A lot of companies (eg. Denon) do the same thing. ALl the midrange products are packaged up two different ways -- one line aimed at the "high end audio stores" and another line aimed at the big box stores. That way everyone thinks they have an exclusive line.

A nicer way of putting it would be that the really high end stuff only goes to the audio stores, the real low end stuff only goes to the big box stores, but for the midrange stuff which both stores want it's easier (and arguably a better use of money) to share the design between both lines. Typically the styling is different and there are a couple of other differences but the electronic guts are the same.

Same idea as GM's different brands which share 90% of the underlying platform...

For Denon, each of the models like "2803" has a corresponding "9xx" model sold in the big box stores.
