I have had a Sony 333es receiver for over a year now, but still consider myself a newbie. I have enjoyed browsing the forum and learned a lot in a short amount of time. One thing that caught my attention was the fact of setting speakers to either large or small. I looked at my receiver and I can't seem to find anywhere that allows me to make a change in this regard. Can someone explain to me what it means to set the speakers to large or small and also does my receiver have this capability?
