I went to my local Tweeter here in South Jersey and picked up the 3805 today. I am replacing an older Denon 3802. I wanted to have a receiver that was a bit more up to date. My 3802 was becoming just a bit dated.
My first impression opening the box was not too good. At first I thought I got a unit that had been returned because it had masking tape holding the items in the box (see picture). After I looked some more I guessed that this was done because Denon did not have a new custom foam insert to hold the remote and other items. Kind of piss poor if you ask me but I went ahead and took it out of the box to begin setup.
Using a flashlight I looked inside through the vents to see whatever was visible. First thing that struck me was the power supply. It is the exact same power supply as in the older 3802. I could tell this because of the part numbers on the power supplies were the same! Aside from the common power supply everything else looked different.
The layout of the connections are good. A little more organized than the 3802 was. In my opinion anyway.
I'm using my 3805 to do component video switching. I feed a HD cable box and a DVD to the unit. When I was playing around with the new 3805 during setup I noticed some lines showing up on the TV whenever I select an unused video input. I was afraid that this 'noise' or whatever it is would end up making its way onto the video signals of anything the 3805 was controlling. So far I have not been able to see any interference when viewing a signal (cable HD or DVD), only seems to be visible when selecting an empty input. I'll look at this more over the weekend.
The setup menu is just about the same as the older 3802 with the exception of the additional items for EQ , etc. It is the same dull , boring display graphics. Nothing fancy. But it works.
My 3805 feeds Klipsch RF3 series speakers. Initial audio performance judgment is that it is slightly better than the 3802 was. Difficult to do an A / B type comparison between the two units obviously but having been used to the 3802 for a couple of years I was able to tell some difference. It sounds a little more brighter , perhaps I am noticing a bit more detail. The older 3802 only had single ended DACs on each channel. The 3805 has dual differential DACs on each channel. Possibly I'm noticing some more resolution in the audio. I will do more audio tests over the weekend !
I discovered that I could use my Radio Shack sound level meter as a calibration microphone ! See the pictures in the post following this one. I set my Radio Shack meter to the 80 scale, C weighting, and fast response mode. Connected an audio coax from it to the V. AUX L jack on the front panel of the 3805 and in the setup menu of the 3805 I selected V. AUX instead of MIC. During the auto EQ setup it takes the signal being fed into it from that input instead of the microphone jack !! And it worked. It successfully determined the speaker configuration/distance/ and EQ settings. (Well I guess one could say that the EQ settings are hard to tell if they are really correct or not but they sound pretty good once applied). So there you have it. I'll post more as I play more with it.
