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.

Back in the 1980s, when the UK hi-fi scene began, belatedly, to experience products from places more exotic than Glasgow, Bradford, Huntingdon, Maidstone and Salisbury – ones that didn't say 'Made in Japan' on them – the USA provided a stream of surprises, one of the most memorable being Magneplanar loudspeakers. For most audiophiles, isodynamic drivers were something you found in a left-field Wharfedale headphone of the early 1970s, yet here were full-range panel speakers using essentially the same technology.

The Progression Stereo amplifier is built around a dual-wound 1400VA toroidal transformer coupled to 400,000µF of power supply storage capacitance that feeds no fewer than 48 power transistors – 24 per channel. On paper this is said to generate 300W/8ohm, doubling into 4ohm [see PM’s Lab Report]. And it’s yours for roughly half the price of a pair of the company’s Progression Monoblocks [HFN Jun ’17].
