The xDuoo TA-20 is a high performance balanced tube amplifier that is about the size of a sheet of A5 paper and saves a lot of desk space. It comes in an aluminum alloy chassis and has 12AU7 tubes along with a balanced output that delivers 2,000 mW of power. For inputs, it comes with XLR and two sets of RCA. It also has a RCA output port for preamplifier functionality. To top off all these features, the TA-20 has a Class-A transistor expansion, a custom hi-fi capacitor, and a professional volume IC.
