They are finally out! The new Onkyo 800 which is supposed to replace the excellent 797. I have a 2-week old 797 and it doesn't drop any codes or click through the speakers!. I guess I am one of the lucky ones. I can replace it with the new TX SR800 since I am still under 30 days. The difference in price is probably $100-$150. So which one to get? From my review of the specs the major differences are: - SR 800 has DD-EX and THX Surround EX while the 797 has only THX-EX. - SR 800 is a true 7.1 with 100X7 while the 797 is a 6.1 with a 100X6. You can go to 7.1 with an external amp. - SR 800 you can allocate the 2 back surrounds to a zone 2 to hear a different source in another room. You need an external amp to do that with the 797. - SR 800 has a pure audio mode but not the 797. - SR 800 doesn't have an on-off botton, only standby/off and doesn't have 12v trigger. Isn't the DD-EX same or very close to THX-EX? I have heard the 797 and it sounds great. Didn't get a chance to hear the 800. Any help is appreciated.
