Thank you Al. I bet it was tricky finding those alternatives.
I ended up with a Grace Internet Stereo Amp (another name!). It only does a fraction of what I was looking for but it does stream Pandora. Additionally it specs only 16 watts per channel but it plays plenty loud in my small shop area. Also, I was able to connect a small sub via RCA cables. So it worked out well.
Thanks again for your help.
