's single unit surround sound
bars have come a long way since the YSP-1
made its debut, and the company's latest entry, the YSP-4000, continues to up the ante, with 1080p HDMI compatibility, analog video upscaling to 1080i / 720p, XM Neural Surround compatibility, optional iPod dock, and a host of calibration modes, including one designed to make compressed audio sources sound better. Yamaha is being pretty coy with the frequency response numbers, suggesting that the YSP-4000 isn't an ass-shaking bass machine, but the 120W of power through six channels should provide plenty of clean sound for average TV and movie viewing. Available in October for $1,799.
