This graph shows that the STR-DN1050’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 103.8 watts and 1% distortion at 129.9 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 136.8 watts and 1% distortion at 167.0 watts.

There was no multichannel input to measure. THD+N from the CD input to the speaker output was less than 0.007% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –81.77 dB left to right and –79.25 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –107.58 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.04 dB at 20 Hz and –0.51 dB at 20 kHz. The center channel measures –0.05 dB at 20 Hz and –0.47 dB at 20 kHz, and the left surround channel measures –0.05 dB at 20 Hz and –0.52 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.01 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 106 Hz and the upper 6-dB down point at 112 Hz.—MJP

Although the STR-DN1050 passed our usual tests for 1080i and 1080p pass-through and offers HDMI 2.0 compliance for handling Ultra HD signals, it lacks the latest HDCP 2.2 DRM compliance that will likely be required for passing some content from future Ultra HD video sources to an Ultra HD display.

Hi guys. I were thinking of buying this receiver but I'm a bit worried about the HDMI2.0. Are you sure it has HDMI2.0? Sony says nothing about this on their homepage, Whathifi.com says it has HDMI 1.4. And what about HDCP2.2?

Before sending this review to press for our September print issue, we reached out to Sony and confirmed that all the HDMI inputs and outputs on the STR-DN1050 are HDMI version 2.0. You can find this in the specifications on their website; it's listed at the bottom of the specs list, right above the weight and measurements section. You can also confirm this by going into the user manual, which does not specifically cite the HDMI version (in any way that I could see) but which does indicate in a chart that the unit will process 4096 x 2160 video signals at 60 Hz, something only HDMI 2.0 can do. We're confirming HDCP 2.2 compliance now and will post as soon as we know.

Hey, Rob: Any word on HDCP 2.2 compliance? Thanks.

Thanks for the follow up reminder on this. Sorry to report, but Sony says the 1050 is NOT HDCP 2.2 compliant. So although it'll pass UHD signals at 60 frames per second, you cannot necessarily count on it being able to fully switch ALL encoded UHD content going forward. And now that we have firm word that a 4K Blu-ray standard is close to being finalized and hardware/software should be reaching the market by holiday season 2015, this may be a critical issue if you expect your AVR to do pass-through from your UHD sources to your UHD HDTV. Bottom line: we're discovering that we're currently in a no man's land where a lot of HDMI 2.0 products were produced with the older chips, apparently due to availability. New gen UHD displays from the major manufacturers, for example, mostly have the HDCP 2.2 compliance. Among AVRs, Onkyo is the only one that appears to be touting this feature in their 2014 model line up, although I don't want to say that no one else has it in any model. I do know that the $899 Marantz SR-5009 Mark just finished testing also does not have HDCP 2.2, and I've got a query in regarding the Atmos-enabled Denon AVR-X5200 we're evaluating.

We are now aggressively querying the manufacturers on this point for every AVR we review, despite their caginess on the matter; no one brings it up when it's not there. But the info will be up front and center in every test report from here and lack of compliance will be listed as a Minus bullet point until such time as this becomes a non-issue. By next year this won't be a problem; all the new units should have the new technology. But apparently it is a consideration today if you expect to use your AVR as the switcher between the emerging 4K streamers, servers, and disc players and a 4K display. We've edited some comments about this into the review, and taken the 1050's feature rating down by a full star to reflect the lack of HDCP 2.2 compliance. The Video Performance rating was kept at the same 4 stars; the unit performed well on video pass-through for regular HD signals, and I see this more as a feature content issue that may effect some buyers in the future, rather than a performance issue.

Hi Rob.
Thank you for your swift reply. I see now in the manual that it is like you said, 4096 x 2160 @60Hz, though it is limited to 4:2:0 not supporting 4:4:4 but I quess we cant have it all :) I will look forward to your results on the HDCP 2.2 compliance.

The big problem is anticipating what the next UHD blu ray standard will support/require. HDCP 2.2 will likely be part of that and the Sony receiver doesn't support that. If you want to jump on the 4K wagon, it's best to wait for next years AV receivers to catch up.

I am seriously considering picking up a Sony 1050 - Runners up are the Pioneer 1124 and possibly a lower-end Yamaha. Sound quality is a top concern, but given my low efficiency speakers (~87 dB), I am trying to keep power levels high. Recommendation?

Also, what is killing me is the idea that the Sony 1050 sounds better than the 1040, but the power/distortion measurements clearly favor the Sony 1040. I'm surprised this wasn't brought up or explained. The 1040 appears to produce at least 100 watts at well below 0.1%, and the 1050 seems to begin gaining a lot of distortion after reaching about 70-80 watts (almost at 10% distortion at 100 watts). Sure, that is less than a 3 dB different, perhaps, but the numbers are the numbers and this seems to be a power downgrade. Did Sony downgrade the transformer on this model or something?

