MARANTZ NA7004 or LOGITECH SQUEEZEBOX TOUCH WITH AUDIOLAB M-DAC?

Hi everyone! Yes, the title says it all - I'm getting an Audiolab M-Dac for my Hifi and I'm going to be playing Flac, Wav and 96khz/24bit files through it. Q1. Would there be any difference whatsoever if I was streaming these files through a Marantz NA-7004 or a Logitech Squeezebox Touch? I wouldn't be using the Dac in the Marantz or many of its other features, so effectively it will just be used for streaming music. Q2. Would I be wasting my money paying for the higher priced Marantz? Q3. Are there any components / circuitry that would affect the quality of the streaming. Q4. Does the Marantz have superior jitter levels than the SBT? Q5. Does a streamer make ANY difference to the quality of music if the files are being output to a Dac? Are the files just being sent out as 1's and 0's? Thanks for all your answers in advance. If you only have an answer for one of my questions, I'd still like to hear it!
