The advantages of using separate pre and power amplifiers over an integrated is a discussion that can still occupy audiophiles for hours. What was almost a necessity in the valve era became less technically significant once transistors were established, a quality solid-state preamp circuit being undemanding in terms of space and power.

Everyone old enough to remember, talks about the 1970s as the golden age of British hi-fi. That's certainly true in one respect, because what was a niche – often do-it-yourself hobby – went completely mainstream, to the point where the third most expensive consumer item, after a house and a car, was a stereo.

The law of diminishing returns was perhaps never more evident than when the CD player arrived in the early '80s. As more machines came to market in the years that followed, all but the crudest would offer a level of perfection unthinkable to the majority of audiophiles in the 1970s.

It's not unusual for a successful hi-fi product to be updated with mild revisions during its lifetime. Often the changes are minimal: a tidied-up fascia to match a new model added elsewhere in the range, or an extra function or minor circuit redesign. This was certainly not the case with the Leak Stereo 30 Plus amplifier of 1969, which replaced the Stereo 30 [HFN Oct '10] first seen in 1963. Side by side the two looked much the same, but inside the 30 Plus was all new in order to take advantage of improved technology.

The CD-73 is surely one of the best loved and best remembered of the first generation of CD players. With its eye-catching looks, it stood out among a sea of bland black boxes. Usually it would have been difficult for a company of Marantz's standing to come up with a fully engineered model so quickly, but having recently secured the backing of Philips, it was able to release not one but two class-leading CD players for the opening 1983 season.
