D+M Group (formerly D&M Holdings), continues their program of divesting businesses it determines are “non-core” to the company’s central focus on the consumer-based Denon, Marantz and Boston Acoustics brands. This week, we learned that the company has cut a deal to license the professional products businesses done under both the Denon and the Marantz brand names to inMusic Brands, Inc.. This move closely follows the announcement last month that the company was selling off the Calrec Audio business to Electra Parters.
