ven on a dreary April day, with rain blurring the horizon and the sky a menacing gray, the picturesque town of Greenwich, Conn., looks as inviting as a Norman Rockwell picture. The lus h landscape beckons with dense green lawns, leafless trees sprouting pink and white blossoms, and an elegant, old-style home nestled on each lot.

For at least one of those homes, the exterior style is deceptive. Although Yankees pitcher David Cone and his wife Lynn love classic details like the wood paneling and antique furniture in their English manor-style home, their awe-inspiring $250,000 sound , video, lighting and security system is the real show stopper.

An 80-in. screen dominates the media room downstairs, with a double rack of audio equipment, ceiling-mounted projector and gargantuan speakers providing backup. Lynn, an interior decorator, chose the antique oak paneling and cozy maroon couch that give th e room its warmth. But her sense of style may have worked too well. In another new home they will move to later this year, she'll put the media room just off the kitchen--to keep David from disappearing into some remote corner of the house to watch action movies.

Lynn prefers the full-house sound to the pleasures of the big screen. "It makes such a difference to be able to play music anywhere in the house," says Lynn, who had speakers installed in the steam room, her dressing room and even the shower. Their instal ler, Mark Risi of Performance Imaging, was careful to modify the equipment for each room, choosing a powerful subwoofer and amplifiers for the gym and waterproof speakers for the pool area.

While clearly a fan, Lynn is not star-struck by the latest technology. She remains skeptical, for example, of the automated lighting that controls groups of lights with a single button. "I don't see why you can't just flip on a light switch instead," she says. That old-fashioned sense may explain her knack for making a state-of-the-art home feel like a cozy country estate.
