we have different preferences.. i prefer an amp for mine because i want a little more bass impact and depth.. my ipod is sufficient for me.. but I know what you're talkin about.. the DAC on my macbook (neutral) is miles ahead than the ipod.. it unleashes the full potential of the w4 IMO.. the closest thing I heard comparable to my macbook is the NU Force icon Mobile.. try the new NU's iDo .. but they are designed for Apple only i guess..
hope this helps
