I've tried that and retested it a few times (just to make sure I wasn't wrong), and the results here are much better by-passing a preamp and feeding the Pi directly into a power amp - no question!

Still dont' quite understand but I would install the Spotify app on your Mac in the mean time and just use that. You can get it from their web site.
Sorry, I can't explain it any clearer than I did in my last post. I'll have a look now at installing the Spotify app. When you say web site, do you mean the Apple website or the Spotify one? A link would be good!
