What's your favorite boutique speaker maker

Joesph Audio..

+1 for Joesph Audio

Perspective 2’s are a perfect fit for my medium sized room. Tone, texture, detail, dynamics and scale are magnificent.  Build quality is top notch and Jeff is a really nice person too. 

The first company that came to my mind is Merlin speakers. No new production since the owner passed away but Rich Brkich of Signature Sound offers full support, like new refurbished TSM monitors and VSM towers as well as upgrading any model to the most recent level.

Merlin is one of the few speakers that can match the speed, resolution and tonal purity of ATC, my favorite brand (not boutique).

Agree with vdotman completely. Fuselier speakers from the early 80's were something special. Wish I still had my 3.3s which I loved dearly.
John Fuselier was also a commercial airline pilot I believe...

Amphion, this very well built speakers from Finland 
has a great time aligned wave guide tweeter that not only is voiced 
to blend in the vast majority of rooms  ,its tweeter Xover at 1600 kHz is totally out of the critical 2-3 kHz region, most are not , and the balanced rear 
Bass radiator is far better then a port especially for the mid band 
much lower Accurate Bass especially for stand mount speakers  ,also no port noise in the midband, and 
all excellent quality Seas drivers from Norway. a very minimal Xover,  many Recordings studios now are using them for their 
accuracy and musicality, and reasonable cost.
