Driving to Vegas, I always stop in Baker, California, gateway to Death Valley and home of the world's tallest thermometer—134 feet, representing the highest recorded temperature in the US of 134 degrees in 1913. In this night shot, the thermometer is reflected in the 2009 Lincoln MKS that THX loaned me for the trip to check out the THX-certified sound system therein. Unlike past systems, this one can play multichannel DVD-Audio and even DVD video on the in-dash screen (as long as the car parked). Just like past systems, however, this one is quite boomy in the bass, and the only EQ controls are bass and treble. I got it sounding pretty good, especially on Donald Fagen's <I>Nightfly</I> DVD-A, though road noise—even in a car as quiet as this—can wreak havoc on something with a wide dynamic range like Stravinsky's <I>Firebird</I>.
