I picked up the sr5000 and the sr4300 from another HT member. I really like the sound but neither have remotes. I am waiting for both the Marantz rc5000 and the rc2000 to come via Flea-Bay. I read that both have Marantz codes pre-programmed. The 4300 needs a remote to do set-up. I am hoping to keep one receiver/remote and sell the other. Can anyone verifiy if this is the case? I hate the fact you can't set-up the 4300 without the remote. Any suggestions? Anyone know the real differences between the two units?
