As I thought, you are looking for what most of the mfgs will not disclose. Having worked in the industry for ~10 yrs( late 80s~90s) I can tell you qualitativly the following information: The market has gone through a lot of consolidation, especially in the last few years-Harmon Karden is the best example, but Klipsch has bought Aragon, and some others.... The industry can be divided into some managable groups that may help to get towards your answer. First are the Majors (mostly forgein)who dabble in High-end to maintain marquee, Sony, Philips, Marantz, Denon, Luxman and Harmon Kardon. The last is an interesting case as they have bought Madrigal, Mark Levinson, etc. As such, the majors are large firms where high end is but a part of their revenue. The second group might be the High-end majors, ARC, C-J, Krell. These companies have fluctuated between being very small to over 100 employees. most of these have been in the over 1 million in sales, but not on a consistant basis. Some runners-up in this catagory could be Cary, Martin Logan, Wilson, VAC and Theil. Most of the companies that make High-end equipment are small, 1~5 employees, w/ sales ~500K+/-. They are very sensitive to market conditions, and usually grow or shrink based upon reviews and show sucess.
I am constantly amazed at the number of companies that appear each year with new products. Most of these ar ebuilt in runs of 100 or so, and unless they sell quickly, that may be the last 100 made. This is one of the few industries that can be runn sucessfully out of a garage for years, some still are!
