The Digital Projection Titan RP97 rear-projection system is billed as a "full plasma replacement system." Its three-chip DLP, 10,000-lumen rear projector can be mounted in a small space, and the image is unaffected by even bright light. The $99,995 cost seems high until you price plasma displays of similar size.

Oppo Digital showed a prototype Blu-ray player that is scheduled to hit the market sometime in the winter. In addition to playing Blu-ray Discs, the BDP-83, as it's now called, will also upscale standard DVDs, and play audio CDs and SACDs. DVD-A support is still up in the air. Also up in the air is the price, which will be "no more than $800" according to a company spokesperson. The player has 1GB of onboard memory and a USB input.

JL Audio is best known for its subwoofers, but the new Primacy X3 speaker may change that. This is a three-way, powered speaker that uses DSP-controlled crossovers and 1000 watts of internal amplification.

Also new from JL Audio is the Fathom IWS in-wall subwoofer, which uses an external controller/amplifier. One controller/amplifier, one driver, one enclosure and one grille cost $4500.
