Brett Landes has so many businesses he can’t remember them all. He runs his own development and investment firms; is a partner of Vintage Interests, a real estate outfit; serves as primary shareholder of Lobo Tortilla Factory; and is a principal of Staubach Capital Partners, with $9 billion in acquisitions. Just to name a few.

But Landes, 46, doesn’t want to talk shop. He’d rather talk about the two 6-foot Wilson Audio Alexandria X-2 speakers, three FM Acoustic amplifiers handmade in Switzerland, and Faroudja high-definition projector in his new, over-the-top media room. “This stuff is my passion,” he says.

In this acoustically perfect space behind his renovated Fairmount Street offices, he can watch a movie on the 126-inch Stewart screen (Braveheart is his favorite) or kick back to some Clapton (he prefers Pilgrim), courtesy of five Wilson Audio WATCH Dog subwoofers. Though the renovation took a year and a half, Landes says the excitement was worth the wait. Besides, it gave him time to dream up more businesses he can soon forget he has.
