Move over, Nautilus - there's a new flagship at B&W, and it's the Signature 800. But since it stands 47 inches tall and weighs 275 pounds, "dreadnought" might be a more appropriate term. The vented enclosure houses two 10-inch paper/Kevlar woofers. A sphere embedded in the top of the cabinet holds a 6-inch Kevlar midrange driver, while the tapered enclosure of a 1-inch metal-dome Nautilus tweeter sits at the summit. Its rated frequency response is 37 Hz to 23 kHz ±2 dB, sensitivity 91 dB. A cast-aluminum plinth serves as the cabinet base and houses the crossover network. The finish is gray tiger's-eye wood veneer with black leather trim. Price: $20,000 a pair. 800-370-3740, www.bwspeakers.com
The MP360 portable MP3 player from Zenith starts you off with two 32-megabyte SmartMedia cards, each of which can store about half an hour of music at the de facto MP3 standard of 128 kilobits per second.

Accessories abound: earphones, a wired remote control, a rechargeable battery, and a battery charger are all included. One charge is said to last 4 1/2 hours. Price: $230. 847-391-7000, www.zenith.com
