Bluetooth Music Receivers?

Not necessarily a preference for bluetooth but this seems to be the best option for me.

I currently stream iTunes Radio and Pandora from my iMac to my HT processor (Pioneer VX-32) via bluetooth.

I have two other 2CH set-ups at home (den and BR). One system uses a controller/amp the other an integrated amp.

I want to sometimes simultaneously play the same stream on two or all three systems at the same time.

If something other than bluetooth will work, I'm open to learn of it.

The limited bandwidth and 30' range are concerns. Other suggestions?

Nieuwen -- Thank for the suggestion. I considered AppleTV but yesterday one of the "techs" at the Apple store stated AppleTV would not work. I will pick a unit up and try it.

Since Apple TV outputs audio via optical connection, what type of device is needed to convert to analogue?

I know that a DAC is the device needed and I see devices starting at $10 and going up, way up. I guess I'm looking for a DAC recommendation at a "reasonable" price point.

Thanks for the info. I have heard of the Bereford TC-7510 and the newer TC-7520 as VG DACs. I look for them.

And thanks for the info regarding computeraudiophile.
