When you buy the multicomp they vary, since multicomp is a rebrand for Farnell group and so the supplier varies over time. Last time I bought them they had straight not curved edges unlike the original Naim feet, but they are just rubber feet, if you can hear a difference in rubber feet you are exceptional / deluded, delete as applicable. The only issue I have had with the multicomp is one or two seem to have bubbles inside the feet so they sag over time, just remove those ones and replace with another from the bag and move on, nothing to see here.
