Thanks for your suggestions.

I just need the ability to hear Pandora in any room in my house.
The only control I was looking for from TPS-6L, APAD was volume control.

Have you heard about autonomichome dot com. They have a product called Mirage Media Control system for Crestron which converts a stand PC into a media server. I have no idea what the cost would be but it looked interesting.

I will think about Logitech solution some more but right now I am hoping to avoid an additional system.

It is too bad that Crestron does not make an addon for Adagio AES/AAS that can do this.
