Mitch2, an acquaintance (who is in the "industry" and has had a ton of dacs through his system) recently acquired a $200 dac out of China called the WEILIANG DAC5 (http://www.ebay.com/itm/DAC-decoder-AK4399-WM8805-Coaxial-optical-input-Assembled-board-DAC9-by-weiliang-/1409397061030) and preferred it to the Metrum. I believe it uses an AKM chip.
