Vintage

Sometimes you rediscover a classic once so far ahead of the curve that it cuts a dash to this day – and we're not just talking style but sound. Is this '80s amp one of them?

The 1980s was a decade of great change. Consumer products that had been the stuff of science fiction just 15 years earlier – digital watches, home computers, LaserDisc players – were now increasingly commonplace. The era had a dynamic, hedonistic feel, and it was now acceptable not just to have wealth but to show it.

The first solid-state Quad remains a classic of the genre Exemplifying all that was admirable in British hi-fi, the 33 preamp (£43) and 303 power amp (£55) were Quad’s first commercial solid-state offerings, the company having waited for the new-fangled transistor to settle down before embracing it in 1967. It was in many ways ‘a solid-state Quad 22’. Any previous customer would have immediately recognised the control locations, the flushmounted rotaries, the balance control under the volume control, the press buttons that also offered Quad’s unique, fully cancellable filter and tone controls and RIAA selectors. In size, the 303 and the Quad II power amps were nearly interchangeable.

Radford Electronics was set up in Bristol by Arthur Radford back in 1959. In some ways Radford was a late starter in the world of high fi delity, especially compared to Peter Walker of Quad or Harold Leak, and the electronics refl ect this. Indeed, Radford’s designs are often described as being the most ‘modern’ of vintage amplifiers. It was the Series Two amplifiers, soon changed to Series Three, that put Radford’s designs on the map, the Series 3 range comprising two monoblocks – the MA 15 and MA 25 – plus two stereo versions, the STA 15 and STA 25.

The ancestor of a modern classic still has much to commend it Author of a couple of 1967-8 HFN features comparing the operation of output stages in Class A and AB transistor amplifiers, Jim Sugden then owned a company producing lab and test equipment. But thanks to a collaboration with Richard Allan, a company making speakers based nearby in Yorkshire, the first Class A amplifier made by Sugden was marketed under the Richard Allan name. The A21 amplifier made its first public appearance at the ’68 London Audio Fair in London. A 10W-per-channel integrated, it sold for £52, like Leak’s Stereo 30.

Not only did this '80s amp claim to tackle distortion using the company's new 'Super Feedforward System', it was also priced to have mass appeal. How does it sound today?

When the Sansui AU-D33 integrated amplifier was launched in 1982, it had a lot to live up to. Its predecessor, the AU-317II from 1980 [HFN Jun '15], delivered the sort of performance one would expect from a manufacturer of specialist hi-fi, thanks to its well engineered DC-coupled circuitry. The company's 'All hi-fi, everything hi-fi' slogan set out a clear manifesto – no transistor radios, no coffee machines, just quality audio products.

This second-generation 16-bit machine hit the sweet spot for many when it came to sheer value for money, but does it make a bargain vintage buy? It's time to find out...

Has the 'perfect' CD player ever existed? While one model may boast the best transport, another the best DAC and yet another the most perfectly resolved ergonomics, so far I've yet to find all of these elements present in one machine. Sharp's DX-411H

This CD player from 1987 re-wrote the rules with its offer of 18-bit/8x oversampling while cutting few corners in the quality of its componentry. How will it sound today?

Back in the '70s, Japanese consumer electronics giants sold hi-fi based on so-called 'tech specs'. What began as a trend became an obsession, each new turntable being offered with lower claimed wow, flutter and rumble as 'proof' that it was superior to the one before. Indeed, some brands took to running ads highlighting the measured performance of components, with straplines to the effect of 'let the facts speak for themselves'. Back in hi-fi's boom years, such was the way of the world...
