Our take
If you are interested in knowing the measurements and opinions from a trusted reviewer.
Aiyima A07 is one of the best amplifiers in this price category, if you are looking for a all rounder amplifier with huge amounts of power that can drive speakers than this is the one to go for
For the price point, The Aiyima A07 really shines and if you add a value DAC like a Topping D10 / IFI Zen Dac AIR / Topping E30, you will be getting some pretty good performance out of this little but powerful amplifier
As for speakers, this amp will do well with the Micca RB42 / Kanto YU Passives, you'll be getting a very good sounding system for below RM2000
We at techx highly recommend this amplifier if you are on a budget but want the best performing amp at this price point.

Two input ways : 3.5mm AUX Audio input / RCA Audio input
Note: When using a 32V or 36V power supply, the sound quality of the A07 amplifier will be better, the distortion rate will be low, and the service life will be longer, but the power can only reach the size of the voltage multiplied by the current. For example, using a 32V 5A power supply, the power can only reach Max 160W.
Therefore, please choose the speaker and power supply reasonably according to the requirements, so that the system can achieve the best effect.
