The Kingrex T20U amplifier with the TA2020 chipset has some additional power which allows for more flexibility when choosing loudspeakers. You can easily reach acceptable volume levels comparable to live performances in medium spaces with loudspeaker sensitivity as low as 86db. Sound is very well articulated and the sound stage is wide, representing a lot of space around the instruments and vocals. The frequency range is also very precise from the right down to the lows. The excellent build quality, finish of the amp and PSU is immediately apparant as well.
The T20U includes an integrated DAC for USB input that uses the Burr-Brown OPA2604AP for low pass filter and Texas Instruments' low-noise JFET-input TL072CP as a DC servo . The op-amps are socketed which makes them easy to swap out or replace.
Included is an AC/DC universal auto-switching type adapter that adapts to worldwide voltages (100 to 240v). DC output ranges from 12.17v to to 12.37v.
Also included is a User Guide & Manufacturer's 1-year Limited Warranty.
