Why KingRex design the T20 U?
Nowadays, the computer is ubiquitous in many people daily life. But why the Hi Fi audio equipment still only in music lover¡¦s living room not just next to their PC?

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.Appearance

KingRex T20 AMP has more power compare with the original T-AMP with the loudspeakers of average sensitivity (86~90dB, 4~8Ohms). You can easily reach levels comparable to vivid performances in medium space as 6moons review~ The pace of the KingRex T20 AMP was more relaxed, stretching out on a more expansive, deeper set soundstage. This valve bloom syndrome was not masking any definition or instrument placement but rather enhancing them in a more musical way. Go on review (http://www.6moons.com/audioreviews/kingrex/t20.html
