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?

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?

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!

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.

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.

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.
