The very first amplifier I bought was a Harman Kardon PC-200, aka The Prelude. It was a 10Wpc integrated, but I chose it over the competition for some of the same reasons that the HK 990 has appealed to me. Almost all amps back in the1960s had a plain cake-pan chassis with tubes, capacitors, and transformers studding the top. Integrated amps had the standard four knobs on the front for input selection, volume, bass, and treble. The HK PC-200 had an enclosed black chassis cage that formed a graceful cowl over the brushed-copper front panel and the six matte-black knobs: for Input selection (with three phono turnover settings), Volume, Bass, Treble, Loudness contour, and Treble rolloff. In addition, it had a Rumble Filter switch. The PC-200 was not only more beautiful than the rest of the push-pull competition powered by EL84 tubes, it also had more useful features. (Take that, you fans of the Grommes Little Jewel
!). Over the decades, H/K products have always been stylish and innovative, but in today's fractured marketing world, most such creative energies are applied to audio/video receivers and lifestyle products.
