Good, but a firmware update is needed to display larger characters on the screen... read...

This is a very good amplifier. I compared it with a Marantz SR4400, a Class AB amplifier, and a Schneider Team 6150 amplifier with an STK4181 II IC output stage (2x45W). The sound of the AIYIMA D03 is better than both. I got it from a European warehouse with a 36V 5A power supply. It’s connected to Elac ELS 135 speakers, which have 4-ohm impedance, two 20cm woofers, a midrange driver, and a tweeter. These are 110/135W speakers, but the AIYIMA D03 is so powerful that it's more than enough. On YouTube videos, people don’t like the analog input, but it has a better DAC than "CD quality". At most, you might need to increase the treble by +2dB on the equalizer compared to the other inputs, but it's no worse than the Marantz SR4400 even without treble boost. The Marantz DSP and DAC are also of very high quality, but it has a much higher noise floor than the AIYIMA D03. The Bluetooth sounds great without noise as well. You won’t have any issues with it. I tried very hard to compare the sound to the Marantz using a lot of high-quality music, but I can’t hear any difference at any frequency. The only difference is that the Marantz has a much higher noise floor. The only negative for me is the display size. It would be nice if, with a firmware update, it could display the volume level, input selection, and equalizer settings in large characters when adjusting them. The remote control feels a bit cheap, but it works fine. I disassembled the amplifier and moved the infrared receiver slightly forward, so now it detects the signal well even from a greater distance. I was very worried about how it would sound, but I was pleasantly surprised. This is my first Class D amplifier.
