Featured in our review: This Tiny ( Monoblock Just Hit 417 Watts – Is It a Budget Audio Game Changer?
AIYIMA A20 MONO — true Class-D monoblock power amplifier delivering 300 W into 4 ohm (up to 600 W into 2 ohm at 10% THD) from a chassis smaller than a paperback. Built on the audiophile-favorite TPA3255 chipset with OPA1612 + LME49720 op-amps for a clean, low-distortion signal path. RCA + XLR + 6.35 mm TRS inputs; passive speaker binding posts and a dedicated RCA subwoofer output with adjustable high-pass filter. THD+N of 0.002% and signal-to-noise ratio above 118 dB — measurements that shame amplifiers 3× the price. Run one A20 MONO per channel as a dual-mono stack for a true balanced monoblock rig (each block gets its own dedicated power supply and current path, so left and right never fight over current). Frequency response 20 Hz – 20 kHz within ±0.4 dB. External DC 32-48 V power adapter included. Ideal amp for HiVi-Swans D3.1 MKII, Klipsch RP-500M II, and similar 87-96 dB sensitivity bookshelves.
