Nah its not placebo, i listened to some mx brown videos on youtube and the filcos and qfrs all sounded like my stealth. The other brown keyboards sounded quite different. I had a qfr with blues and the clickiness overwhelmed the other keyboard sounds so i wouldnt call it comparable to the blues.
Eitherway, i just sold it to my friend and bought a fc660c topre board and a fc660m brown board. I really want a 60% board and Fwiw, the discrete arrow and fn key layer seems way more logical than the hhkb or pokerII
I like the Stealth edition but I don't notice any difference compared to other boards.. other than my QFS being Blues vs. Browns/Blacks on other boards lol.
Maybe just placebo effect? I don't know lol
