I just bought the Marartz7300ose last week and then I found out there were complaints (hometheaterforum.com) about a tweeter hiss at very low volumes with the analog cable hookup and with no music with the digital cable. I heard the hiss after receiving the receiver only with certain CD/DVD's. It went away in a few days and then my Kimber 4VS arrived and what a beautiful receiver. Cables do make a difference!!
