This dual-DAC layout feeds a multi-channel summation stage designed to lower noise and improve linearity before the signal reaches the analog section. On the digital side, USB decoding supports up to 768kHz\/32-bit PCM and native DSD512, while optical and coaxial inputs support up to 192kHz\/24-bit and DoP64. \u003c\/p\u003e\n\u003ch3\u003eSignal Integrity\u003c\/h3\u003e\n\u003cp\u003eThe Alpha uses a four-layer PCB that routes critical signals on protected inner layers, with grounded outer layers helping shield interference.
