Okay, I got to play with the new 911 last night. Here are some immeadiate observations:
1) This unit is a lot quicker then my last. At least twice as fast when doing a switch check. Also when I go to a new channel it is immeadiate with no lag time.
2) OTA tuner has definitly been fine tuned. I could never get my old 811 to find more than 7 digital stations, whether they were strong enough for a lock or not. Last night the new one tuned in 11 and locked in on 9!!! In fact, I was receiving a CBS station from over 70 miles away! Incredible. The new tuner definately locks on quicker. In fact very quick. A second at best and you have picture and sound. The old one could take up to 5 seconds or not produce any picture or sound at all. Sometimes even the old info button trick would not work. I do not have to do that with the new one--YEAH!!
3) Now when a signal is above 60 you get a lock with some loss and if the signal stays above 65 you get a lock with no loss! The old one would only do that at 70 and above. I have to get into the atic tommorow and readjust my power antenuator to see if I can improve the signal more.
4) The sound is better. At times when changing to a station that was supposed to be broadcasting in DD my Denon would default to a matrix setting. Pressing the DD button for the reciever would usually not change anything. Now when I change to a channel that is broadcasting in DD the Denon swithes to DD. I did this several times and the audio work the way it was supposed to. The audio also sounded more seperate and vibrant instead of slightly muted the way it used to.
5) While I do not believe that the Black level has changed for DVI I did notice that when I turned up the Black Level on my Pioneer 630HD that there seemed to be more dark definition. So perhaps there has been a change there too.
6) I haven't had a wait for upload when changing from an OTA digital channel to an E* channel. I also noted that if I try to watch an OTA digital channel whose signal is not strong enough for a lock that when I press the menu button the reciever goes to the menu. With the old 811 when you did this you would get the finding sat pique and then you would have to wait to change channels. How nice to not have to wait and be able to go to another channel.
These are initial observations. I received the first 811 in my area Dec 17th. It was changed out by E* before XMAS. I have waited until I was sure that there were new units before requesting a change out. Actually, the fact that my old 811 would not present any picture or audio when first tuned on caused my wife to ask if my new toy was broke. She refused to learn, as she calls it, "the secret button dance" in order to watch and would watch her set until I came home. This prompted the call for an exchange. So far I am very elated at the way the new 811 is working!
