Several of the 3D projectors at CEDIA use passive-polarized glasses, which means they require a special silver screen to preserve the polarization of the light from the projector. However, such screens are not ideal for 2D images—their high gain results in hot spots and other issues that degrade the quality of 2D content. Stewart Filmscreen has come up with an ingenious solution—the Daily Dual, which consists of a fixed silver screen and a retractable white screen that covers the silver screen when displaying 2D material. It ain't cheap—a 132x74-inch system will set you back $15,000—but if you prefer polarized 3D projection as I am starting to, it's clearly the best way to go.

Bob Farinelli, president and CTO of Elan Home Systems, discusses what people need to think about when considering a whole-house A/V system; distributing audio via line level, speaker level, and S/PDIF digital; long HDMI runs; wired vs. WiFi IP distribution; wall-mounted keypads vs handheld remotes; eliminating audio delay in "party mode"; and answers to chat-room questions.

With a name like Okki Nokki, it has to be good! This German company has come up with what it calls "the VIP of record-cleaning machines." You spread the included cleaning fluid on a vinyl record and attach the aluminum vacuum arm, which sucks up the fluid and, presumably, any dirt or dust on the surface. The RCM also comes with a goat-hair brush for $500 ($50 more for the clear dust cover). Michael Fremer should definitely hear about this!

New from REL is the G1 subwoofer ($4000), which sports a 12-inch carbon-fiber cone in a sealed, curved cabinet with a 700W class-AB amp.
