You wouldn't connect a tv or record player to either of these devices. They can work one of a few different ways:
- connect them to your existing stereo system (amp, speakers) as you would a cd player or other device. Your phono and tv could be connected to this too.
- connect a pair of powered speakers (ones with built in amp and volume control like pc speakers have) to the either the sonos or squeezbox. In this scenario it would be a stand alone system, with no integration with other components.
- or, if i'm not mistaken, i think sonos has some sort of all in one box that includes the sonos reciever as well as built in speakers - but I could be wrong about this. I'm not familiar with their product line though. For all I know they may have a receiver with built in amps that can power speakers of your choosing.
You would definitely NOT connect a phono or tv to either of these devices.
I'd suggest visiting a local sonos dealer and find a salesman that knows wtf he's talking about regarding the sonos product line.
