Keith Howard takes a look at the role capacitors play in audio circuits and explains how they influence sound

Was there a better time to be a hi-fi enthusiast than the late 1970s and early 1980s? It's hard to argue against it because there was so much going on, what with the development of digital audio on one hand and the rise of subjectivism on the other. Suddenly turntables and amplifiers were no longer judged by wow and flutter, rumble and price tag or power output, total harmonic distortion and price tag, but by listening to them. Shock, horror!

Steve Harris brings you the story of the influential audiophile jazz label

History books tell you that jazz first crossed the Atlantic with the Original Dixieland Jazz Band, who made their first records in 1917 and came to England in 1919. And that it was the coincidentally-named orchestra leader and composer James Reese Europe who first brought genuine African-American music to French ears with his black US army band in 1918.

Is there an open-reel tape revival, asks Ken Kessler

If, in 1999, you were told that vinyl would enjoy such a massive revival that in 2019 HMV would be opening a flagship store in Birmingham stocking 25,000 records, and that turntables and LPs would appear in mainstream TV ads for watches and life insurance, you'd have laughed in disbelief. But then you would have paused, because both records and turntables were never entirely out of production.

Should you invest in good acoustics? Keith Howard has some sage advice

Most of us will have asked ourselves at some point whether our next upgrade should be not to our hi-fi system but rather to the room we use it in. Could £1000 spent on absorbents and diffusers make a more profound difference to sound quality than spending the same amount on, say, a cable upgrade or a new pick-up cartridge?

Keith Howard revisits the question of headphone headband resonance

Shortly after my first Investigation into headphone headband resonance was published [see HFN Jun '14], Owen Jones – he who designed THX's Achromatic Audio Amplifier circuit – pointed out to me that I could have done a better job of it.

Do headphone headbands carry unwanted sound? Keith Howard finds out

Imagine that instead of each of your stereo loudspeakers sitting in splendid isolation, optimally aligned with respect to the listening seat, there was a large band of metal or plastic curving between them, joining the two cabinets. If you know anything of loudspeaker design and the efforts taken to quell structural resonances, you'd immediately suspect this structure of colouring the sound and – by carrying vibrations from one speaker to the another – of messing with the stereo image.

Johnny Black examines the booming business of music merchandising

Here's a story I wish I didn't have to tell. Unfortunately, not to tell it would mean ignoring the alarming truth that recorded music is no longer – at least commercially – always the most important element in the recorded music industry.

Keith Howard explains how and why HFN has expanded its test regime

Time flies when you're having fun. I bought the equipment to measure headphones for Hi-Fi News as long ago as May 2007, since when I've tested around 115 different models for the magazine. These have included circumaural (over-ear) designs, supra-aural (on-ear) and insert, active and passive, priced from under £100 to almost £5000.

Tim Jarman tracks the trends in the current vintage hi-fi market...

Vintage hi-fi, like many collecting and preservation hobbies, is subject to the '30-year rule'. This states that today's top collectables are those products that were new about 30 years ago. The reasoning is that when you are young you covet certain items as objects of desire, yet lack the means to buy them. As life progresses, you (hopefully) become wealthier and look again at what it was that caught your imagination when young.

They're crucial to hi-fi, but how do they work? Keith Howard explains all...

There isn't much in a modern hi-fi system that would be familiar to the great 19th century English physicist Michael Faraday. But a time-travelling Faraday – bemused by radio frequency communication, lasers and sound reproduction in general – would find something reassuringly familiar in the transformer. For it was he who first demonstrated that electromagnetic induction can be used to link one electrical circuit to another.

The latest wireless tech could be a boon for audio, as Barry Fox explains

The hype cycle is well under way. 5G is coming, starting slowly this year and rolling out through 2020 and beyond. But who cares? It's nothing to do with hi-fi and music, is it? Just the Fifth and latest generation of phone technology, which – yawn, yawn – works faster and better than the Third and Fourth Generations that have previously been heralded as the be all and end all of mobile phoning and lo-fi MP3 streaming.

Andrew Everard explains how to integrate online music into your system

Streaming? It's simple: you plug your smartphone's headphone output into your amplifier using a 3.5mm-to-stereo-phono cable, tap the free Spotify app, and you're in business. It's hard to see what all the fuss is about really, isn't it?

Andrew Everard brings you his guide to superior sound on a shoestring

The old saw that schooldays are the happiest of your life, jumpers for goalposts an' all, has its parallels in hi-fi. Ask many an enthusiast of a certain age, and they'll go a bit misty-eyed at the thought of their first 'proper' system, bought with a mixture of summer job earnings and that first student grant – yes, once upon a time you got given money to study.

Want the best bass from your subwoofer? Keith Howard has the answers

Is it my imagination or has the subwoofer faded from audiophile affections? In the 1990s a generation of audio lovers discovered that subwoofers could do unexpected things: not just add low-bass heft, but also improve midrange sound quality and the spaciousness of the stereo image.

The prince of synths talks high-end hi-fi while premiering his new album

Jean-Michel Jarre likes what he hears. And it's not only the sound of his new album, which he is playing to an eager audience packed into the Audiofast room at the Audio Video show in Warsaw, but the very audio system on which it is being played.

'My new album is a good test for loudspeakers,' he says smiling, 'because I know that it has lots of different frequencies. This means that it's hard to hear the whole effect on some hi-fi systems, but this one is highly capable.'
