What's your favorite boutique speaker maker

Me!

I would add George Short of north creek music systems sadly he closed up his business. He moved on to Wisdom audio as chief designer. Over the life of north creek he sold thousands of kits ,fully built , crossover parts and licensing of designs to other manufacturers. I own his manifest speaker a very fine design . But he had many designs from floor standers to book shelf. Marc

...Not sure if this company is a 'boutique speaker maker', but the German company Manger Audio manufactures some (really!) impressive 'Speakers, their flagship S1 active floorstanders, which use a novel architecture for their drivers (called that 'Manger Transducer', as well as a damping technology called the 'Star Damper', as well as built-in Class-AB amps for both the (full range) driver and the twitter, are really impressive 'Speakers, which, admittedly, don't come cheap (retail price in the US is about $24,950), but then again, consider that the 'Big Boys' in the field, such as the Magico M3 ($75,000 sans an optional dedicated stand, at $9600, and (if for some unexplained reason) need to be augmented with subwoofers, they cost $22K each...The same goes for companies such as  YG Acoustics, Giya Audio, Revel, Focal, MBL, Wilson-Benesch, and the list goes on and on...So, taking into account the price of these, the Manger Audio 'Speakers are a great VFM proposition! And, the company manufactures a full line of other, less expensive, but equally impressive 'speakers. 

drbarney1,
You're not the first person to nominate Magnepan, but they are NOT a boutique company, and haven't been for many years! 

I’ll add my vote for Volti Audio. Fantastic speakers!
