How to stream audio to multiple speakers from Mac, iOS, Android

If you want to stream audio output to multiple speakers from your Mac, PC, iOS or Android device, I can tell you that this DIY article is spot on. Based on that article I just did a very similar thing, with good results. The only caveat is that the volume knob on the Lepai LP-2020A+ is very tight, and only seems to work in certain positions, but other than that, the approach works as advertised. I went with the Micca MB42 Bookshelf Speakers for $59, but in retrospect I wish I had tried the smaller Micca COVO-S Compact 2-Way Bookshelf Speakers.
