I've tried a few things for good portable sound around the house. One was the Outcast outdoor speaker - iPod goes in the remote controller:
And this is the speaker unit - sound is pretty good and if you want music on the back deck, it works well for parties, etc. and the sound is excellent - I'm sure you could set it up for streaming also:
I just have the iPod plugged directly into it there, so not using the control unit. Tried it in the shop but it got in the way, and frankly the sound from my computer speakers and sub-woofer is good enough for music through the day played off the desktop.
Now for the dedicated 2-channel system, a pair of these is working nicely:
But I know that when the transport goes on our Linn Unidisk player, getting it fixed won't likely be worth it, so that's why we are looking at streaming options right now. I will also get all the CD's I have ripped to high quality and use a music server...
