The Beogram 4000’s motor unit, arm and cartridge were designed together to work as one optimised system. B&O had considered building a conventional turntable with a long arm but this was rejected in favour of tangential tracking, the Beogram 4000’s most famous feature. The basic structure comprised a die-cast tray that served as the basis for the slim and elegant plinth. This housed another casting, which formed a floating sub-chassis.

Naim Audio’s first product, the NAP 160 power amplifier, was introduced in 1971; the NAP 250 appeared in 1975. It was technically unusual in that it used a strictly regulated power supply, whereas the vast majority of power amplifiers, unlikely today, typically made do with an unregulated one. Arguably, the NAC 12 preamp was even more unusual than the NAP 250. In ultimate form it required a standalone external power supply – the SNAPS – at a time when such an arrangement was virtually unheard of.

The TA-1120 stereo amplifier was a step-ahead design which combined power, quality, reliability and compactness in a way that had not been seen before, but which in a few years would become ubiquitous across the ranges of Japan’s major hi-fi brands. In 1968 the original TA-1120 was replaced by the TA-1120A, as tested here, the addition of a headphone socket and the removal of a ‘safety’ indicator light being the only obvious external clues as to which model is which. Revisions were also made to the preamplifier circuit. The main selector lever gives a choice of phono 1 (MM) or tuner, along with a central position that selects a rotary control giving four further options, eg, mic, tape head, second MM turntable and line-level auxiliary input, which can be used to connect a CD player.

If you were just taking your first steps into the world of hi-fi in the early 1980s you’d give serious consideration to the Dual CS505. Often partnered with a NAD 3020 amp by the canny hi-fi buyer on a budget, these two components started many listeners on a path that would bring countless hours of enjoyment. In the 1960s and ’70s Dual occupied a similar place in the German market to BSR and Garrard in the UK, producing turntable units for music centres and combination units. Yet it retained audiophile credibility for the quality of its separate belt-drives, which sold well across Europe.

When the BC III was launched in 1973, Spendor’s ads described it as ‘An extension and refinement of theBC I and BC II’, while Thomas Heinitz, doyen of hi-fi consultants in those days, could not resist using the headline‘Hey, big Spendor’. The BC III was rooted in Spencer Hughes’ work at the BBC: he was part of the legendary BBC research team, working under both D E L Shorter and H D Harwood. It had an 8in driver with 40mm voice-coil, working in its own sealed chamber as a midrange unit while the 12in bass unit was reflex-loaded by a carefully designed port. The crossover point was 700Hz.
