I have a Topre and various cherry reds and browns. The Topre actually isn't the best for me and I don't use it much, so I don't think I have a bias towards it, but I can say that the difference in how it feels is not subtle.
Not the same. I honestly cannot hear differences between audiophile quality headphones or interconnects.
The typing experience of Topres' is noticeable whether you come from domes or mechanical keyboards. They feel in-between. I have arthritis in my right pinky. A 35g topre keyboard is perfect. (I also tried 35g mechanical switches but it did not feel as smooth).
Interesting, maybe I have a heavier Topre. Sore finger joints are why I went mech, which solved the issue once I learned to type without bottoming out. That ended up feeling pretty fast, too.
With my Topre, I wasn't able to do that, and even though it feels pretty cushiony at the bottom it still left me with some soreness. But maybe it's just too heavy.
