Keith Moorman had to get Overture Audio out of its home across from the South Main Market, where he’s been selling top-of-the-line sound equipment since 1989, because the building is being razed to make room for a seven-story apartment house. He’s bought the former O’Leary paint store on West Stadium. “I was really fortunate to secure a place this well suited to my needs,” he emailed in August, and “…we’ll be starting the buildout/renovation this month. The showroom area will be noticeably larger.”
