Steve Jobs may have moved on, but Apple's quickly returned to shaking up the music and movie industries in the good old-fashioned way: with beta releases and rumors.

Cambridge Audio is a British electronics maker with a long-running dedication to serious audio (minus the silly-expensive audiophile pricing) and a long-running commitment to quality digital playback. So, when the company first previewed a network music player in late 2010, it got my attention.

My review sample of the Harman Kardon BDS 5 Blu-ray receiver arrived shortly after the death of Dr. Sidney Harman. Let’s take a moment to celebrate the life of one of the audio industry’s founding fathers. Harman and partner Bernard Kardon pioneered the A/V receiver category in 1954 with the Festival D1000, the first audio product to combine the functions of a mono power amp, preamp, and radio tuner. The stereo version, the Festival TA230, arrived shortly afterward. By the time Harman retired in 2008, A/V receivers were wearing his name. Harman International eventually became an audio empire, not only continuing the Harman Kardon brand, but also encompassing JBL, Infinity, Lexicon, Revel, Mark Levinson, and others. Harman was a renaissance man: an activist, philanthropist, professor, and public servant, the quintessential tough businessman with a heart of gold.
