Of course leaving your system as is instead of chasing a slightly "different" at best presentation is also an option (sometimes)
Kimber cables are always musical and it doesn't even matter which level. Listening to a pair of Kimber Hero ICs as we speak and they sound just as good as anything I have had in the system overall.
There is no "better" because there is no gauge to go by. Better is only what sounds better to your ears but that is often just "different" at best if there is a difference at all.
Just my opinion on the open question and it will not cost you anything.
