The Topping TP21 features brushed aluminum faceplate and black aluminum cabinet. The volume control is accentuated with a subtle blue LED illumination that when on surrounds the volume control. The unit features high quality gold RCA inputs and gold banana plug speaker connections. The on/off switch is located on the rear of the unit making the front of the amplifier clean and sleek.

A unique feature of the TP21 is the headphone output on the front faceplate. The headphone output has its own pre-amp that disables the speakers when headphones are plugged in and will easily drive any headphones in the 16-200 Ohm range. The Topping TP21 Class T amplifier is manufactured using the highest grade components, including ELNA audiophile grade capacitors, Dale resistors, and ALPS volume controls. Makes a great gift for yourself or any audio enthusiast.
