Not with any specific amplifiers for AM/FM broadcast. I do have some experience with high end pre amplifiers used in commercial applications. One thing to consider is that the typical cheap inline amplifier is going to amplify the noise as well. I would raise my antenna, if possible, before I added an amplifier. Typically in a commercial radio installation, such as cell phone tower or VHF/UHF repeater site, the receive amplifier is at the top of the tower close to the antenna. The purpose is to boost the signal some before the cable loss of plumbing it down the tower. These could be sites with 500' of coaxial cable. Even large 1.5" hardline cable has significant loss at 1-3GHz. These amplifiers are state of the art and usually have only about 15db of gain. They also boost the noise floor some. If I were looking to install an amplifier, I would look for one that mounted at the antenna and had moderate gain ( +20db or less). Something that could be turned off and on as you needed it to would be nice. Somebody is bound to make decent amplifiers, but if it's possible to raise the antenna, that would be a bigger improvement. Just my .02 cents worth of opinion. There's probably someone on here that is more familiar with actual performance.
