This move is nothing more than Circuit City terminating its decades long relationship with Harman International and picking up D&M Holdings' brands instead.

Harman provided CC with h/k, Infinity, and at one time JBL components. D&M Holdings owns Denon, Marantz, McIntosh, and Boston Acoustics. For now, the only D&M brands making their way into CC stores are Denon and Boston.

D&M Holdings also has a presence with Best Buy through its Magnolia division, and recently started moving Denon products into the Best Buy stores. With so much crossover between CC and BB/Magnolia, it would not surprise me if Harman winds up getting into BB's Magnolia stores. Aside from h/k and Infinity, Harman also owns Lexicon, Mark Levinson, and Revel, brands that are very much within Magnolia's target niche.

A couple of months ago, I noted that a lot of brands seem to be consolidating their distribution into these all-in-one conglomerates, and the major chains are picking up brands as a group. For example, Sumiko is the North American distributor for Sonus Faber, Vienna Acoustics, Pro-ject, and Primare. Magnolia (including its locations inside of Best Buy) stocks all of those brands, and they occupy a considerable amount of space inside Magnolia's stores.

Klipsch recently purchased API, which owns Energy, Mirage, and Athena. It would not surprise me to see them further diversify by picking up an amplifier/processor manufacturer. BB carries Klipsch and Athena already, so it would not be a stretch for the other brands to move into BB/Magnolia stores.

Paradigm's also a conglomerate of sorts because they also own an electronics division (Anthem and Sonic Frontiers) and an AV furniture division (Premier). While they don't distribute to large chain stores in the U.S., most of the dealers that carry Paradigm's speakers also carry Anthem amps and Premier stands.

Same thing with B&W, which has a distribution relationship with Rotel. That would explain why most B&W dealers carry Rotel amps.
