The 103R is a very good cartridge, I've listened to it after some highly praised cartridges and it always surprises. However, if you do the back and forth comparisons it sounds somewhat colored and has limitations in focus, fine detail, resolution of space etc which can lead to dissatisfaction.
Things get interesting though if you exchange the plastic body for wood or aluminium and have the stock Al/conical tip replaced with the Soundsmith ruby/line contact. Suddenly the 103R becomes very competitive in the above areas and retains its rightness of tone, solidity and musical engagement/expression.
It still won't have the ultimate finesse but it sure brings the music into the room.
