Xduoo is a new company in audiophile market and judging by reviews they aren't bad for being a fresher. Their current offerings are some portable DACs/amps (XD-01, XP-1 and UA-05) that has already been released and has received quite good impressions. According to their website they have a high-end DAP , X3-B under production (wonder whats with the tag X3 and Chinese DAPs, we do know fiio X3) Now there i had to use google translator, figured its in Chinese from those cross-arc signs Using patented technology: ZL 2010 2 0214978.5 Supports MP3, WMA, WAV, APE, FLAC, OGG, AAC and other audio files. Capacitive touch screen, Dual WM8740. Headphone amplifier uses opa627 + buf634u. CNC aluminum shell, Little thick but looks cool, the potentiometer looks little similar to hifimans flagship. From the looks and specs saying cnc Al shell, i guess its sturdy. Their is no speculation regarding run time and release date. I 'll update this post with further details.
