Zhaolu
Zhaolu D3 DAC.
This DAC supports the TG-Link input for PC sound. When used with the computer soundcard shown below, the digital information is transmitted via this new interface.
Following is some information culled from the manufacturer's website, please forgive us if the translation is a little spotty here and there...:
Zhaolu D3 stereo digital audio decoder is a new generation of high-standard decoder product. The Zhaolu D3 can accept (24bits-192khz) SPDIF digital audio signal format. Four digital inputs can completely meet user requirements. Inputs: SPDIF optical interface, two coaxial SPDIF input interface, and the high-speed buffer TG-link personal digital audio interface. Through the control panel, users can choose the necessary input to accept the desired digital audio signal. Users can assign a designated priority switched digital audio input, which will stay selected even when switched off and on again.
In the pursuit of excellent performance, the Zhaolu D3 will be exzceptionally well shielded, use circuit boards and PCB design of the highest quality, and carefully selected high performance parts. The Zhaolu D3 test results exceeded the minimum resolution of the test equipment.
Following is some of the test results:
- -115dB -115dB (A-weighted)
- 113dB dynamic range (A-weighted)
- -100dB 0.001% Total Harmonic Distortion : "-100dB (" 0.001%)
- -111dB 1KhZ -111dB 1KhZ stereo separation :
- -108dB 300hZ -108dB (300hZ--40KhZ)
Zhaolu D3 uses Cirrus Logic CS4398 digital-analog conversion devices, and carefully match the peripheral circuits.
The manufacturer is also supplying two upgrades free of charge: Key power supply and analog audio stage capacitors will be changed to ELNA BP cap's to inprove the overall quality of sound.
Replace 2 OPA-604 in audio stage with LT-1028 to obtain higher frequency extension and allow greater dynamic contrasts.

Zhaolu D3 $299.95 SPECIAL $279.00
Add TG-LINK PC Card $99. Add PC Link II $109.95
Due to numerous customer requests, we are now offering the Zhaolu 2.5 DAC.
We are going to offer the "C" model of the 2.5, as well as the upgraded headamp board as an upgrade. The D2.5C uses the CS4398 DA chip, which is an improvement over the "regular" model, which uses the AD-1852 chip.
In addition on the "C" model, the vendor installs two upgrades,free of charge: The OPA-2604 in the high speed power supply is replaced with the AD-08, which offers a cleaner presentation. The 2 OPA-2604's are replaced with LT-1057's to obtain better high end extension and tighter, more tuneful bass. The original OPAMPS are included if you wish to switch them back. However, please be aware that opening
the case will void the one year manufacturer warranty.
Above is a picture of the upgraded discrete headamp module next to the standard module. If you are a headphone lover, this upgrade is a "must do". While the headamp that is uspllied with the unit is good, this amplifier is on a whole new level! The stage really opens up, bass solidifies and goes MUCH deeper and the midrange detail is vastly improved. If the upgraded discrete headamp module is purchased at the same time as the DAC, we will install it
for no charge.
