Samsung LN52A750 LCD TV Comparisons & Conclusion
The most obvious comparison to make is with the Sony KDL-52XBR4. As much as I like that TV, I prefer the Samsung with its better blacks, sharper standard-def detail, better 120Hz frame interpolation, one more HDMI input, and better menu system. And the Samsung is $800 less than the Sony to boot, making it a better value. Both have very wide bezels, so you need to take that into account either way.
If $3200 is still too much for you, consider the LN52A650 ($3000) or LN52A550 ($2400). The LN52A650 is nearly identical to the 750, except that it has no DLNA capabilities, internal content, or integrated woofer, and WiseLink can play only photos and music (no video) from a USB storage device. The price difference between the 650 and 750 is minimal, so if you can afford $3000, I'd probably advise spending the extra $200 to get the full boat.
The 550 is 60Hz instead of 120Hz, it has lower contrast, and it has no InfoLink, WiseLink, internal content, or DLNA. Also, its screen isn't as shiny as the 650/750 screen, which could be a plus for some. If you don't care about the connectivity features, you can save a lot of scratch, but the picture is most likely not as punchy, and motion detail is bound to be less sharp than either of the higher-end models.
Samsung has come a long way from the days of being a cheapie brand, and the LN52A750 proves it in spades. Gorgeous colors, exquisite detail, great blacks, excellent shadow detail, exceptional processing, tons of useful features, and a reasonable price—what's not to love?
