Description
- Clean amplification with ultra-low distortion
- Fully-balanced architecture
- Ultra-low output impedance
- Massive output power
The Gustard H16 Amp follows hot on the heels of the Gustard X16 DAC, a DAC which implements the world’s first DAC chipset with an in-built MQA renderer. The X16 has been turning heads with its best-in-class SINAD rating. Every DAC needs an amp, and the H16 can be thought of as the X16’s partner in crime. It offers massive power without contributing noise or distortion.
The H16 uses a fully balanced architecture, making it perfect for anyone looking to power balanced headphones (especially power-hungry ones). With four outputs, three of which are balanced, it can accommodate an array of listening scenarios.
Massive output power
If you’re wondering if the H16 can drive your headphones, the answer is almost definitely yes. It delivers huge amounts of power at any impedance: 3700mW @ 64Ω, 2268mW @ 150Ω, 1133mW @ 300Ω, and 566mW @ 600Ω.
Clean amplification with ultra-low distortion
Gustard designed the H16 to pair with the X16 DAC. An ultra-clean DAC deserves an ultra-clean amp, and that’s exactly what they’ve provided.
The H16’s signal-to-noise ratio is over 118dB, meaning that you’d have to crank it to dangerously high levels to hear any hiss or other unwanted noise. To put that number in perspective, the loudness of a jackhammer is 110dB, an ambulance 120dB. So in any normal, healthy listening scenario, you’re going to hear nothing but pure signal.

Gustard is a company dedicated to research and development, aiming to offer high-performance audio desktop-grade DAC and amplifiers at affordable prices. Their products are ideal for music lovers who seek quality audio.
It's not often you come across products which may not be hyped, but surprises you with class-leading performance, and competes with products which are 3x its price. Gustard H16 is one such item, which can be considered to be a great headphone amplifier irrespective of the price bracket. This has a unique presentation, as it does not push the sound frequencies too much. At the same time, its neither mellow or dark, and is fairly neutral, just portraying the tonality of the DAC feeding this. Although not bass heavy, this provides a good and clean bass impact depending on the DAC. H16 sounds magical when driven from Ifi XDSD Gryphon variable (balanced) line out (through 4.4 to dual xlr cable). The vocals sound sweet and textured and there is great synergy with something like Hifiman Arya in this set-up. Other great benefits are - perfect channel matching through its relay controlled digital volume, useability with iems (recommended with 30 ohms or higher), remote control for convenience and so on. All in all this is a highly recommended buy. Thanks a lot for Pritam from TAS for providing a very competitive pricing for brand new authentic products.
Got the Gustard H16 a few days back. Have to thank pritam for personally handing over the amp. As of now, burn in of the amp is in progress as around 50 hours minimum burn in is recommended for it. The amp packs quite a bit of power and sounds very clean and open so far.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES

Let customers speak for us
from 5205 reviewsThe soundstage and imaging in games is awesome. I can hear every minute detail
Very detailed sound and wide sound stage
The quality of the product really good and audiostore experience as well
The audio quality was great... And this is the first time I m buying from audio store... It was good experience and it came very faster than i expected !
The resolution of audio has improved drastically due to the balanced cable. The cable makes my Shanling UA2 Plus DAC + Amp to provide more power to the drivers of my Sennheiser HD620S headphones. So, the volume of the headphones has doubled.
The build is solid and the most impressive thing is the flat sound stage.It is recorded to use a portable DAC to get the best sound possible.Not recommended for bass lovers

Good
Very prompt response
It's very good very energetic sound
Audio quality is too good
The fitting and impact of sound quality and comfort is amazing I would love to buy more this kind of eartips
Most convenient

This was a gift for a friend of mine. The shipping took some time but when it reached them it was shipped the same day and after two days it was received. It came in perfect condition. I'll copy my friend's review below:
"This is most balanced IEM with a touch of warmth among everything out there. The Bass is just a bit much and with a 3db high-pass filter it became perfect. It doesn't get much better from this. The soundstage and imaging is decent and competes with +800$ stuff. The tuning, resolution and timbre is one of the best even under 2k. I'm very much in love with them. The comfort is pretty decent. I haven't got tired of them even after long hours."
The audio quality is very crisp and refreshing
The sound just amplified after using this with my kz castor pro IEMs....it is amazing.
