250-ohm headphones — the Beyerdynamic DT 770/880/990 Pro lineup being the most common examples — need meaningfully more voltage swing than a phone or laptop headphone jack delivers, which is why they sound thin and quiet straight out of a built-in output. What matters when shopping is an amp’s rated output into a 300-ohm load specifically, not its headline power spec into 32 ohms, since plenty of “powerful” amps are only powerful for low-impedance IEMs. The list below runs from sub-$110 desktop amps that are genuinely enough for most 250-ohm cans up to boutique balanced amps that cost several times as much — boutique audio pricing sits well above general consumer-electronics intuition, and the prices here are real retail, not estimates.

The picks, in detail
JDS Labs Atom Amp 2
JDS Labs’ current-generation budget desktop amp, an all-metal update to the long-running original Atom.
- Octo-buffer output stage
- Single-ended 6.35mm output
- All-metal chassis
- Plenty of clean power for 250-ohm Beyerdynamics at this price point
- Backed by JDS Labs’ direct US support
- Single-ended only — no balanced output
- No DAC included, so you need a separate USB DAC or onboard audio
Schiit Magni Heresy
Schiit’s entry-level op-amp-based desktop amp, a mainstay budget recommendation for 250-ohm dynamic headphones.
- Op-amp based topology
- Single-ended 6.35mm and RCA input
- Made in the USA
- Widely recommended specifically for driving Beyerdynamic 250-ohm headphones
- Compact desktop footprint
- No balanced output
- Basic feature set — no DAC, no remote, no headphone impedance switch
Monoprice Monolith Liquid Spark (by Alex Cavalli)
A budget desktop amp designed by Alex Cavalli (of Cavalli Audio), sold under Monoprice’s Monolith line.
- Cavalli-designed discrete output stage
- RCA input, single 6.35mm output
- 1.3W into 50 ohms rated output
- Well-regarded design pedigree at a budget price
- Enough headroom for most 250-ohm dynamic headphones
- Single-ended only
- No DAC or balanced output
FiiO K7
A combo DAC/amp with a desktop-class output stage, useful if you’re driving 250-ohm cans straight from a computer’s USB port.
- Built-in USB DAC (ESS chipset)
- Both single-ended and balanced 4.4mm output
- Bass boost and gain switches
- Skips buying a separate DAC — one box covers both
- Balanced output available if your headphones have a balanced cable
- Bulkier desktop unit than a pure amp like the Atom or Magni
- Balanced output only helps if you already have (or buy) a balanced cable
iFi Zen Can
A desktop amp from iFi’s Zen line with a distinctive 3D-Holographic soundstage-widening feature and adjustable gain.
- XBass and 3D+ soundstage modes
- Balanced 4.4mm and single-ended 6.35mm outputs
- Multiple gain settings for different headphone impedances
- Gain switch specifically tailors output for higher-impedance headphones like 250-ohm Beyerdynamics
- Balanced output included at a mid-range price
- No DAC — needs a separate USB DAC or source with line-out
- External power brick adds desktop clutter
SMSL SH-9 (THX AAA-888)
A balanced desktop amp built around THX’s AAA-888 amplifier topology, sold with THX certification.
- THX AAA-888 amplifier modules
- Balanced 4.4mm and XLR outputs plus single-ended
- THX-certified low distortion
- THX AAA topology delivers clean, high-current output well suited to 250-ohm loads
- Balanced XLR input/output for a full balanced chain
- No onboard DAC
- Feature-dense interface is less plug-and-play than the budget single-knob amps
Schiit Jotunheim 2
Schiit’s modular mid-tier amp, sold as an amp-only unit or with a plug-in DAC card, moving up into genuinely high-power balanced territory.
- Modular design accepts optional DAC or phono cards
- Balanced and single-ended outputs
- High-current output stage
- Balanced output plus real headroom for demanding 250-ohm and higher-impedance cans
- Modular card system lets you add a DAC later instead of buying a second box
- Meaningfully pricier than the budget desktop amps on this list
- Card-based expansion adds cost if you want the DAC option
Topping A90 Discrete
A fully discrete (no op-amps), high-power balanced desktop amp aimed at measurement-focused audiophiles.
- Fully discrete NFCA output stage (no op-amps)
- Balanced 4.4mm/XLR and single-ended outputs
- Two gain settings
- Among the cleanest-measuring amps in this power class, with headroom to spare for 250-ohm loads
- Balanced output plus very low distortion figures
- Priced well above the budget and mid-tier amps here
- Overkill headroom for most 250-ohm dynamic headphones specifically
Monolith by Monoprice THX AAA 887
Monoprice’s THX-certified balanced amp, built around the THX AAA-887 module for high power with low distortion.
- THX AAA-887 amplifier module
- Balanced and single-ended inputs/outputs
- High power output rated for demanding headphones
- THX AAA-887 delivers strong current into high-impedance loads like 250-ohm Beyerdynamics
- Balanced connectivity at a lower price than the Violectric or Topping options here
- No onboard DAC
- Utilitarian styling compared to boutique-brand competitors
Violectric HPA V222
A German-made boutique balanced amp, the priciest and most headroom-heavy option here by a wide margin.
- Fully balanced discrete circuit design
- Multiple gain stages and impedance-matched outputs
- Hand-built in Germany
- Massive power reserve well beyond what 250-ohm headphones require, with room to grow into harder-to-drive planar headphones later
- Boutique build quality and a long track record among headphone enthusiasts
- Priced multiple times higher than every other amp on this list — genuinely boutique-audio pricing, not a typo
- Complete overkill for 250-ohm dynamic headphones alone if that’s the only gear you own
Buying tips
- Compare amps by their rated output into 300 ohms, not 32 ohms — a spec sheet that only lists power into 32 ohms tells you almost nothing about how it’ll drive a 250-ohm Beyerdynamic.
- None of the amps here include a DAC except the FiiO K7 and SMSL SH-9 — if you’re starting from a bare computer USB port rather than an existing DAC or audio interface, budget for that or pick one of those two combo units.
- Boutique balanced amps like the Violectric V222 cost several times what the budget options do for headroom most 250-ohm dynamic headphones don’t actually need — they make more sense if you plan to eventually add harder-to-drive planar magnetic headphones.
