The integrated amplifier KingRex T-20 U / PSU (270 / 190 euro) docks directly to the computer via USB and enhanced digitally. Its delicate, delicate sound don’t even bother in the open-plan office and led to enjoyable overtime.

- Data sheet
The KingRex T-20 U stands for some months on my desk, along with the John Blue JB-3 broadband monitors. Read the detailed review of these speakers, on the next double page, but sure the colleague there will lose not a word about the wonderful synergy that arises between them and the 270 euro small amplifiers. Small is extremely fine.
The combination creates a phenomenon that has earned its own name: acoustic homeopathy. I’m going to write now no para-medical nonsense. But you sure know the concept of exponentiation: A preparation should be then the more effective, the more it was diluted. I think not, but my desk system does exactly the same thing with music: seen her even more, depending on the down turn, and this effect has no lower bound on this side of the threshold apparently. The sound remains completely even at lowest levels, the stage far and clean the bass defined, expressive and tired.
The power supply unit PSU inhabited an extra cabin, the KingRex Electronics is dioecious. You can also save 190 euro for and operate the T-20U on the standard plastic power supply only, but I just tried that. The positive effect of the extra toroidal transformer significantly oversized for a 10-Watt amp (together with more precise stabilization) was plain as day: I could hear even quieter. Give it to me.
It is responsible for the fantastic dynamic of this amplifier and the absence of the otherwise inevitable looming in the Micro level electrons Nebula… don’t know. The T20 U is based on the digital amplifier module 2020 of the 2007 defunct company Tripath, driven by two besockelte (and easily interchangeable to the sound tuning) operating rooms and the USB converter PCM 2707 of Burr-Brown. The latter gets beat-tuition of a precise oscillator placed immediately next to it. All of this has been sighted already somewhere else but rarely tipped as clean and precise cutting boards, and with such musical result.
