| The Bottom Line | CNET did not review the Sony KDL-52XBR4 HDTV, but we did review a smaller model in the series. | Although not quite as impressive as the best plasmas, the 46-inch Sony KDL-46XBR4 outperforms any flat-panel LCD we've tested so far. | Sony's high-end KDL-XBR9 series of LCD TV offers a bundle of extras and solid picture quality, but the price will turn off most buyers. | Although not quite the best HDTV we've tested so far, the wallet-busting, LED-powered Sony KDL-55XBR8 comes mighty close. | The Samsung LNB750 series can't beat the picture quality of the best plasmas and LED-based LCDs, but for a conventional LCD, it's one of the best we've tested. |
