Top-rated products in the Headphone amplifiers category

Here's a ranking of the top rated products in this category. To give you a quick overview, we've also added some key information about the products.

1. RME Audio ADI-2 DAC FS

The updated ADI-2 DAC uses AKM's AK4493 in a special circuit variant developed by RME engineers that allows the chip to perform at its best. Be it noise ratios of 123 dBA, distortion lower than -120 dB, or THD+N of -117 dB, the device delivers outstanding measured values. Even the IEM output, with -118 dBu already the world's lowest noise headphone output, improves to a sensational -120 dBu. In addition to all this, there is 4 dB digital headroom, so that even high intersample peaks do not produce any audible distortion. Finally, the device now also offers a clear reserve in the volume setting. +2.5 dB result in a still undistorted analog output signal.

All these improvements are completely transparent in the previous menu navigation. There are no changes to the predecessor in operation, features and behavior, which is why neither appearance nor name have changed. The only difference: with 'Low Dispersion' another digital filter is available for selection. Explanations for this filter can be found in the detailed manual of the ADI-2 DAC.

5. TIE Headphone Amplifier 4CH

The robust and compact TIE Studio headphone amplifier can be used for up to four headphones for simultaneous monitoring of the main mix with separate volume selection. Four powerful, low-noise stereo amplifiers provide superior sound quality at any volume, whether for live or studio applications. 

6. iFi Audio Zen CAN

With the Zen CAN, you can finally get the best out of your headphones. With 52 times the power and features you'd only find in high-end products, iFi Audio's amplifier is the best choice if you want to enjoy balanced, rich sound. When you connect your headphones to laptops, smartphones or digital-to-analogue converters, they are often unable to supply the necessary power. By default, such devices output power of less than 1.0 volt, which is nowhere near enough, especially for high-end models. With the Zen CAN, you can finally unleash the full potential of your headphones. The practical amplifier has the circuit design of the professional model Pro iCAN and offers you an output of up to 15.1 volts. This means that even demanding headphones are supplied without any problems. Be surprised how many beats, how many basses and how many sounds you have never perceived before. In its essence, music is always designed to be played loudly through speakers - an experience that is quickly lost when output through headphones. It's this sense of feeling the sound around you and experiencing it to the fullest that the Zen CAN's 3D sound circuitry brings back. Instead of being trapped in ear cups, you as the listener are at the centre of balanced, perfectly balanced sounds. An experience made possible not least by XBass technology. Especially with open headphones, the system compensates for their natural bass weakness, brings rich, low tones into the overall concept and integrates them playfully into your three-dimensional sound experience. Experience the sound of your headphones as you never could before. You can. The Zen CAN. 

7. iFi Audio hip-dac2

The hip-dac2 in hip orange is colourful, tech-savvy and a real sound pro! The hip-dac2 bypasses the DAC (digital-to-analogue converter) and amplifier circuits in your smartphone, tablet, notebook, PC or Mac, greatly improving headphone sound. Connect your playback device to the hip-dac2 via USB, connect your favourite headphones or in-ear earphones and the hip-dac2 delivers sound that is bursting with dynamics and detail. The integrated Burr-Brown DAC chip was chosen for its lifelike, highly musical sound quality. Together with iFi's proprietary circuitry, the hip-dac2 delivers outstanding sound quality for all digital audio formats, including bit-perfect PCM, native DSD and MQA. The 16-core XMOS chip, which processes data via USB, offers a high clock rate and plenty of memory. This improves the overall performance of the hip-dac2, so that it can even handle full MQA decoding. A high-quality quartz clock also contributes to a particularly pure, clear sound. Whether you're working in your favourite café or chilling on your daily commute, sunrise or sunset, you'll definitely want the hip-dac2 with you. The amplifier stage can output 400 mW of power, ensuring compatibility with a wide range of headphone and earphone types without sacrificing quality. Even high-impedance headphones are easily driven thanks to an output voltage of 6.3V into 600 ohms (via the balanced output). The PowerMatch function allows the level of amplification to be matched to the load of the connected headphones by perfectly adjusting the input sensitivity and thus the signal strength for your headphones. 

8. RME Audio ADI-2 DAC

To better appeal to home and hi-fi users, RME replaced some of the studio features with typical hi-fi features. RME now presents the ADI-2 DAC, equipped with an adapted as well as an extended range of functions and a simplified operation.

The new ADI-2 Pro FS R Black Edition features the AK4493 chip, slightly improved specifications, and comes with the new enhanced Multi Remote Control (MRC).

Thanks to the numerous connectors the ADI-2 Pro shows a high compatibility. At the front of the chassis two Extreme Power stereo headphone outputs have been installed, one of which has an ADAT compatible optical SPDIF I/O. A coaxial SPDIF as RCA as well as an AES I/O via XLR can be integrated via the cable whip. Furthermore the unit offers two servo-balanced analog inputs via XLR/jack combo jack and separate balanced and unbalanced outputs as XLR and jack port. The RME SteadyClock FS technology provides perfect jitter suppression and stable clocking, no matter if internal or external clocks are used.

10. iFi Audio ZEN One Signature

With the iFi ZEN One Signature you have finally found the perfect digital to analogue converter you need for your setup. Enjoy perfect sound from any of your devices - easily via Bluetooth, USB or S/PDIF. As much as we benefit from the easy music playback of our mobile devices today, smartphones and the like are not designed for high-quality sound. They are small all-rounders, but lack the specialisation for perfect sound, especially for audiophiles. Even the familiar CD player can only manage the minimum standard. This is precisely why you need a good digital-to-analogue converter. This is specially designed to convert digital data into analogue signals for your output devices. The advantage: you get a much higher quality, more balanced and clearer sound. With its USB, S/PDIF and Bluetooth connectivity options, the iFi ZEN One Signature is not only easy to pair with all your favourite devices, but also has an increased range thanks to its antenna. Simply place, pair and experience pure sound from any source throughout your home. Better sound quality, but what does that mean? The quality of a music file is usually determined by its sampling rate. For a standard CD, this is 44.1 kHz. The ZEN One Signature supports Bluetooth signals with up to 96 KHz as well as DSD256 - which means that the sampling rate is 256 times better than that of a CD. In addition, the D/A converter delivers PCM up to 384 kHz and MQA decoding. These files in particular are a special highlight for enthusiasts, as they are certified by studios and allow you to listen to music exactly as it was intended for listeners. For you, this means that you swap standard playback for razor-sharp, unique sound that you will never want to miss again.
