I second and third everything that has been said here, but will add that a simple lower leg service (if it hasn't been done in a while) can really improve small bump sensitivity.
Also, less beefy fork chassis can result in bind between the uppers and lowers even in the low speed chatter decreasing small bump compliance. Modern super-slack head angles on trail and enduro bikes make telescopic forks work better as they are orientated more towards a plane that minimises bind.
So another factor could be head angle on your bike (don't know if that is the case, no idea what you ride).
Perhaps it's time for 59° degree head angle on all trail/enduro rigs.
Just get the new Fox 38.
Or the Trust Performance linkage fork, cheap at £2500.
