If your input is not within the specified limits for the tuner it's just not
fair to say it's not as good. "Not as good with X input level" might be
accurate, but if it's not within the spec it's meaningless.
If a simple attenuator produces better results, why complain?
The more channels a cable system adds, the harder it gets to maintain levels
high enough to get a good signal to noise, and still low enough to minimize
third-order products. The window between those two points gets smaller.
