In August 2017, when I visited the Hong Kong International Recordings Fair, I was fortunate to hear a digital amplifier with a price of 78,000rmb. Since that ear, I changed the idea of not being able to listen to the class D amp and created the idea of making it.
After the recommendation and guidance of Ti Chinese engineers, the final selection of TPA3255 at zero- is that the most important factor is that the sound is good and the dynamic is very strong.
After nearly eight months of schooling at the zero-zone Hong Kong team, it was finally available in the market.
