The only one of those that might be considered boutique is Daedalus, and even that’s borderline.

Have cycled through tons of speakers. Now I swear by Dennis Murphy’s Phil-3. Mine are in beautiful red maple veneer. My cousing got a pair in curly maple blue. Cabinets were done by the great Jim Salk of Salksound. Dennis and Jim work together on projects. Salksound offers the fantastic BMRs (I have a pair).

These go quite low and they are superb and I am pretty much done.Since I can’t leave things alone, just for the heck of it I added two SVS SB2000 subwoofers, one for each channel. Dennis suggested crossing over to the subs at 80Hz and wow!! I just can’t see needing anything better.

Totally agree, hard to define boutique. Personally I'm a big fan of Rosso Fiorentino. Certainly not well known, but I don't know if it's considered boutique either. And to an extent would could say anything ultra high end (say Rockport) is boutique because you can really only get their gear via their dealers... aka audio boutiques. By that measure brands like Tekton and Zu are decidedly not boutique if we're being technical.
