Whest Audio’s PS.30RDT was released in 2009 as a near descendant of the company’s flagship MC REF V, and it cost a whopping £2,799 when new. It comes in a single 430x280x72mm box with a Whest MC REF V Hybrid filter and an ultra low noise bipolar opamp DIP8 chip severely biased towards Class A. […]

Page after page of criticism and opinion – sometimes dressed up as fact, sometimes not – on how bad Japanese amplifiers were in 1980 could be found in any British hi-fi journal. They claimed this was especially true in the inexpensive sector, where all of their “frills” meant money wasn’t spent on items that would

Sony amplifiers had abandoned their unique but unstable V-FET output transistors by 1979, and were inventing in new ways – the goal was to bring an interesting twist to a standard design. As a result, Sony engineers placed the power transistors on the main circuit board from the center of the new TA-F range upwards

In 2016, this £1,250 integrated amplifier was released. It features five line inputs, a moving magnet phono stage, and aptX wireless Bluetooth, however it lacks DAC functionality. Aside from the Bluetooth, which is unabashedly a convenience feature, this amplifier looks a lot like something from the 1980s. It’s a big, Class AB thug with a

When it was first released in 2010, this dual mono integrated Class AB powerhouse (claiming 125W into 8 Ohms) was a costly piece of kit at £5,750. It’s solidly constructed and polished, but it’s not a £6,000 Japanese device — there’s no luxuriously covered brushed aluminium, astonishing shutlines, or a plethora of elegantly performing buttons.

The golden period of Japanese hi-fi was probably from 1976 to 1981, when the Yen was severely undervalued on international markets, allowing Japanese manufacturers to produce items that Western businesses simply couldn’t match. Despite the fact that Japanese hi-fi became linked with value, all of the main brands had high-end sections. The items that came

Hitachi’s discovery and production of MOSFETs (Metal Oxide Silicon Field Effect Transistor) had a major role in the hi-fi world that was just around the corner in the mid-1970s. The world had only been in solid-state for fifteen years and was still on a long and steep learning curve. However, Hitachi’s new power MOSFET output

Tube amplification was viewed as an extreme niche in hi-fi in the late 1990s, similar to how most petrolheads thought of kit cars (i.e. “interesting, but not for me”). So maybe it’s a sign of the times that we’re suddenly getting more new valve items than transistor products. Icon Audio happened to be in the

This was a superb affordable audiophile valve amplifier that was launched in 2012 for the princely sum of £1,700. “The original Stereo 40 was born in 2000, and was at the heart of what we do, top quality amplifiers at a reasonable price,” said chief designer David Shaw. This is a jumble of ideas with

The famous 845 power triode began life as a radio transmitting vacuum tube, with a physically huge anode dissipation of 75 watts and an anode voltage of 1,250V. Because the thoriated tungsten filament – which shined like a lightbulb – was powered at 10 Volts and 3.25 Amps, any transmitter running a large number of
