The D/AC-1500 Digital-to-Analog Converter has been designed to extract greater musical detail from any digital source. If you are using it to upgrade your CD player you will find the D/AC-1500 makes a world of improvement. You will enjoy more of the warmth and depth that has previously been associated only with the finest analog sources. The D/AC-1500 sets new perfonnance standards at its modest price. Its highest quality hand-selected component parts, triple power supplies, high current drive analog stages, plus hookup and operating flexibility are far superior to al1 but the few most expensive D-A converters.
