Amplifiers

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

Tim de Paravicini, a bright former Lux designer who had previously worked with Antony at Michaelson and Austin, was the logical choice when Antony Michaelson needed his first Musical Fidelity integrated amplifier. Tim told me that the A1 started out as “a breadboard that I created for myself” in order to “replicate in transistors the

When you talk to Antony Michaelson about his vast product portfolio, there are a few designs in particular that he adores, one of which is the A1000. It’s a two-box design, with the first housing the amplifier and the second housing the power supply (11kg and 7kg respectively). Two sets of eight substantially heatsinked transistors,

Michael Maloney explains, “We were aiming to develop an amplifier that was well manufactured.” “When we started in the late 1970s, the quality of the components was fairly bad. In the signal path, they were still utilizing ancient carbon resistors and electrolytic capacitors, and the printed circuit boards were still Bakelite. We were among the

The original NAIT was the product that kicked off the ‘super integrated’ fad in the 1980s. Whereas “integrated” was formerly considered the poor relation of their high-end pre-power brethren, it became fashionable to opt for a high-quality one-box design with the same level of attention paid to internal component quality and circuit design. As a

Nytech’s iconic ‘Calculator Tuner Amplifier’ is virtually forgotten these days, although it made a big impact on the British hi-fi market when it was hot in the late 1970s. When it was first released in 1972, calculators were practically the width and depth of an LP record, and they, like the Nytech, were connected into

The UK hi-fi market was a different country in the mid-1970s. Pioneer, Sony, JVC, Hitachi, and Wharfedale dominated the inexpensive end of the market, while KEF, Quad, Tannoy, and Celestion dominated the higher end. Even at the top end, names like Linn and Naim had yet to enter the vernacular. Japanese manufacturers were booming, and
