Do You Actually Need a DAC/Amp?
Honest answer: probably not. If your headphones get loud enough without distortion from onboard audio, a DAC/amp changes almost nothing audible. You do need one if:
- Your headphones are high-impedance (e.g. DT 990 250Ω, HD 600 300Ω) and sound quiet/thin.
- Your onboard audio has audible hiss or interference.
- You want a physical volume knob (legitimate quality-of-life).
HeSuVi works identically with or without external gear — it processes audio before it reaches the DAC.
The Only Two Upgrades Worth Buying
Skip the $500 stacks. For gaming, the value curve flattens fast:
Apple USB-C to 3.5mm Adapter
Measures shockingly well for ~$9 — clean, enough power for IEMs and efficient headphones. The rationalist’s DAC.
Best for: IEMs and easy-to-drive headphones
Fiio K11
Desktop DAC/amp with real power for 250–300Ω headphones, clean measurements, physical knob. Everything most gamers will ever need.
Best for: DT 990 250Ω, HD 600, HD 560S
The Bottom Line
Do not buy a DAC/amp until your headphones demand it. If they do, the Apple dongle covers efficient gear for $9, and the Fiio K11 covers everything else. Money beyond that buys features and furniture, not audible gaming advantage.

Frequently Asked Questions
Does a DAC improve HeSuVi’s virtual surround?
No — HeSuVi’s processing happens in software before the DAC. A DAC only affects the final analog conversion quality.
What DAC for DT 990 Pro 250 ohm?
Something with real power like the Fiio K11. The Apple dongle is not enough for 250Ω.
Is onboard audio bad for gaming?
Modern onboard audio is usually fine. Upgrade only if you hear hiss/interference or your headphones are underpowered.
