Sansui engineers have perfected the Straight DC circuitry of the AU-919 Integrated Stereo Amplifier right down to the very last superlative. Fastest rise time, highest slew rate, lowest TIM or Transient Intermodulation Distortion are not the least on the list. Then there are the words which describe its phono equalizer and flat amp - cleanest, quietest and definitely latest. Add the fact that the Diamond Differential DC circuit in the power amp and phono equalizer offers one of the widest frequency ranges ever achieved in audio - extending from zero Hz (DC) to an amazing supersonic high of 500,000Hz - and you have some of the reasons the AU-919 delivers the purest musical performance you've ever heard. The AU-919 isn't the cheapest integrated amp on the market, and at a modest 100 watts per channel, it isn't the most powerful. But we're convinced that for the serious audiophile who really cares about sound quality, and who is willing to make an investment in truly state-of-the-art equipment designed for nothing less than straight, uncolored, dynamic audio performance, the AU-919 deserves the most superlative of all - The Finest.
