HiFime 9018 Asynchronous High resolution USB DAC, DSD playback, 384khz/32bit

In the Hifime 9018 dac we have managed to fit the high resolution, audiophile Sabre ES9018K2M DAC chip in a tiny compact box, the same used in our U2 and UAE23 Sabre dac's. We used a double PCB to be able to fit in this small box. This chip has great specs like 127dB DNR, -120dB THD+N and patented Time Domain Jitter Eliminator. The USB receiver is the Savitech SA9227 USB used in asynchronous mode. It supports all sample rates up to 384Khz/32 bit and are clocked by two onboard oscillators. Hifime 9018 has MAX97220A headphone chip that can drive headphones down to 16 ohm as well as higher impedance headphones as the Sennheiser HD650. The volume level goes quite loud, more than enough for 300ohm HD650's. It works without drivers in Mac, Linux, and requires drivers to be installed in Windows. Note that 384khz only works with ASIO which is accepted by some programs only, and not by Chrome, Youtube etc. Chrome on Mac's also doesn't support 384kHz. It uses by default USB Audio Class 2 which is required for sample rates above 96kHz. It will switch down to Class 1 if USB High speed mode is not available.  It also have (like the U2 and UAE23) an optical output, which works up to 192khz. In addition to normal PCB format It can play DSD files. We think the sound of this DAC is really great! Another cool features is that it works with Android 5.0! This makes it a super small portable highly audiophile solution. Only caveat with phones is that it draws much more power than our smaller Android dac. The Nexus 6 battery lasts for 6 hours when playing constantly with the 9018 dac.
