Loose fitting power cord.



The power cord (Morrow) to my amp (Benchmark AHB2) is loose fitting.  It keeps falling out with the slightest movement.
Two questions.
Will that affect the ultimate SQ?
Is there any way to fix the problem short of getting a new cord?

Another option is to wedge a small wood or similar block under the cord housing to keep it in place
I've used the electrical tape method as well. If it ever needs to be removed, it can be a sticky mess. Try some heat shrink.
