Although it is ROCCAT's first keyboard to use optical switches, the Vulcan TKL Pro feels like a product that has been around for ages. Both the hardware and software are excellent, although not perfect yet. The only thing that some people will enjoy at first sight is probably the price.

I recommend trying a hot swappable keyboard and fitting it with something like gazzew u4's or bobagums.
This looks like yet another mech keyboard equivalent of the Sony WH-1000XM4's for audiophiles.
A very interesting suggestion. Care to elaborate and mention some brands/stores to get the parts?
