Thanks again. In fact, I am not really into the "home theatre" thing. It is nice to have the function though. My perferenc is to start with 2 good speakers and not bad receiver which not so sure stereo or AV, cause some fans said stereo receiver with AC-3 function would also be nice just for living room.
BTW, have you heard of (ONKYO ed-901B) Dolby AC-3 surround decoder?
