Logitech's Romer switch's are pretty quiet IMO, mind you I find them comparable to a membrane feel.
Orings will kill alot of that bottoming out sound, literally just finished installing a set of orings on my Asus Flare KB with Browns. way quieter.
I have done MX reds, blues, browns, silvers ( way too touchy for me )
Romers and 2 cheapo blue sets.
I love the feel of blues but same as you wife hates them.
TBH browns with a nice set of silicone orings, rubber tends to harden after time, are my favorites outside of blues.
EDIT: Forgot about Blacks moocow, TYVM, again have a cheapo set in a Chinese KB, they are dead silent, that said hated the keyboard so off to the spare parts room it went.
