Why You Need a Dedicated DAC/Amp
Your computers built-in audio is an afterthought — noisy, underpowered, and limited in resolution. A dedicated DAC (digital-to-analog converter) and amplifier unlock the full potential of your headphones, especially high-impedance and planar magnetic models.
Key Specifications
DAC chip: ESS Sabre and AKM AK4493 are current leaders. Output power: Planar magnetic headphones need 2W+ at 32 ohms. SNR: 120dB+ ensures inaudible noise floor. Output impedance: Under 1 ohm for accurate headphone frequency response.
