So over the years I’ve used the banana connector adapters
recommended by inhifiman and kalili on the following amplifiers with great
success: McIntosh MC30, Audio Research D-40, D-70, D-115B, Classic 30 and
Classic 60. The speaker wires used were either factory terminated Audioquest or
Kimber Kable. Zero issues in terms of poor connection, banana connector falling
out, shorts, oxidation, end of the world, etc.
As already suggested as well, do not try and bend or modify the barrier strips. They can/do break easily.
