What Dreams May Come . . . The new Sony DVD Dream System is a bargain that's almost too good to be true. Far be it for me to expound the simplicity of a system's hookup. My home system is a wreck, with wires running hither and thither that I trip on almost daily. Oh what a tangled web I've woven! Yet my M&K THX speakers sound excellent, and my video system (a Panasonic DVD player and an RCA 36-inch TV) is a godsend. This is my main system, and my conscience would be partly cloudy with a slight chance of regret if I were to bring another system into my house (especially into my bedroom). But when Sony sent me the DVD Dream System (which is perfect for a second system), the trumpets sounded, and I suddenly found myself wearing a red cape and spandex outfit with the letters "EHW" scrawled across the front. I was, for a short while, Easy Hookup Woman (and I don't mean that lewdly, men in the audience).
