This was a superb affordable audiophile valve amplifier that was launched in 2012 for the princely sum of £1,700. “The original Stereo 40 was born in 2000, and was at the heart of what we do, top quality amplifiers at a reasonable price,” said chief designer David Shaw. This is a jumble of ideas with […]

The famous 845 power triode began life as a radio transmitting vacuum tube, with a physically huge anode dissipation of 75 watts and an anode voltage of 1,250V. Because the thoriated tungsten filament – which shined like a lightbulb – was powered at 10 Volts and 3.25 Amps, any transmitter running a large number of

We’ve all heard about how fantastic the Leak Stereo 20 is. It was a superbly designed ‘do-it-all’ stereo valve power amplifier with enough power to drive most loudspeakers of the time when it was introduced in 1958. It was a development of the original mono TL12 Point One, using the same fundamental circuit as Harold

Farad Azima, his brother Henry, and Stan Curtis were the founding directors of Mission Electronics, which was founded in 1977. Another intriguing new British hi-fi firm to emerge from the ‘Silicon Fen’ around Huntingdon, Cambridgeshire – the UK’s equivalent of Silicon Valley, if you will – it quickly established itself with the likes of A&R

Class D, of course. I’m not a fan, but only “so far,” because I don’t have any philosophical issues with it. Experience has taught me that it’s not so much what you do as it is how you do it, and Bruno Putzeys seems to agree. You may not know who he is, but he

The tale of the Musical Fidelity A1 design is already well-known. Tim de Paravicini accepts the challenge. “I strive to be innovative, and if I can avoid it, I don’t duplicate anybody,” he explained. “It all started with a circuit on a breadboard that I created with low feedback and that acted like a valve

When the 3155 was introduced in January 1985, NAD touted it as “two products in one.” “As a preamplifier, it rivals the sound characteristics of most discrete audiophile preamps while outperforming them in terms of operating versatility.” It pushes even problematic loudspeakers to shockingly high volume levels with clean, substantial, full-bodied musical sound that is

Some may dismiss this as merely another of the many power amplifiers made by the Salisbury solid-state specialists over the years, but I believe it has something unique to offer in the grand scheme of things. Naim Audio rose to prominence with the NAC 32 and NAP 250, despite not being the company’s first preamp/power

It’s been a long time since Naim Audio Ltd. initially opened its doors in a Wiltshire backstreet in 1973, and since then, the company has grown in popularity and reputation. Julian Vereker, the firm’s founder, once stated that he started the company to manufacture hi-fi equipment that he and his friends would enjoy listening to.

Who would have guessed? Oppo Digital Inc., a California-based spin-off of an obscure Chinese optical disc player firm, launches a high-end hi-fi product line. It’s not your normal hi-fi success story, but with each new product launch, the tale becomes more credible. The business now has its own matching DAC/preamp/headphone amp – in the very
