I returned my Marantz BD7004...
I loved the picture quality, but the noise from both the fan and the drive were distracting. I could hear it from 8 ft away. The fan sounded like a computer tower and the spinning of the drive was incessantly loud at times (like a computers CD/DVD disc drive), that it caused a whining resonance, vibration, through the chassis and into the wood shelf. Not sure if this was normal or the drive had mechanical issues. Either way, the fan noise was too audible for me. I was also disappointed with the mini-two prong AC input and the lightweight construction/materials. The design wasn't as nice in person either. I'd prefer a thicker aluminum faceplate to their plasticky aluminum/resin design. I guess I shouldn't expect too much for $800. Looks as though it doesn't get much better until you spend over $2K, which I don't want to do.
Time to try other BDP's. Somehow I knew it would turn out this way. You can't rely on opinions or reviews. You have to experience it for yourself. Plus this is my first BDP. I need to have some references to compare. Next up; PS3 or Oppo BDP-83.
