Relationship between McCormack and CJ?

I noticed that McCormack Audio and Conrad Johnson have the same mailing address in Fairfax, Virginia. Presumably McCormack was bought by CJ - what's the relationship, business-wise and technically between the two companies and their products? Are they now designed by what is effectively the same team?

I guess I'm now curious about other consolidations in the industry. I know that Madrigal and HK control fairly large ranges - who else? Is CJ bigger than first perceived too?
