I can add my own experience. I picked up a Niagara 1200 to use with my TV and KEF LS50 Wireless II's. I used stock PC's for the KEF and 1200. I later moved I moved an extra Hurricane source cable from my main system over to the TV system. I put the Hurricane source between the wall and 1200. I feel like adding the Hurricane made as much of a difference to the system as adding the 1200 did.
