There has been a thinking that amplifiers have to be big. But there is no wrong in thinking amps can be small and perform well to its size too.
TPA3116D2 has been a favourite amp for many audio enthusiasts for many reasons – tiny, efficient, powerful, clean and affordable are some traits of this fantastic little winner. At a power output capable of outputting 50 watt-per-channel, it is no slouch. With our included DC power supply rated at 24v 2A that comes together in this package, it is bound to get the maximum optimal juice needed to run this amp and output serious power to even floor standers. We are sure the volume knob will not need to be past the 10 o’clock position in most usages.
Underneath the proprietary acrylic case designed by QA is small footprint of printed PCB that uses SMD resistors. Less is more is true in this implementation. By keeping the circuitry less complex than some of the similar class of amps who could be huge in size, what we are getting is cleaner signal and output.
Importantly, the components that caught the eyes here are really the capacitors which have been selected and chosen in detail to be used in this board. Using Nichicon FW, WIMA and Panasonic FW series of capacitors are one the best combinations for this similar approach of application, circuit design and budget. These modifications presented a forward leap of improvement over the stock components and increased the value of this amp further.
UK-plug DC 24V 2A power supply and 5.5*2.5mm DC lead wire is provided.
