Headphone Amplifier Reviews

Expert reviews of headphone amplifiers from Schiit, JDS Labs, FiiO, Topping, and more. Find the best amp for your budget and headphones.

A headphone amplifier is not optional for high-impedance headphones. The Sennheiser HD 600, Beyerdynamic DT 990 Pro, and similar 250–300Ω designs are severely underpowered from laptop headphone jacks — they need proper voltage swing to sound correct. Our amplifier reviews focus on whether an amp does that job properly, not on marketing claims.

Our Picks at Each Tier

Under $150 — the JDS Labs Atom Amp+ and Schiit Magni Heresy are the two benchmarks. Both measure near-perfectly and drive everything short of flagship planars without strain.

$150–$300 — the Schiit Asgard 3 and Drop + THX AAA 789 are the step-up picks with higher output power and better headroom for demanding loads.

Balanced output — the Schiit Magnius covers the dedicated balanced amplifier category at $199.

Portable/Bluetooth — the FiiO BTR7 covers Bluetooth DAC/amp for portable use.

What We Evaluate

Output power into 32Ω and 300Ω loads, noise floor at both gain settings, and whether the amp’s output impedance is low enough to avoid interacting with the headphone’s impedance curve. We also assess real-world usability: volume pot quality, build, and whether the amp actually fits into a normal desk setup.
