McIntosh MDA200
I would NOT consider these brands boutique, just my opinion. Examples
Yamaha, Marantz, Technics, Rega, Cambridge, NAD, McIntosh, or anything made in China, etc....
All of these companies in and of themselves are very small, Yamaha, Marantz, Technics may be subsidiaries of much larger conglomerates but other than using them for R&D capitol they operate as private entities.
McIntosh has been using other small companies larger than itself to procure R&D capitol for decades and for the recent few it's been partnering with private equity companies for the same reason and don't be surprised that it's current affiliation with Bose ends sometime in the foreseeable future.
Rega and Cambridge audio are small privately held independent manufactures and NAD is a property of the Lenbrook Group of Pickering, Ontario, Canada who are active as part of the music supply chain in the Canadian electronics industry.
You should know your facts!
