China's Musiland has gained quite a following especially in the headphone enthusiast circles. Its MD10 is considered one of the best in terms of price/performance ratio. Its new DAC/Headphone amp, the MD30 features USB2.0 high speed asynchronous interface at up to 32bit/192kHz. At its core, a FPGA audio processing technology promise lower jitter and more accurate sound. Also new is an asynchronous high-speed cache and DDS re-clocking scheme via is 1ps high precision programmable clock. Its headphone section features "Energy Headphone Amp Level-III" technology provides a comprehensive headphone drive capability than competitors.
