I did a little experiment on my receiver today.
When it worked it's best, I used Harry's Homebrew power amplifier (from 3 transistors) with the bootstrapping enabled, and the two diodes set to 1N4007's. The URL to the amplifier is at:

When I changed them to only 1 1N4148 diode, I lose remote stations.
So I took it upon myself to CUT the diode, making that section an open circuit. So what happens? the volume is louder, which is nice, the remote station tries to pull itself in while mixing with a local station, but it fails. If only I can separate the two stations, then I would be happy.
I'm wondering if I should go along with 3 or 4 diodes in series, or use my 1 fat 1N5408 diode instead.
It seems that the power amplifier is what now determines the quality and the distortion of the output.
If all else fails, I might end up reverting back to the 1N4007's.
