I'm playing mostly flac, so I'm hoping to find a way so that I can't tell the difference. The bose sound dock was actually the one that sounded good, it's the headphone jack to receiver that sounds bad. I guess I'm just hoping to find a way to get a digital signal from; the ipod (running rockbox), a tablet, a zune, or any device that can do playback, by using USB. There doesn't seem to be any receivers that can do this.
One of my questions; do most USB DACs require drivers and basically only work with Windows or a linux OS that might have drivers? Or are they almost bypass devices that will take any digital audio sent to it and convert it to analog and ready for an amp?
If I am stuck with using 3.5 mm, does anyone see a problem with going from; digital (ipod), to analog (3.5 mm), back to digital (DAC, receiver, or dsp) and then back to analog and ready for an amp. It seems to be I would lose a lot through that process, but thats what I'm here for. If there won't be a noticable difference through that process, are there impedance issues when running a 10-12 ft 3.5 mm cable from the trunk to the dash?
I can't find much at all on the Alpine PXE-H660. Theres only one thread on page for of the link below on page 4, but it doesn't talk about the device at all. Does anyone have good things or bad things to say about it? I realize this is an integration peice, and that it won't help me with USB, but is it worth the $300 on a budget system?
