Hi Steve,
I had the KEF 107 & 105/3 many years ago. I do remember there was a wiry element to the tweeter. I suspect some of it was the equipment I used at the time (1980s). They did need power.
I had some caps in the crossover of the 105 split & leak, which made my power amp at the time go into a safety mode. The dealer very kindly replaced these caps with another type (I cannot remember which manufacturer) and I found the speaker became much sweeter & better.
It may be worth having a look in that area with a good modern cap. Have a look at some mundorf silver in oil types if the values are not too big to make it expensive. If the cap values are large & expensive try a bypass cap. I bet you would be surprised at the difference.
I never really found a sound I loved with KEF although at the time it was impressive, probably due to the bass.
I moved away from KEF after that (to TDL), so I don't know the later speakers. I hope this helps.
