With my slimdevices Transporter and squeezebox there is a consensus that wireless is better than the hard-wire connections i have been using.
Hmmm, I've heard the opposite, at least with the Transporter. I've read that ethernet is the superior connection with the Transporter. I have not done any experimenting myself though, so cannot confirm or opine either way. I use a Modwright Transporter.
Regarding the question; I thought it was difficult to pull audio files off of an iPod...or did they finally change that stupid feature? Why is it "MUCH" easier to share via wireless? I'm not sure what you mean by that.
As was said, the spot whre the conversion to analog seems the real key... not so much the way the info gets there.
I wonder first off, whether errors in transferring files can occur, much like an error read off a spinning disc might occur?
I don't know if I agree that the conversion to analog is everything. There are so many things, which I guess are a part of that in some way shape or form. Jitter reduction would certainly be top of the list in improving sound. Are zeros and ones just zeros and ones? Check out Peter's input
and the responses on this thread, which is about a different subject, but goes to illustrate there's more to it...perhaps. Short answer - I don't think it's likely to affect the quality to transfer files.
