Bose buys McIntosh

Bose is certainly innovative outside the small audiophile space. Their automotive system brand is well-placed in the mass market, which isn't a bad place to be. They have made a significant bid in the consumer home audio market against Sonos. Their personal audio and industrial audio (professional noise cancellation systems) are solid. Getting a brand that is welcome in the high-end vehicle market in places where Bose doesn't have the cachet makes sense.

As long a the New York McIntosh factory stays open they will be fine. The economy sucks and as big as Mac is they are still every small. 
 

honestly it might keep them around another 50 years or they could whore out the Mac name and devalue it totally…. Time will tell. 

It's inevitable that companies like McIntosh that produce equipment that lasts decades isn't a profitable business model.  It wouldn't surprise me if for every 10 McIntosh sales transactions 8-9 don't represent any revenue to McIntosh as they're likely sales of pre-owned McIntosh equipment between private parties.
