What is a headphone amplifier? And what does it do?
Like a stereo amplifier, it converts the signal from your source (computer, smartphone, turntable) for use with quality headphones. They also include a DAC which converts your digital files into analogue music and offers significantly better sound than your computer or smartphone can manage on its own.
Do I really need a headphone amplifier?
If you’ve invested in a pair of high-quality wired headphones, even a cheap headphone amplifier will power them more effectively and present new levels of depth and detail in your favourite recordings.
Will a headphone amplifier improve audio quality?
Absolutely, but the quality of the source material is vital. Compressed MP3 tracks can sound terrible, so you’ll need to play hi-res music files, CD-quality (16 bit – 44khz) or ideally higher (24bit – 96khz/192khz, lossless FLAC, WAV, ALAC or DSD) to hear the greatest benefit.

The perfect introduction to headphone amps, this superb value desktop USB-powered DAC (digital-to-analogue converter) will instantly elevate your computer’s audio output and make the most of a decent pair of headphones. A stylish, compact all-metal design, it handles most hi-res formats including MQA (Master Quality Authenticated) and you can adjust the output power depending on whether you’re wearing in-ear monitors (IEM) or larger over-ear designs.

Chord Hugo TT2 review
Chord Electronics are the current kings of headphone amplification and have been blazing a trail in audiophile circles with their quirky looking but sensational-sounding products. The pocket-sized Chord Mojo (£399) first showed how easy it is to improve audio performance vastly, but the Chord Hugo TT2 opened my ears to another world.
At £4,000, we’re deep into audiophile territory here and many thousands of words have already been written about the custom-coded Xilinx Artix 7 FPGA (Field Programmable Gate Array) with 86 208MHz cores running in parallel. But what difference does all this techno jargon really make to your listening enjoyment?
Paired with the similarly priced Audeze LCD-4z headphones and my MacBook, streaming everything from Tidal Master (MQA) recordings to 24bit/192kHz files and uncompressed FLAC, the Hugo TT2 excels in every sense, reminding me of time well spent in demo rooms listening to £100,000 audio systems. In short, it’s products like the Hugo TT2 that drive people to make impassioned requests to their bank, or alternatively into hi-fi journalism. A real treat.
