Pre/Power Amplifiers

Is this a new twist on the CD player? Or yet another new variation on the DAC? Well, neither actually, for as that ‘Mk2’ suffix suggests, this is a revised version of ATC’s innovative CDA CD player/DAC/preamp combination, selling for £2950 and designed as the perfect partner for the company’s £3375 P2 power amplifier [HFN Mar ’17], or its range of active speakers.

The '70s was a time of great social change. At the beginning of the decade, black and white TVs, bicycles and outside toilets were the reality of life for many British people. But by the end of the '70s, most folks had colour TVs, family cars and swanky modern bathrooms – along with fitted kitchens, wall-to-wall carpeting and stereo systems in their homes. Although the music centre was the height of fashion, separates hi-fi was growing fast and many were willing to pay for serious equipment.

In the early days of hi-fi, the budget amplifier was usually considered an object of disdain, to be quickly upgraded as soon as funds allowed. More capable designs such as the NAD 3020 changed this view and by the late '70s improvements in component technology had made it possible to produce really good amplifiers that still could be sold for reasonable prices.

Headphones now rule – period – and as a vivid illustration of the current profusion of cans, I was staggered to see, at a store in Tokyo, a selection of something like 1500 headphones, and with plenty of high-end brands notable by their absence.

The late '60s provide an interesting choice of equipment for the vintage hi-fi enthusiast. The rapid development of high-quality transistor amplifiers during the period resulted in some intriguing models and the Sugden A21 is a fine example. Why? Because it was the first successful domestic hi-fi amp on the UK market to offer a fully transistorised implementation of Class A.
