How to Choose a Headphone Amp & DAC
When shopping for a headphone amp or DAC, there are three key factors worth paying close attention to.
1. Output Power and Supported Impedance Match the amp’s output power to your headphones’ impedance. High-impedance cans like the Beyerdynamic DT 990 Pro (250Ω) or Sennheiser HD 650 (300Ω) need amps capable of at least 500mW to perform properly. Check the headphone manufacturer’s recommended amplification requirements.
2. Balanced Output Support 4.4mm pentaconn or XLR 4-pin balanced output reduces noise, lowers crosstalk, and often doubles output power. If your headphones support balanced cables, choosing a balanced-capable amp is the smart long-term investment.
3. DAC Chip Quality and Supported Formats Premium DAC chips from ESS Sabre, AKM, or Cirrus Logic yield higher SNR and better detail retrieval. Support for DSD512 and PCM 768kHz lets you take full advantage of hi-res music from Tidal, Amazon Music, and Qobuz.
