I made my final decision by watching a bunch of you tube comparisons and listening to the sound clips on the Matias site. In the end, I chose the slightly lower pitched clicks of the Das Keyboard over the runner up, the Matias tactile pro, whose charms were many, but whose clicks sounded a bit too chirpy for my taste. Like, what the fk are you so happy about, keyboard?
So yeah, I made my decision blind.
Das Keyboard arrived today. I purchased a refurb direct and it looks to be brand new. No obvious flaws, and was just over $100 shipped. So far so good. My husband can hear it from the next room, I guess I'll see how his cumulative annoyance is shaping up by next week.
But first impression? Totally love it.
