The Bel Canto C5i is an integrated dac amp. 60W RMS into 8 ohms, 120 into 4. MM Phono input, Line input, line (pre amp) out, headphone amp, coax x2 toslink x2 and USB. It runs cool, is even handed at all volumes and the fact that its designer started Bel Canto making SE Tube amps, means the sound is smoooth...
I use mine with an Apple TV for eg, digital out from apple TV to Bel Canto. Then control what you Airplay (stream over the air from your iPod) on apple TV with the I pod touch or iPhone as a nice graphic interface remote incl album covers, track titles etc.
All I am saying is docking an ipod puts the beautiful user interface far away from you, a waste. An Apple TV or Airport Express, digitally connected to DAC sounds cool and is lots of fun. You could also just connect the computer with USB to a Bel Canto c5i for eg and then use the idevice to control what the computer plays.
Laptop>Bel Canto> Speakers, great system. Add iDevice for cool control.
What I am saying is consider Apple TV or Airport Express with a DAC or digital input capable amp for eg.
