When designing any turntable, ensuring that it maintains the correct and consistent speed is of paramount importance. Numerous techniques have been tried over the years, some with greater success than others. The Philips GA 202 Electronic turntable reviewed here was one of the first popular models to feature a motor controlled by an electronic servo, bringing easy operation and improved performance. This was the deck's key feature, but there were other striking aspects to the design.

The friend who helped me unload these three AVID Hi-Fi boxes – one for each Reference Four speaker, at £20,000 a pair, plus one for the included (and very hefty) stands – thought he'd nailed it. 'What are these for, then?' he asked, 'heavy metal music?'. He wasn't far off the truth for while most speakers do very nicely indeed with variations on the wooden box theme, the Reference Fours use all-alloy cabinets, with panels up to 15mm-thick, sitting on six 'risers' attached to a thick alloy baseplate. Hence why each of these relatively compact speakers, at just under 37cm tall, weighs 25kg.

The Chord Electronics Anni, selling for £1195, isn't the company's first compact amplifier – that honour goes to the £2900 TToby [HFN Feb '17], designed as a partner for the Hugo TT 2 DAC/pre/headphone amp [HFN Dec '15]. But the Anni is smaller, at just 16cm wide and 4.25cm tall, much lighter at 625g, and conceptually different from the TToby.

Any mention of Dual turntables usually brings one of the many incarnations of the company's CS 505 to mind. The original '505 was a typical Dual design, taking its cue from the basic turntables that had been around since the 1950s by being built on a sprung-steel plate. It was a budget deck, which sold mainly to those looking to take their first step on the audiophile ladder. But Dual made more ambitious models too.
