Schiit Vidar 2 Stereo Amplifier Review

[375HP2482]

The first Class-D amplifier was invented by British scientist Alec Reeves in the 1950s and was first called by that name in 1955. The first commercial product was a kit module called the X-10 released by Sinclair Radionics in 1964

In the 80s Bose implemented an offline-powered Class-D mounted inside their Bose 800 commercial speaker. A bit noisy compared to modern units.

I imagine by now someone has utilized an offline Class-D amplifier inside their subwoofer.

FYI & FWIW

Class D (PWM) amplifier archaeology

So, I'm a scientist, not a historian, but I am still fascinated by history... and I crave context. You all know that the late Sir Clive Sinclair is regarded as the purveyor of the first significant PWM amplifier products for audio. https://www.vintage-radio.net/forum/showthread.php?t=81139 A...
