Re: Denon AVR-3808CI: An Overview
Probably not quite right, but 0 dB typically represents unity gain level for the amp's output on the receiver, so less than the amp's "full" power output is denoted with -x dB for the volume level, where x is the value of the amp's power output in terms of decibel level. So there may be positive x values (meaning you are over-driving the amp past its nominal output, and scratching toward its amp headroom limit), most of the time, the volume level will be expressed in terms of a negative decibel value.
In other words, the low-level audio signals (generated from audio channels from the HDM player) are attenuated by the volume level control from its nominal signal level. When you are at the max low-level volume level, that corresponds to a value of 0 dB, the unity gain level for the amp, that's just how it's expressed in audio engineering circles based on the logarithmic math that describes sound levels in terms of decibels.
No one in their right mind listens at the max amp level unless they are aiming for premature deafness. Any level of attenuation of the low-level audio signal is expressed as a value less than zero dB, so that's why the volume levels are typically negative dB values. So you might have volume levels that start from -72 dB and go up the way to 0 dB in increments of 2 dB as the volume level is increased, and it might also go higher, like +12 dB (depends on the amp design and its limits). An easy way to find out the highest volume dB value is to pause the DVD player, and just turn up the amp's volume control and see how high the volume value reaches, but you'll probably hear some hiss from the speakers as you max out the volume as the amp is being required to amplify anything from the signal, but some electronics may introduce the hiss at the noise floor, but some receivers have good silencing protocols to eliminate the hiss if you turn up the volume on a "blank" audio signal.

Sorry, remnants of a EE education from a few decades ago, tried to explain it in layman's terms as much as possible.

Re: Denon AVR-3808CI: An Overview
While I am officially starting to start saving for my Denon AVR-3808ci this month. I have a few questions for 3808 owners.
- How well is the 3808 decoding lossless format like Dolby True HD and DTS-HD Master Audio?
- Has there been any problems with the HDMI 1.3 switching?
- How good is the internal scaler? Are there any issues with the scaler?
- And have there been any issues with the Audyssey Setup?
My plan is to purchase the Denon AVR-3808ci to replace my Yamaha RX-V995 that currently sits in my main HT. I am also planning to upgrade my current Sony BDP-S300 Blu-ray player to the Denon DVD-2500 BT Blu-ray Transport. I want to make sure that the DVD-2500 BT will bitsteam Dolby True HD and DTS-HD MA to the 3808ci. I am going to be so jazzed later this year once I own both peices!



My goal for 2009 is to own both the Denon receiver and blu-ray transport.

Re: Denon AVR-3808CI: An Overview
Just ordered mine, excited about lossless audio and having one cable to the tv...not to mention not having to constantly switch tv inputs.
Means I'm going to have to re-watch all my BD movies.....shucks!

yamaha is very nice but love the warmth of the denon. it warms up the klipsch reference series for me. the yamaha 1800 is very nice too. looking between the 2 is tough desicion

I'm excited to get it; couldn't really pass up the deal at 6ave. I guess we'll see how it does, last 3800 series I bought I didn't much care for it...or the remote; however, I wasn't doing HD at the time and that was 2 years ago. My old 2801 is still my favorite receiver; my parents seem to like it

| The big differences between the 3808 and the 4308 are wireless networking, HD radio tuner and a second HDMI out. |
I was thinking that the 3808 had HD radio, but I guess I could live without it.

| A consideration for the Denon: it can be upgraded (for a fee) to support Audyssey Pro with Dynamic EQ. This gives it the the equivilent perfomance of the $2000 standalone Audyssey Pro processor. The Dynamic EQ is amazing. |
How much is the upgrade for the 3808ci ? Is it upgraded over the ethernet connection or off of a disc?
I am saving for the 3808ci but have I been considering stepping up to the 4308ci. The biggest reasons are the 3808 basically does what I need it to do and the extra cost of the 4308. And by not getting the 4308 I could take that money and put that down on a DVD-2500 BTci Blu-ray transport. 
The Pioneer Elite VSX-94 TXH has a ethernet port but I am not sure if it can be updated via the ethernet port or not. The Pioneer Elite VSX-92 TXH does not seem to have an ethernet port so I beleive that the 94 may be the only Pioneer Elite that has the ethernet. I seriously considered the Pioneer Elite VSX-94 TXH when I was shopping for my next receiver, but the Denon won.