To add to the confusion, the 1040 and 1050 have similar output in 5 channel drive mode. Was the wrong chart published in the 1040 article?

...but there are a lot of little things that were done to further tune up the sound of the 1050 vs. last year's 1040. Although more amplifier power comes into play when you're playing your system really loud (or trying to fill a very large room), there are other design considerations that will affect the sonic nuances that the trained ear can detect. For example, Sony told me and some other journalists during a press event that they even went as far as to swap out a particular capacitor in the signal chain many times until they found the one that sounded the best by ear during their listening tests. One of the things that's different is that this year's model benefited from extensive listening sessions in San Diego by the U.S.-based product manager and design team, and they were able to make a number of small changes that amounted to something overall.

Hey Rob,

I purchased this unit after comparing it to many different AVR units and found this to be the all around great value and provide the most features.

Now - time came to purchase speakers and any reputable speaker store tells me that these won't be powerful enough to run their speakers. With every person saying something different.

My question first is - will these function to power Triton Three by Golden Ear - and what would be the draw backs to this.

Second - can you please point me to the metric that best explains how to mate speakers to AVR units.

The Golden Ears state in their literature that they only require 20-400 watts per chanel to drive - with this set running at 8ohms - will that not be sufficient as technically it's meant to put out 165watt per channel?

Hey there,

nice review, thanks! So you wrote that you chose "Full Flat" as EQ. Could you explain why FF and not "no EQ" and where the actual difference is? Which setting would be closer to the "natural" soud of your speakers? I got the 1050 here and I have a really hard time to decide on an EQ...I'm mostly listening to rock and heavy.

Btw, I think the Sony is a bit on the "boomy" site at least regarding the bass but that could just be me.

I need to be able to use this receiver w/wireless (Sony) headphones that have their own transceiver. I need to be able to hear through the headphones while others listen through speakers. Can I hook the headphone transceiver up to the zone 2 audio out and get sound to the headphones w/o cutting off sound to the speakers?

I've been considering this receiver and called Sony to make sure some of the Zone 2 features are what Sony's marketing claims they are after reading many reports online. They confirmed that the marketing is not entirely accurate.

Though the second zone is independent, it cannot play any audio source, nor output them to the 2nd zone speakers as simply as Sony makes it seem. While the second zone does have an HDMI output that is dedicated, that will only play audio to the receiving source...meaning that if you are trying to plug a TV or projector into the second zone, the audio will only be available on the TV or projector, not any speakers you have connected to the second zone. If you want audio over the second zone speakers, you need to dual wire the receiver with analog/RCA cables from the source. This is part of the reason why Airplay won't play to the second zone, as well.

For me this was important for two reasons. I want to be able to output from my blu ray to a projector on the patio, using the patio speakers. I also want to be able to connect my computer (via HDMI) to projector or to play music. None of this would be possible without having to by adapters for both my blu ray and computer as they don't have analog outputs. This type of setup can be accomplished with any number of receivers and requires lots of extra effort (and cables)...it's not a feature.

I confirmed this with Sony customer support today.

Thanks for your post. I am looking for a receiver that has similar capabilities as you described, i.e. Truly independent zone 2 able to handle different digital input. Do you know any others in this price range? Onkyo maybe? Thank you

I have been a loyal yamaha receiver user for 30 years. They are work horses with conservative power ratings and excellent build quality. I own 5, including the first I ever bought. They all work perfectly.

But, being foolish, I was seduced by the low price of this Sony and the abundance of features.

By trade I was a sound engineer, recording artist and studio musician. The review as regards sound reproduction and features is accurate. I particularly like the remote and the mostly on screen menu.

Build quality is awful. This unit ran hot from day one. As in very, hot enough to burn your hand at medium sound levels. But it worked for about 6 months. Then it died. Now, I am very comfortable working on electronics so I took this unit apart to have a look see. It took about 2 seconds to diagnose the problem, failed transformer. It was actually discoloured. I removed it for testing and it is dead.

Sent the unit back to Sony and now the fun begins. Three months later, they haven't looked at it and when I offered to buy a transformer they can't supply it. Because, it doesn't have a part number.

I gave up 2 days ago and bought a nice yamaha, more money, lower rated power output and it barely gets warm.

Verdict: Sony makes cheap mass merchandise crap. Fine if you are from the generation that considers Bluetooth to be of good quality. Adequate for 100 dollar speakers. But so cheaply made, very evident inside, so sad. DO NOT BUY.

Good morning all. Hopefully you are still responding to this article. How would this receiver pair up with floor standing speakers? Does it have enough power to utilize the full potential of these speakers? For reference, I am interested in the Definitive Tech BP-80xxST series towers or the Paradigm Monitor series towers. I would mate the Definitive Tech's with just a center, no subwoofer, while the Paradigm's would get both a center and a subwoofer. I currently have Paradigm bookshelf 5.1 surround system. For simplicity reasons, I want to change my audio system to stereo.
