Pretty big price for the Denon D M41 music system (CD receiver plus speakers). I think this is one of the better mini stereo systems and it dropped in price from $500 to $350. Looks like Denon wants to move some inventory. I've been thinking of picking one up for a bedroom/office for a while.
It has a CD player, a tuner, headphone socket (with selectable gain),bluetooth (supports AAC but not apt x),sub out, RCA and digital inputs, and speakers. Not bad for $350.
It lacks networking other than bluetooth. It lacks apt x which makes the bluetooth feature less attractive. Still it's easy (and cheap) enough to add an amazon echo dot via rca or a google audio dongle via an optical input.
