Its been hyped as the most powerful AVR in the world with 13.1 and extended 5 year warranty wow is that for when micro-processing chips fail just within few hours of use brand new out of the box or for bugs that Denon and Marntz engineers already know about but expect consumers to put up with it. Its got more bugs than Windows pc.\n\n\nEven my cat Magic seems uncertain about the Denon AVR-X8500H? \n\n\nAll is in brand new inside the box. \n\nDenon and Marnatz share their ideas or what ever it is? As the menus have more less same layouts with small differences.\n\nIt took least 2 hours to get the Denon fitted into place on the rack form undoing the leads on the Marnatz then placing the Denon on top of the rack and connecting the leads up one by one to make sure I don't miss-connect the leads.\n\n\nUndid all the leads on the Marnatz SR6012\n\n\n\n\nSort of side by side or view of both Marnatz, Denon as it feels like sticking another Onkyo back up on top of the rack. \n\n\nAlmost finished connecting up the leads to RCA pre-outputs and HDMI leads all in place. \n\nAfter a successful start up as these AVR's today really rely on software like computers only I think they are lot less sophisticated with far too many wrongs than goods with them and no not my opinion my personal, operating using it has lead me to believe this.\n\n\nDenon switched ON and goes into usual start up mode just like the Marnatz SR6012 does. \n\nSo when all looked like it was running well with DVD in the Panasonic UHD 4K player, playing, The Peacemaker (1997) and the sound sounding okay thou only presently set with x4 overhead surrounds even thou I was go to get the Height ceiling channels wired up later in the night, which is now and I'll delay it till Thursday, when the replacement Denon AVR-X8500H arrives and that I have the present one boxed up and handed over to the courier to be taken back to retailer and sent back to Denon so those eggheads can figure how or want went wrong with it, (during a firmware update that I was installing for that dts \/ imax enhance). \n\n\n\n\nI spent few times on the phone with my usual diplomatic approach - the swearing as I had to "keep clam" :D the dealer even gave me a direct phone number for Denon\/Marnatz and I hate computer voices on the phone and the list of options and just lost my cool and started swearing even thou it was non-human voice on recorded system I just HUNG UP! Called the dealer shop again and arranged to have another one brand new sent to me while the other is collected same day from the courier. \n\n\nGreen is the colour for EVIL. This must be a Demon or a Lemon?\n\n To be continued as the page run out of picture image space.
