This graph shows that the STR-DN1080’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 98.9 watts and 1% distortion at 121.4 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 161.0 watts and 1% distortion at 192.2 watts.

There was no multichannel input to measure. THD+N from the CD input to the speaker output was less than 0.015% 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 –92.74 dB left to right and –85.09 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –104.10 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.00 dB at 20 Hz and –0.46 dB at 20 kHz. The center channel measures –0.00 dB at 20 Hz and –0.49 dB at 20 kHz, and the left surround channel measures –0.00 dB at 20 Hz and –0.49 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.06 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 116 Hz and the upper 6-dB down point at 119 Hz.—MJP

I have question.. all sony STR DN-XXXX models takes 240 wattage from "wall" and all of them output over twice that..

Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 64.4 watts 1% distortion at 75.5 watts

Isnt 7 x 64w or 75w much over 240w ?

Could someone tell me how's this possible ? I mean Marantz 7011 takes 710w from wall and not even nearly output that same amount with same calculation

Have Sony invented solution for future coming energy crisis ? Could Sony sell me psu what takes 10w from wall and output is something like 1000w ? i could use it to keep my home warm...

I need to replace my old Yamaha AVR. In the price range I am looking at, it seems the Sony STR - DN1080 and the Denon X-2400H might be the best. I would love any input from Daniel Kumin or anyone else familiar with both. Thanks for any help.

I just bought my first 4k TV/Blu-Ray setup and sadly, my RX-V377 isn't HDCP 2.2.... After some research, I have found myself torn between the DN1080 and the X-2400H as well. Which did you choose?

Great receiver currently discounted everywhere. I replaced a Marantz SR5011 because Sony now supports DSD in 2.8MHz in 2.0 & 5.1 channels. Sorry folks, no 5.6MHz or 11.2MHz onboard DSD decoding. The STR-DN1080 downconverts to 176kHz/24 Bit. The workaround is hookup a Sony UBP-X1000ES (not the UBP-800X - same DSD decoding issues as the STR-DN1080N) and via Sony's proprietary encoding/decoding, you can play ALL DSD rates from the USB front port of both units. The onboard DAC (RCA left/right output jacks) are the only way to get true DSD playback without doing any messy PCM Downconversion. No DSD over PCM (DoP) support here either. It's Sony, so they don't need to sneak the packets onto PCM and then back into true DSD (I'm assuming).

One more thing (void goes the warranty). Open the chassis cover and you will see a ribon cable that leads from the top HDMI PCB down into the Main PCB BEFORE the ampifiers. With the aid of a STR-DN1050 schematic, I verified (ansd it's clearly labelled on the bottom header ANALOG GND, L+, L-, and the rest of the 6 main channels and the subwoofer channel. True differential outputs that bypass the internal volume control yet retain all D.C.A.C. EX functionality. A quality outboard preamp will allow you to use much better amplification than what built-in. Hi End AVR on a Low End budget.

Eh Sony...How's about an iOs App like the Marantz 2016 Remote App Huh ?
