Same! Got my Canterbury GR just over 4 years ago. I upgraded from the SE, and was initially depressed how blonde and dry the new GR wood looked next to the 5-year old SE. Now the GR wood looks like my old SE did. It only takes a few wax applications over the years, but this seems to help a lot.
Incidentally I just re-bought my old SE, from the guy I sold them to. Man is their wood pretty now. Got spare tweeter sets (the most likely part to have issues) for those SE and the GR - with so much doubt around what’s happening to Tannoy, I’m ensuring I’ll at least have a lifetime supply 😂
I just buy a cheap pack of 100% cotton white t-shirts from WalMart for the wax application. A proper applicator might help for a smooth and even finish, though.
