Fully Balanced Design Starting from the Dual DACs to Output
The DX150 utilizes two AK4490EQ chips. Each AK4490EQ has 2 built-in DACs. This means that the DX150 has 2 DACs in parallel for each channel. The DXC150 also has several ultra-low noise power regulators that provide the clearest power for the DACs. Panasonic film capacitors and symmetry topology, that altogether utilizes the full potential of the AK4490. On our test equipment (APX525), we measured -110dB on THD+N and 118dB for S/N, which shows the highest performance of the AK4490.
Full Synchronization Technology: TCXO, PLL
The DX150 is very different compared to the multi oscillators-based DAC. With this synchronization technology, TCXO and PLL, the DX150 reduces jitter to an extremely low level. Also, with this technology, switching oscillators for different sample rates are no longer needed, which eliminates the popping sound when oscillators are changed. This is the first time PLL technology usually found on high-end desktop DACs has been used in a portable digital audio player. Our PLL technology makes the input clock and output clock nearly identical and by providing this very precise clock, sound quality is improved, enhancing the ultimate musical experience.
