• Throughout design and production process, numerous tests were done with advanced lab equipment to ensure outstanding result on this DAC model. For example: THD+N<0.0005%, -130dB idle noise and up to 120dB S/N Ratio. These measurements are rarely seen on D/A converters at this price range.

• By implementation of ASRC, Yulong D100 MKII have achieved excellent anti-jitter performance. The input digital audio signal is first asynchronously processed to 132KHZ with reference to a custom-made 1ppm precision and low phase noise clock source. The output is an extremely low jitter I2S signal then further to be fed into the DAC chip, which results in a highly precise digital to analog convert process and this process is not sensitive to input signal quality. You do not have to spend big bucks to upgrade your source equipment to get the best sound quality downstream with this unique design. 

•  In Yulong's lab test, when the input digital signal is added 80ns of jitter, the Yulong D100 MKII can produce almost same performance as when there is no jitter added, while synchronous DAC's used for comparison  already lost the lock to the signal and cannot work properly.

•  For the analog circuits, the Yulong D100 MKII  brings out neutral and refined sound without excessive coloration. 

•  The USB interface uses the TE7022L (Supports the ASIO and the USB2.0), the I2S signal from USB chip is sent for ASRC and DAC. It can achieve the same performance index as the S/PDIF, Optical or AES/EBU inputs. The THD+N is less than 0.0005%.

• Yulong D100 MKII is also a high performance headphone amplifier, and sound style can be selected by pressing the Sound button on the front panel. The default style Mode 1 is natural and dynamic. Switching to Mode 2 will result in a smooth style, which is suitable for bright-sounding headphones, or if you prefer more "dark and smooth" sound.

•  Two headphone outputs with different impedance: LOW is suitable for headphones with low impedance and high sensitivity such as in ear monitor; while HIGH fits most of bigger headphones. You can also try to get a different sound style by using a same headphone in different outputs.

• Easy operation: Most likely you only need to access the MODE button on the front panel. The last used input channel is stored automatically and will resume when power up. 

• High quality aluminum casing, custom made gold plated connectors result in flawless operation and superior reliability.

• Selectable dual voltage 110/120V or 220/240 operating voltage, 50/60Hz. You can take this unit anywhere in the world and enjoy.
