This receiver provided a very clean signal via the direct 5.1 analog audio inputs from both HD-DVD/Blu-ray disc sources, in addition to the Blu-ray/HD-DVD HDMI and Digital Optical/Coaxial audio connection options.
The RX-V3900 showed no signs of strain during very dynamic audio tracks and delivered a sustained output over long periods of time without eliciting listening fatigue.
In addition, another aspect of the RX-V3900 was its multi-zone flexibility. Running the receiver in the 5.1 channel mode for the main room and using the two spare channels (normally devoted to the surround back speakers), and using the provided second zone remote control, I was easily able to run two separate systems. I was able to access DVD/Blu-ray/HD-DVD in the main 5.1 channel setup and easily access XM or Internet Radio or CDs in the two channel setup in another room using the RX-V3900 as the main control for both sources. Also, I could run the same music source in both rooms simultaneously, one using the 5.1 channel configuration and second using the 2 channel configuration.
Using the Silicon Optix HQV Benchmark DVD, the scaler in the RX-V3900 does a better job htan many other receivers with built-in scalers. The Video Performance Test Results are on par with both the OPPO DV983H Upscaling DVD player and DVDO EDGE Video Scaler/Processor, which also use Anchor Bay Video Processing technology.
The RX-V3900 can pass a native 1080p source through to a 1080p television or monitor, or upscale any input resolution to 1080p. The image on a Westinghouse LVM-37w3 1080p monitor showed no visible difference, whether the signal came directly from one of the 1080p source players or was routed through the RX-V3900 before reaching the monitor.
What I Liked
1. Sound quality excellent in stereo and surround modes.
2. Analog to HDMI Video conversion and 1080p Video Upscaling via built-in ABT2010 Video Scaler/Processor.
3. iPod connectivity and control via either front USB port or accessory docking station.
4. Extensive speaker setup and adjustment options. The RX-V3900 offers both automatic and manual speaker setup as well as provisions for connection and setup of 2nd or 3rd Zone speaker systems.
5. Well designed front panel controls. If you have misplaced or lost either remote, you can still access the the main functions of the receiver using the front panel controls, hidden behind a flip-down door.
7. Second Remote Control provided that can be used with main system or for 2nd and 3rd Zone operation. The second remote is very convenient; very compact and only has most used functions; it is not cluttered with lesser-used functions.
What I Didn't Like
1. Heavy - Use caution when lifting or moving (more of a cautionary note than a negative).
2. Only one Subwoofer output. Although one Sub output is standard, it would be very convenient, especially in a receiver in this price class, to include a second Sub line output.
3. No front mounted HDMI or Component Video Inputs. Despite limited front panel space, it would be great to add component and/or HDMI connections to accommodate game systems and high-definition camcorders.
4. Speaker connections too close together. This is my pet-peeve with Yamaha Receivers. When using bare-wire end speaker cables, it is sometimes difficult to get the lead into the speaker terminals; another 1/32 or 1/16-inch distance between terminals would help.
5. Main remote not the easiest to use; very small buttons.
Added Note: The RX-V3900 is not for the bargain hunter and those who ignore user manuals.
The RX-V3900 delivers more-than-enough power for most rooms and provides exceptional sound with its high-current amplifier design. Practical features that worked well: 7.1 channel surround processing, analog-to-HDMI video conversion, video upscaling, and Multi-zone operation.
A high quality receiver should have the ability to perform well in both stereo and surround modes. The audio quality of the RX-V3900 in both stereo and surround modes was excellent, making it great for extensive music listening and home theater use. There was no sign of amplifier or listening fatigue.
I also found the analog to digital video conversion and upscaling functions to be excellent for a home theater receiver. Check out some video performance test results. Also, providing analog to HDMI conversion and upscaling simplifies connection of older components to today's HDMI-equipped HDTVs.
The RX-V3900 definitely has a lot of setup and connection options, making reading the user manual a must before using with your system.
The RX-V3900 packs in a lot of features and delivers great audio and video performance, but is pricey; definitely not for the bargain hunter. One the other hand, if you are looking for a high-end home theater receiver that can function as a complete centerpiece for your home theater system, consider the RX-V3900 as a possible choice. I give it a solid 4.5 Stars out of 5.
