The STR-DN1010's DCAC (Digital Cinema Auto Calibration) automatic speaker calibration system is super easy to use. Not only that, it takes about a minute to complete; just plug in the supplied microphone, bring up the Auto Cal page in the GUI, and initiate the program. Unlike Onkyo, Marantz or Denon's Audyssey calibration routines that require the user to repeat the procedure three or more times with different microphone positions, the STR-DN1010 gets the job done from a single mic position.
The DCAC determines each speaker's "size," frequency response, volume level, distance from the listening positions, and the speakers' optimal crossover frequency relative to the subwoofer. After we completed the DCAC we noted the DN1010 misidentified the size of the center speaker in our Aperion Intimus 4T Hybrid SD reference speaker system as "Large" (it should be "Small").
We didn't immediately make the correction in the STR DN1010's manual speaker setup menu; the sound balances were fine with the "Large" setting. The only potential problem with leaving the center speaker size as "Large" would be that an extremely dynamic movie soundtrack might overdrive or damage the center speaker (as a "Large" speaker, it would be sent full-range, deep bass signals).
In everyday use the "Large" setting wouldn't be a problem, and when we briefly experimented with changing the setting to "Small" we didn't like the sound as much. We used the speaker settings determined by the DCAC for the duration of our listening tests. Listening at commonsense volume levels we doubt STR-DN1010 owners would be taking undue risk with their speakers with the settings determined by the DCAC.
We did make one change in the Audio Settings menu: The STR-DN1010's factory default setting for D. Range Compression (dynamic range compression) is "Standard." With the D. Range Compression turned on our DVDs and Blu-rays dynamic range and impact were reduced, so we turned the D. Range Compression "Off." The default setting baffles us, especially since many owners will never realize the compression is turned on, unless they read the STR-DN1010's instruction manual or fully explore the manual setup menus.
We'd characterize the STR-DN10101's sound as warm and rich, and that was the case with all of the movies and music we played during our auditions. It was a big step up from what we've heard in our recent reviews of sound bar home theater systems. A receiver, used with a top quality speaker system like our Aperion Intimus 4T Hybrid SD produces a significantly bigger, more room-filling sound, with deeper, more powerful bass, and superior clarity than any sound bar on the market.
Listening to a recently released classical SACD, Benjamin Britten's "The Young Person's Guide to the Orchestra" in 5.1 surround confirmed all of the above observations. The sound was spacious, and the music floated free of the actual locations of the five Aperion speakers, so we could almost believe we were in a concert hall. This is an extremely dynamic recording, and the STR-DN1010 never showed signs of strain, even during the most demanding passages. Our sole criticism of the sound was the bass--there was lots of it, but definition was muddy. CDs were also too bassy, but other than that, they sounded great in stereo.
A coming-of-age rock bio-pic, "The Runaways," charts the history of the first all-girl punk band in the 1970s. Starring Kristen Stewart as Joan Jett and Dakota Fanning as Cherie, the girls struggle to get the band together. The sound of the girls playing in clubs and rehearsal studios was very good, in a "you-are-there" sort of way. The raunchy rock had plenty of punch and power. We next experimented with the STR-DN1010's D. Range Compression that reduced the soundtrack's soft-to-loud dynamics without overtly affecting sound quality. It does a good job.
To finish up we compared the STR-DN1010 with Pioneer's VSX-1020-K receiver. Before the advent of auto speaker calibration systems most similarly priced receivers sounded nearly the same, but the sound of these two, after calibration, was very large. First, on the Britten SACD the bass went deeper and definition was greatly improved with the Pioneer. In fact, the overall clarity of the SACD was dramatically better with the VSX-1020 receiver. Then again, some listeners may prefer the STR-DN1010's richer tonal balance, though you can sweeten the VSX-1020's sound with its various equalization and room-tuning adjustments and make it sound more like the Sony.
The violent gunfire and helicopter crash on the "Black Hawk Down" Blu-ray demonstrated the Pioneer receiver's home theater superiority. The differences in clarity and dialog intelligibility between the two receivers were easy to hear. The VSX-1020-K made the skinny Aperion 4T tower speakers sound like bigger, much more powerful speakers; with the STR-DN1010 we were more aware that the deep bass was coming from the subwoofer.
