I wasn't all that happy with the 3805, in biamping mode I couldn't get rid of some hum, no matter what I tried.
Cinema sound was fine, but music (especially stereo) was a bit weak in the knees for the mids, and slightly strident in the treble.
So I sold it for my current SR9600 Marantz, sounding much more musical and warm (even slightly too warm when coupled to the DV9600 player) and also more "engulfing" when it came to movie sound.
It also taught me not to value video switching too much, since the D. and the M. both showed a slightly veiled pic with different saturation when fed with hdmi.
I reckon, when you can afford a 990/1770 you can also afford a good scaler, this always give you more tweaks than any receiver.
I'm very happy with my DVDO HD+, it made possible to use 576p (PAL) on my rather NTSC-leaning Panny plasma DVI input board.
Now the M. has to go too because it still lacked the awesome power my previous Rotel RMB1095 final amp exhibited.
I noted over the years that massive power does a lot for the sound quality, especially the low bass, and for dynamics too: even the M. can sometimes sound slightly compressed when playing a SACD or DVD-Audio (fortunately the SACD isn't as defunct in Europe yet as it is in the USA, we even saw many new classical cds my fringe companies).
Many people declared me nuts buying the 1077 for my 4 x 4 m listening space, but I stick to what my old ears told me!
Pfew, here you saw what long texts a real hifi nerd can write when he's at it!
