hearing-protection-index

A hi-fi philistine once asked me why old guys buy great sound systems when their hearing has inevitably been impaired by the ravages of time. For once I came up with an answer without having to think for half an hour and explained that hearing loss was the main reason why you need a better […]

vinyl-accessories-index

Getting a turntable is the beginning of a beautiful journey into sound but like any other precision machine a turntable and the vinyl it plays benefit from careful treatment. Vinyl is a fabulous but fragile medium, one of the reasons that CD was able to change the music industry is that ill treated vinyl and […]

upgradable-system-index

What upgradable means in the context of a sound system is the option to improve sound quality by changing certain parts rather than replacing the whole thing, usually in a piecemeal fashion, eg one new component or cable at a time. You can upgrade a car by putting better tyres or a sporty suspension on […]


BOTW-index

The power supply is the heart of any audio component, it pumps electrons rather than blood but without it amplification and processing can’t happen.

network-set-up-index

Improving a streaming system depends on the nature of the system. The most basic and straightforward streaming system is a laptop and a DAC (digital to analogue converter).

room-acoustics-index

The biggest thing you can do to improve the sound of a music system is to make changes to the room. The sound produced by a pair of speakers bounces off the walls, floor and ceiling and the nature of those structures has a significant effect on what you hear. You can hear this if […]

vertere-pulse-hb-usb-index

It’s a nuisance that cables make so much difference and I can understand why some flatly refuse to accept that they do, it must make life a bit simpler. However, all it takes is a quick comparison in a reasonably revealing system and anyone can hear the inconvenient truth, a situation that is not limited […]


longdog-audio-quartz-index

Contrary to the view that some people get, reviewing audio equipment is a ‘pastime’ that is fraught with dangers. For a start, the primary measuring ‘implement’ is a very personal, and individually flawed pair of ears. Secondly the environment varies not only with every reviewer on the planet, but also in terms of humidity, temperature, […]

Seismic-Podium-index

A car’s suspension has a number of functions but one of them is to isolate the driver from bumps and irregularities in the road surface, to do this a suspension system consists of a spring and a damper (or shock absorber). The spring is selected on the basis of the weight it has to support […]
