I know I can do it with a tablet, or even a phone, but the sound quality is even too poor for my old ears. I could probably fire up an old computer, and use the sound card from that, but it seems in elegant.
Ideally, I want it controlled by tablet or phone, so I am thinknig of something like this:

WiFi Audio Music Receiver Adapter - AirPlay Compatible - Turns any existing Speakers Docks & Sound Systems into Wireless Streaming Systems - DLNA Stream Stereo Bluetooth Speaker 3.5mm AirMusic
There seems to be an abundance of units that will play via bluetooth from your phone. I am a little suspicious of those, Is that reasonable?
But I feel confident that if there is a group of people that can point me in the right direction, this is the place to ask

hope you can help.
