It improves sound quality by isolating the DAC from computer noise and providing a cleaner clock signal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a DDC if my DAC already has USB?\u003c\/strong\u003e\u003cbr\u003eA: If your DAC has a high-quality USB input (e.g., with XMOS interface), a DDC may provide diminishing returns. However, for DACs with mediocre USB inputs or for IIS (I²S) connection, a DDC can provide significant improvement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the U26 require driver installation?\u003c\/strong\u003e\u003cbr\u003eA: The U26 uses UAC2 (USB Audio Class 2), which is natively supported by macOS and Linux.
