Summary: Update 2: It took Yamaha Customer Service 6 weeks to email me an RMA number so I could return the defective tuner to them. They never explained why producing a number takes a month and a half. I shipped the unit back to them about two weeks ago and haven't heard anything about it. If nothing else Yamaha is proficient at chipping away at the two year warranty.
Summary: I have a large Mitsubishi TV and I really like the system with the 573 at the helm. Features are great. BUT, it has problems when going back and forth between HD and regular digital channels when running from cable-to-573-to-TV. The TV screen will often go blank or it won't receive the full HD signal unless I power off the 573 and repower it. Really aggravating for a system this advanced.
Summary: Bought the unit to replace a 10 year old yamaha that got fried by a power surge. For day to day use, watching directv and listening to cds, it is great! Also hooked up a Blue ray player and anytime I adjust volume of any blueray movie the picture goes out on my HD tv while volume adjusts. Only happens when watching movie on blueray player and thats it, VERY ANNOYING!!!
Pros: Good Remote Control, Great Sound Quality
Cons: Difficult To Set Up, Dont Hook Up A Blue Ray P
