I got my 1120 yesterday!
My initial impression was that it was pretty wimpy. It's replacing my Onkyo 805, which is about 55 lbs compared to the 1120's 35 lbs. I knew this getting into it so it wasn't a surprise. No matter, I have two Crown 402D amps powering my front soundstage, so the Onkyo was only powering my four rear speakers, which was definitely overkill. In any event, after hooking everything in I started MCACC to calibrate my system. Oddly enough, after testing my speakers it said my front left and right speakers (PSB Goldi towers which are bi-wired) were reversed in polarity. I checked all the connections and everything was as it should be. The only thought I had was that maybe my RCA-to-XLR cables were the culprit since it splits one wire into three, but I frankly don't know. (Any ideas???) In any event, I ran the rest of MCACC and let it do its thing.
Not expecting any upgrade in audio, I bought this receiver for the Marvell chip. To get to the heart of the matter I tested a wide variety of video sources: DVD, Blu-ray, Netflix streaming, Youtube, OTA HD broadcasts and MLB.TV. I am not disappointed. The picture on my Pioneer 5080HD is frankly STUNNING, particularly with lower quality sources.
DVDs aren't magically transformed into Blu-rays, but I swear that if I were to tell any of my friends we were watching a Blu-ray and not a DVD they would all believe me. It's a pretty huge difference over what I had before. With DVDs it's not just the detail of the picture that's that much better, but contrast, black levels and colors (wow do they POP!) are all just so unbelievably perfect. After watching a Curb Your Enthusiasm Season 7 episode I questioned for the first time paying the BD premium. Again, DVDs aren't BDs, but the difference is now minor.
MLB.TV and Youtube benefitted even more, although one can easily tell which sources are lower quality. MLB.TV on PS3 is already a very good streaming source, but processed through the Marvell chip it's coming darned close to broadcast quality. I booted up a music video of "Bang Bang Bang" by Mark Ronson in 480p on Youtube and the quality fullscreen was very watchable, which I could not say before. Arrested Development on Netflix HD streaming was akin to watching a BD. That's not hyperbole, it was that good.
I only tested one Blu-ray, suspecting the difference to be minor. Those suspicions were largely reaffirmed because BD is already great, but the couple of scenes I saw in A History of Violence are as close to perfect as anything I've ever seen on a screen. That was a nice little plus.
In terms of audio, I only casually listened to a few MP3s and lossless WMAs. I don't have anything to note on stereo audio quality as I could not detect any differences between the 1120 and the Onkyo 805. Same with the DVDs I watched (LOTR: Two Towers, War of the Worlds) except that a few times when there was DEEP bass, either my sub or left front speaker popped. Not blew, but popped.This happened maybe three times while the sound was cranked. (Reversed polarity issue maybe?) I never had that issue with my 805 and the speakers were hooked up the same way to my Crown amps as before. (Any ideas there?)
In any event, as you can tell, I'm THRILLED with this receiver. The Marvell chip is all that and a bag of chips. I'll post more impressions in the next couple of days if I have any.
edit: the 35 lbs I cited was the shipping weight supplied by UPS in the tracking informaiton.
