Don't forget the stellar customer service for which Oppo is renowned. E-mail them a problem or question and they'll generally get back to you within hours. You think you're gonna get that from Denon or Yamaha? Heck, I once spent three weeks on and off trying to get a simple question answered by Pioneer!
Plus, their firmware updates are speedy and there's tons of info on what's going into them. Their manual is in plain English and very easy to understand. They pack an HDMI cable with their player. They give you the Spears & Munsil calibration Blu-ray plus the AIX Records calibration and music Blu-ray. Is there any other company that puts that much thought into the little things for its customers? So yeah, I'd say Oppo is the way to go. And remember, they have the 83 but also the 80, which is significantly less expensive.
