks to the power saving design, the SuperMini is built with 8 op-amps and it can reach output 4.2V @ 32Ohms. That is powerful enough to drive most headphones on market.
