The LN46A550 has a 30,000:1 contrast ratio while the LN46A540 has a 35,000:1 contrast ratio. That is the only difference I noticed.

THe description said series 500; mine is a 530. I would probably look for a series 600.

The 55 has a motion sensor, the 50 does not have a motion sensor. The 50 will light up when there is not enough light. The 55 will light up only when there is not enough light and it senses a motion or movement.

The 55" supports 2.5 & 5GHz 802.11n but not the newest 802.11ac standard. I would assume the 46" is the same.

According to the Sonicare website the difference between the 9500 (9000 series) and the 7500 (7000 series) is minimal. The 9500 includes the custom care system and programmable quadpacer. The Custom Care System essentially comes down to the inclusion of an extra compact brush. The programmable quadpacer allows the user to change the intervals and overall time of the brushing cycle. The 9500 includes both a standard and compact brush (as stated above) while the 7500 only includes the standard brush. Finally, the 9500 includes a deluxe travel bag, while the 7500 includes a standard travel bag.

If that's all than it's not worth the extra price. The LN37A550 costs less than the LN32A65. I might just look at the 37A550 instead.

The V550 is the latest model and is replacing the V500...The V600 is an existing model, been out about a year...

The A630 has 40000 dynamic resolution and the A550 has 30000 dynamic resolution. The higher resolution supposedly gives it better PQ but I don't know how they compare watching them side by side. Other then the 120Hz I don't know what other differences they have. If you go to Samsung.com you can pull them both up and compare them.

The 861 is an improved model over the 860. It adjusts more easily for depth and placement, resulting in better alignment of dovetails.It is a better product than the 860... if you were to buy the 860, you will soon wish that you had paid extra for the 861, unless you're a very experienced router guy.

I don't know what the difference is. All I know is that the 6301 only functioned for about 4 weeks. After that they just stopped communicating with each other.

Another, for gamers major, difference is the fact that the B530 and B550 differ in which computer resolutions are supported. The B530 does NOT have computer support for the tv's native resolution. The very reason I wouldn't even consider the B530.

The 4600 is the latest model. Difference that I can tell is that the 4600 has three specific levels to choose the amount of vapor produced. The 4500 has an infinitely variable controller. I have had the 4500 and now have the 4600. Of the two, I prefer the 4500 vapor controller because in my application I don't want much vapor. On the other hand, it is nice to have three specific levels. Another difference is the form factor. The 4600 is a little higher and not as deep as the 4500. Either way you cannot go wrong.

They look the same, but inside have some differencies: S50 Bluray, 4GB RAM, 500 Hard Disk, Win 7 and is more expensive than S55. I recommend S55; a relevant difference I see is the bluray player and that isn't more important than the processor or the hard disk.
