Not that I'm aware of. Stereo image is a function of separation between
channels. Any competent stereo amplifier has more than 50-60dB separation at
all audio frequencies, so won't affect the stereo image. Remember that
pick-up cartridges manage good stereo imaging, and few have more and 20-25dB
separation at mid frequencies, much less at the frequency extremes.

Is there a known connection?

Is there some reason to believe that amplifiers have an effect on the
stereo
image or is that just wishful thinking on the part of some audiophiles?

If there is a connection, what would it be, is it measurable?
