Of course my concern is those 'weak' channels that can't be made any better and hence a better tuner can pick it up vs a weaker one that cannot lock on the weak (edge-of-the-cliff) signal SNR. Yes, of course, I'll get the best antenna and amp as possible to get the best signal as it feeds into the tuner's coaxial input connection. Samsung is the one TV that you are looking for. If you have narrowed your choices down to Sony and Samsung, then your decision should be a no-brainer. The tuner for any reputable TV manufacturer should be more than adequate. However, sensitivity should not be your primary consideraton. If you have made the correct decisions about these issues, then tuner sensitivity may be a secondary or tertiary consideration. The whole point of this forum is to select antennas with sufficient gain, aim them properly, install pre-amplifiers to ensure sufficient signal strength at the end of long cable runs, and to install distribution amplifiers to ensure that each tuner receives sufficient signal. Hopefully, this Sony will be my last Sony TV until the company dramatically improves its quality. In my newest Sony-a 40' LCD flat panel-the digital tuner craps-out when the ambient temperature rises above 72 ☏. The tuner in another of my Sonys-a 24' flat face analog CRT-suffered dramatic loss in sensitivity. Of these, only my little 13' flat face CRT did not fail in one way or another. It is my understanding that Samsung manufacturers its own display panels.
