If you've got a digital audio source, Samsung's DA-E750 can connect to it, either through its built-in dock (it supports some Samsung devices and 30-pin iOS connectors), or wirelesly, via just about any wireless standard, including Samsung's AllShare, Apple AirPlay, and Bluetooth. It's also great looking, and includes two vacuum tubes for that warm analog sound. Whether or not the tubes actually help, the DA-E750 does sound very good. But at over $600, it's one of the most expensive audio docks around, and tubes or not, it doesn't necessarily sound better than docks selling for less, like the $400 JBL OnBeat Xtreme -- though no other dock matches the DA-E750 for looks, versatility, and retro tech. Just be careful not to break those tubes.
