iPod, iPad, iPhone sound ?

Hi all,In one of my systems I run an i Pad through a Marantz 1060.This system was set up primarily for use with a tuner.I have added an old turntable and the i Pad.I listen to iTunes and Pandora with it . Question is would something like an HRT music streamer improve the sound ? Speakers are DCM time windows.Sound is ok but the tuner much better.I am not looking to change the amp.In a different system , my "digital " I use a Peach tree nova so I know the possibles of digital.I am just wondering if there is an inexpensive way to get a more analog sound ?
