Amplifiers

Few would deny that a well-built valve amplifier can produce excellent sound, but the problem is that they aren’t as user-friendly as solid-state devices – at least not to the uninitiated. While you can buy any sensible transistor integrated, plug it in, and expect a reasonable sound regardless of your system, thermionic valves aren’t exactly […]

The NAD 3020 was undoubtedly the finest hi-fi success story ever reported at the start of the 1980s. This small integrated amplifier had a tremendous impact on the cheap hi-fi market, and for good reason. The infant New Acoustic Dimension, introduced in 1979 and priced – for a brief, fleeting moment – £59, sounded significantly

Sugden has no introduction; everyone with even a passing interest in audiophilia is familiar with the A21 series of English amplifiers, which began with an 11 watt solid-state bipolar integrated amplifier in the mid-1960s. The A21a became a nineties benchmark; a specialist product that promised clarity at the expense of all else… It was produced

Let’s be honest: Bang & Olufsen’s philosophy isn’t ‘sound first, everything else second.’ However, if we’re being honest, it’s difficult to say the same about the majority of so-called “true hi-fi” makers, to whom we serious audiophiles happily grant house room. Can you honestly state that the ordinary Arcam is solely concerned with sound, ignoring

Do you recall the decade of the 1980s? The only substantial amplification at the start of the decade came in two boxes. You’d have to buy two, one marked ‘pre’ and the other marked ‘power’, whether it was Naim, Meridian, Exposure, or Quad. Then, in 1984, Naim Audio shocked the hi-fi world with the introduction

One of the most iconic names in British hi-fi, Harold Joseph Leak founded this now-defunct company in London in 1934, later selling it to the Rank Organisation in January 1969, when its fortunes began to falter. Between these times, and particularly in the 1950s and 1960s, the brand was known for high-quality amplifiers, radio tuners,

It’s not just about listening to music when it comes to hi-fi. Of course, its primary role is to sound good, but it also serves an aesthetic purpose. There’s no shortage of gear that excels at one of these functions, but it’s unusual to find something that excels at both, such as Lecson’s famed AC1/AP3

Most amplifiers from the 1980s weren’t anything to write home about, especially the gadget-laden behemoths. But Marantz’s flagship was unique – a hefty 25kg integrated that cost £1,000 and featured the company’s odd ‘Quarter-A’ technology, which handled lower-level signals up to a quarter of the maximum power output in pure Class A. However, when the

Passive preamps have one advantage: Their short signal lines and lack of circuit complexity result in a clear, detailed sound. They aren’t, however, a cure-all for the problem of controlling your source. They have traditionally depended on resistive networks selected via a switch or rotary variable resistors, which can result in significant impedance mismatches at

When NAD’s 3020 initially arrived in the early 1980s, it blew past all other cheap integrateds, as well as innumerable amps costing much over twice as much. The hi-fi market cried out for something with a comparable astonishing mix of price and performance, but at a higher level, over the next few years. Then, in
