KingRex T20U Tripath Amplifier USB DAC
KingRex T20 U AMP is basically the same Class T (based Tripath Technology) 20 Watt integrated amplifier with an onboard USB interface and DAC (digital to analog converter). It has the convenience for digital life that we are all looking for but without any unexpected noise and distortion of your favorite music.
Why did KingRex design the T20 U?
Today, the computer is ubiquitous in most people's daily life. However, the Hi Fi audio equipment still remains in music lover’s media room and not next to their PC.
Although the PC can handle multi-media display very well, the sound card or the audio chip is for 5.1 or 7.1. It’s good for movies or gaming but it cannot provide the purity of sound for the audiophile, especially the unexpected noise and distortion.
The KingRex T20 U is able get the digital signal directly from your computer with a built-in USB interface and DAC (digital-analog converter). There will be no inflicted noise and distortion so you are able to hear the authentic musicality, no less and no more!
Based on Tripath TA-2020-020 DPP chip. KingRex T20 AMP is capable of 2 ＊ 20 Watts at 4 Ohms with 80% energy efficiency.
The heart of the T20 U DAC is the Burr-Brown PCM2702E which a 32/44.1/48 KHz ready 16-bit stereo DAC with USB interface, on chip clock generator, 8 times oversampling digital interpolation filter and analog output low-pass filter.
The low-pass filters, the analog two-channel signals are handed over to the Burr-Brown OPA2604 op amp acts as output stage preamp.
It also functions as a low-pass filter, taking out the residual digital garbage and turns the audio signals into more analogue sounding stream.
A pair of TL072 low noise dual JFET op amps are assigned to the DC servo circuit for sure the audio signals are clear.
The T20 U has one set of line input and one set of USB interface, both the input sockets and toggle switch are located on the rear panel to keep the front panel as clean as the T20.
Input selection is electronically executed by a relay.

KingRex PSU MKii
The Kingrex PSU MKii is an upgrade Linear power supply for the UD384 USB Dac. This upgrade power option adds another level of detail and resolution to the Dac.
The Kingrex PSU MKii power supply unit is available in a Variety of output voltages. Such as 12V, 9V, 7.5V, 5V. The 7.5v for use with the KingRex UD384 and & UC384. Other versions can be special ordered.
The 5V version can power the Calyx DAC 24/192, Squeezebox Touch, Onkyo ND-S1 iPod Transport, etc.
The 9V version would power a Squeezebox receiver Squeezebox Classic/Duet, M2Tech EVO (7~11V)
The 13V version can power the KingRex T20U, Acoustic Revive RR-77, Nuforce icon, Wadia 170i /171i, TC Electronic Konnekt, 8 Nuforce icon II, Chordette Toucan, Squeeze box boom, ECHO AUDIOFIRE,4 Nuforce HDP, My audio X-02, Cambridge DAC magic, Simaudio Moon 110 LP and Musical Fidelity Vdac mk2 DAC
Inside the PSU Mk2 there's a 48VA toroidal transformer, a regulated power-stabilizing circuit with 8 capacitors, 5 x 2200μF at AC input stage and 3 x 4700uF at DC outputstage. 6N Furukawa PCOCC wiring through out. The unit has a 3 pin Neutrik DC connection on the PSU side to DC jack (electronic side). The included DC jack is a5mm external, 2mm internal type
The switching power adaptor is the most convenient and common power source however it is not a good selection for the music connoisseur who prefers sonic performance over convenience as it has the most noise and distribution due to the high-frequency switching and harmonics in its design. The linear power supply is a better choice for audiophiles. It has less noise and distortion than the switching power adaptor, however, during the AC to DC conversion and rectification process, there is still minute amounts of unavoidable noise and distortion. That’s because the AC power is required to traverse significant circuitry such as transformer, diodes, voltage regulators, and other components.

KingRex uArt Y USB Cable
Power separated USB Cable- Only Purity No Noise
HiEnd USB design, sounds TRUE from the very beginning
We at Kingrex always strive to bring you something a bit more special, using our expertise and knowledge we applied our craft when designing these new USB cables simply because in traditional Kingrex fashion we wanted to bring you the best we could offer.
Our USB cables feature these two important performance enhancing features.
² Signal/power separation
² Cryogenic treatment.
By including these two extra important ingredients in our new USB cables, Kingrex have once again been able to offer you a product that not only looks stunning but it has the sound quality to match.
The Unstoppable trend- USB HiEnd
The USB DAC device should be the most popular choice for most of users as it has two advantages that no one would deny. 1. Convenience – As almost everyone’s PC or Mac should have the USB port, using USB DAC will be very easy for all PC users. 2. Cut off the noise – The most reason for audiophile reject using the computer as source because it might have ripple, noise, high frequency radiation, jitter, and unstable power voltage output. All these problem will cause music with noise and unclear background none of these could be endured. As the USB DAC is external device, it will decrease the affection from the PC substantially. No loss or no distortion is the most important thing while signal transition. The USB cable will play very important role when signal transition.
