The word 'autochanger' strikes fear into the hearts of LP listeners, bringing thoughts of clanking levers, heavyweight arms and stacks of records slamming on top of each other. The situation is more favourable when it comes to CD. Most players handle discs mechanically anyway, and so only a relatively straightforward extension to the mechanism is needed to allow more than one disc to be loaded at a time.

It's always intriguing to see how a company reacts to the realisation that a technology it has championed is reaching its sell-by date. This was the situation faced by Yamaha in the late 1970s. Since the middle of that decade, its top-end products had made use of Jun-ichi Nishizawa's Static Induction Transistor – more commonly known as the VFET – to great effect. This led to the development of designs such as the B-1 and B-2 power amplifiers, and C-1 preamplifier, all of which are still held in high regard.

Most hi-fi enthusiasts know how many watts their amplifier can produce, but does that figure tell the whole story? In the early '80s, Harman Kardon's HCC (High Current Capability) range of integrated amplifiers gave listeners another number to think about, which was how much current an amplifier was able to source.

The argument for building a system using components from different manufacturers because 'no company is good at everything' is a good one – up to a point. Conversely, the Japanese heavyweights such as Sony, Technics and JVC were once able to put together a fairly convincing complete package, as could Philips (on a good day!).

The products we usually seek to feature in our Vintage Review pages are those that were among the first to introduce a new format, function, level of performance or design theme. However, this month our subject is the Technics SL-J33 turntable of 1986, one of the last in a series that had a footprint the size of an LP sleeve, which began with the SL-10 [HFN Apr '19].

One challenge faced by those designing hi-fi in the high-tech 1980s was how to re-package the LP in a way that would ensure it remained of interest to consumers in a future that was clearly going digital. Released in late 1979, the Technics SL-10 turntable [HFN Apr '19], with its parallel tracking, optical position sensing and slick packaging was one of the first components to address this issue seriously.

While not a name often associated with early CD players, Kenwood was not lacking in ambition with its first entry into the field. Rather than test the market with a quiet offering buried deep in the backwaters of its catalogue, in 1983 the company added the L-03DP CD player to its range of top-line components.
