Buying Guide
- What is your primary use? For gaming and movies, prioritize DACs with good output power and multi-mode DSP (like the Nano ONE Pro or K7). For pure music with minimal setup, entry-level options like Q4 or compact SK02 provide solid improvements.
- How will you connect? If you need USB-C, optical, and coaxial, choose models like Q6, K7, or SK02. If you want portable use, consider the DS2 dongle.
