The R-972 is Sherwood Newcastle's flagship receiver and boasts seven channels of amplification at 100 Watts each. It's also pretty hefty, weighing 46 pounds and measuring seven and five eighth inches high by 17 and three-eighths inches wide by 18 inches deep. The feature set and connection options are plentiful and highlights include: four HDMI 1.3 inputs, a full complement of analog and digital audio connections, a Silicon Optix Reon video processor, lossless audio - DTS-HD Master Audio and Dolby TrueHD, 3-Zone operation, and arguably the most advanced room correction system currently available - the Trinnov Optimizer. There's also a front panel USB input, useful for playing music from a hard drive, updating the receiver's firmware, etc. The remote is universal with full learning functionality and RF capability (antenna included). It doesn't end there as the R-972 is loaded with other cool features I'll get to later.
I'm really picky about packaging and in this regard, Sherwood didn't disappoint as both the unit and accessories were solidly and intuitively packed. The manual is detailed and fairly straightforward, although there's nothing in there describing the Silicon Optix Reon video processor, which I found odd as it's a notable feature. As a matter of fact, I wouldn't even have known about this feature were it not for the Reviewer's Guide they sent. Anyway, I connected the unit to my Panasonic Blu-ray player and Verizon FIOS DVR via HDMI cables and connected my Squeezebox with an optical cable. For those unconcerned with room correction and other tweaks, the Sherwood sounds great right out of the box. Ok, that concludes my review, thanks for reading. Actually, even newbies can be up and running with this receiver in 15 minutes. The engineers went to great lengths to make it easy to use and pulled it off. But the goal here is to find out if this beefy beast is worth your 1,800 bones, correct? So let the tweaking commence.
I connected the included setup mic, which set atop my tripod looks like something out of The Empire Strikes Back, and started with room correction - Trinnov style. It must be noted that the R-972's setup menu is one of the cleanest and most user-friendly I've seen to date. Navigation is simple and straightforward, and the menu design is highly sophisticated. Unlike most room correction systems, which only measure the distance from the speaker to your listening position and cannot compensate for poor speaker positioning, the Trinnov Optimizer measures the location and response of each speaker three dimensionally, using a wild looking setup mic with four microphones. Once the measurements have been taken and the mathematical calculations applied, the Trinnov Optimizer allows the listener to get as close as possible to hearing the sound as it was heard in the studio during sound mixing. All this looks good on paper, but is it hyperbole? The whole process only took about 15 minutes, so I just sat back and let the Sherwood do its thing while trying to keep my wife out of the room - these tests require silence. Once the calculations are done and saved, you're able to make tweaks to the system, such as listening position (up to three can be stored), Room EQ which adjusts the frequency response, Trinnov Spatial Mode which makes spatial corrections based on speaker positioning and distance and finally Trinnov Remapping, which gives you two soundfield choices - Music or Cinema. I think that its important to point out that every home theater will produce different results, so simple trial and error should be your best bet when working with different room EQ modes.
While I typically begin any receiver test with two-channel music, I couldn't help myself and went straight for The Dark Knight on Blu-ray (Warner Home Video) in Dolby TrueHD. The sound was immersive, cage-rattling actually. The opening scene of the bank robbery produced several 'jump from my chair" moments and I knew that, at least with regard to movies, the R-972 was a solid rig. I did some A/B testing, watching the now famous car chase scene with the Trinnov system engaged and then with it completely shut off. I've never been a big fan of room correction systems, and I've tried several. My experience has been that manual adjustments (using a sound level meter and tape measure) will typically provide the most sonically pleasing result. In the case of the Trinnov Optimizer, color me converted. As Sherwood states in their Reviewer's Guide, the system truly is a "game-changer." The best word to describe the difference in watching a film with the system engaged is immersion. With typical room correction, it's easy to identify from which speaker the sound is emanating; whereas with the Trinnov system you're placed in the middle of a sound field, which is truly ideal for movies as well as music. The sound envelopes you, and rather than moving from speaker to speaker, it moves through the space in your room as a whole. This is a bit difficult to articulate in writing, so I highly recommend finding a Sherwood Newcastle dealer and listening to a demo of the Trinnov Optimizer in action. Sherwood had a demonstration going at this year's CES (coincidentally featuring The Dark Knight), although it was on a noisy showroom floor and difficult to fully appreciate. Speaking of CES, it's worth noting that the R-972 won their Innocations Design and Engineering Award.
