Well I've decided to keep the 5803 and I also aquired a Yamaha M-65 power amp (FREE!!). I have sold the front speakers and I am in the process of replacing. I got a great deal on a Meadowlark Audio center through their direct liquidation. Its a 4ohm speaker. I am also considering a pair KEF Reference Model Ones ($500!)...also a 4ohm load. I know the Yammie would have no trouble with the KEFs...my concern is the Meadowlark center (not yet arrived). Will the 5803 be OK with the center? I am thinking it should, especially since the front channel load being handled by the yammie.
I did a forum search, but didn't come up with anything. Sorry if this has been answered before.
