How we ranked these headphone amps
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: professional headphone amp
Balanced output and power
Balanced output uses separate paths for each channel. All five amps here have a balanced output: the K11, ZH3, DX5II, GIGAS 1 and Gremlin. Power is quoted per load, so compare the same load: the K11 gives 1400mW at 32 ohms balanced, the ZH3 gives 2570mW at 32 ohms balanced, the DX5II gives 7600mW at 16 ohms, the GIGAS 1 gives 4600mW plus 4600mW at 32 ohms balanced, and the Gremlin gives 1250mW. Match the figure to the headphones you own.
DAC or amp only
A DAC turns digital audio into analog sound; an amp only makes an analog signal louder. The K11, ZH3 and DX5II each pair a DAC with an amp, so they connect over digital inputs. If the source is a computer, the K11 and ZH3 take USB input. The GIGAS 1 and Gremlin take analog input through RCA and 3.5mm jacks or XLR inputs, so they need a separate DAC or an analog source.
Gain, EQ and outputs
Gain matches the amp to sensitive or demanding headphones. The ZH3 has a 3-level gain switch for 16 to 300 ohm headphones, and the GIGAS 1 has dual gain modes for sensitive IEMs and power-hungry headphones. EQ shapes the sound: the ZH3 has bass and treble EQ plus 6 filter types, and the DX5II has a 10-band PEQ with saved profiles. Outputs decide the cable: the K11, ZH3 and DX5II each offer 4.4mm balanced and 6.35mm single-ended jacks, the GIGAS 1 offers 4.4mm and 3.5mm, and the Gremlin offers 4-pin XLR and 4.4mm.
Frequently asked questions
Do I need a DAC with a headphone amp?
Only if the source is digital. The K11, ZH3 and DX5II each include a DAC, while the GIGAS 1 and Gremlin take analog input only.
What does balanced output mean for headphones?
Balanced output uses separate paths for each channel. All five amps here have a balanced output, with 4.4mm jacks on each and XLR on the DX5II and Gremlin.
How much power do planar magnetic headphones need?
It depends on the headphone, not the amp alone. The GIGAS 1 targets planar magnetic and high-impedance headphones with 4600mW plus 4600mW balanced output at 32 ohms.
Can I swap tubes on a tube headphone amp?
On the Gremlin, yes. It works with any 12AU7 or 6922 tubes, new or old, and ships with a matched pair of CORE 12AU7 tubes.
