This is a review and measurements of the YAMAHA R-N1000A Network Receiver. Its list price is 198,000 JPY in Japan and $1,999.95 in the U.S. The retail price should be lower than that, as it is on Amazon US. (EDIT: As of November 10, 2025, Amazon.com is selling this at its list price.) I bought it at a retail store in Tokyo.
The following were used for the measurements:
The R-N1000A is a network receiver, so users will typically use its internal DAC. Therefore, I first measured the performance of the internal DAC using the pre-out. Measurements were taken with the amplifier volume set to -14dB and a 2Vrms output in the Pure Direct mode (which skips the tone controls, balance, loudness, etc.).
Increasing the volume raises the pre-out voltage, but clipping occurs above 4Vrms. The R-N1000A allows you to set the “Max Volume,” so it's best to set it within a range that avoids clipping.
1.1 DAC Pre-out SINAD/THD+N
1 kHz sine wave, Amplifier volume -14 dB, 2Vrms pre-out.
Left channel: SINAD = 98.0 dB, THD+N = 0.0013%
Right channel: SINAD = 98.4 dB, THD+N = 0.0012%
These are very good for an amplifier-integrated DAC.
I also connected the Allo Boss2 streamer to an analog input (LINE1) and measured the pre-out.
Allo Boss2 RCA out > R-N1000A LINE1 input > Pre-out
Inputting a 2Vrms signal from Boss2 to LINE1, the pre-out at volume -14dB was 2Vrms, the same voltage as when using the internal DAC. SINAD was also good with the analog input.
Left channel: SINAD = 99.2dB, THD+N = 0.0011%
Right channel: SINAD = 100.3dB, THD+N = 0.0010%
If you need an external audio player or streamer, you can connect it to the R-N1000A with confidence.
1.2 DAC Pre-out Measured Level (Vrms) vs THD+N
Measured Level vs THD+N is stable. The SINAD at 2 V was 97.6 dB. The best SINAD is 100 dB between 1 V and 1.8 V.
1.3 DAC Pre-out Intermodulation Distortion (IMD)
IMD SMPTE (60 Hz & 7 kHz 4:1) (dB) vs Generator Level (dBFS), Left channel only. The measurement results for the right channel were nearly identical to those for the left channel. (It seems that REW's Overlay Window does not support this graph.) To prevent digital clipping, the maximum Generator Level has been set to -1.7dB (so, the measurement has stopped at -1.7 dB.).
There may be a sign of “ESS IMD Hump”.
1.4 DAC Pre-out Dynamic Range
To measure the dynamic range, a -60dB signal was output from the DAC Pre-out and amplified by +60dB using the Cosmos APU.
Left channel: SINAD @-60dB = 45.9dB, Dynamic range = 45.9dB + 60dB = 105.9dB
Right channel: SINAD @-60dB = 45.8dB, Dynamic range = 45.8dB + 60dB = 105.8dB
1.5 DAC Pre-out Linearity
Relative output level (dBFS) vs ADC input level (dBFS), again, Left channel only. The measurement results for the right channel were nearly identical to those for the left channel.
Generator Level 0dBFS = ADC input -3.07dBFS. Therefore, the portion at -3.07dB on this graph is linear. Below -110dB, linearity is lost due to noise, but from 0dBFS down to that point, it is linear.
1.6 DAC Pre-out Jitter
J-Test signal FFT, looks okay.
1.7 DAC Pre-out Roll-off Filter
White Noise FFT, Left channel. The roll-off filter is slow. I prefer faster ones.
Though this explanation is a bit complicated, ...
REW's Generator displays a “Signal is clipping at digital full scale” warning when the white noise output level exceeds -9 dBFS. It is likely that REW’s white noise requires 9 dBFS of headroom. If the REW's dBr (Y-axis for relative input to output dBFS levels) is set to align the maximum input level at 0 dB, the average level of white noise would be -9 dBr (as this graph).
Therefore, roll-off at 22 kHz = -16.8dB on this graph - white noise level (-9dB) = -7.8dB
1.8 DAC Pre-out Frequency Response
The DAC pre-out frequency response is essentially flat at 192 kHz sampling rates. However, the pre-out levels drop before 20 kHz at 44.1 kHz sampling.
44.1 kHz Sampling: 2 V @1 kHz, 545 mV @20 kHz (-11.3 dB drops)
1.9 DAC Pre-out Multitone
Effective Number of Bits (ENOB) = 17.5bits, TD+N = -90.9dB.
1.10 DAC Pre-out THD+N vs Frequency
THD+N is stable within the audible range with 192kHz sampling. However, with 44.1kHz sampling, THD+N increases rapidly above 10kHz. This is primarily due to ultrasonic noise rather than harmonics, likely caused by the slow roll-off filter. If the ultrasonic band is not measured (by REW’s Distortion settings “Use distortion low pass”), this increase in THD+N was not observed (blue line)
2. YAMAHA R-N1000A Amplifier Measurement
Again, the internal DAC was used for the amplifier measurements as R-N1000A users will typically use it. Measured in Pure Direct mode.
2.1 Amplifier SINAD/THD+N
Measurements were taken with the amplifier volume set to -36dB and a 4.45Vrms output into 4 ohm (about 5W). Leakage from the main power supply (50Hz) and its harmonics are observed, but the SINAD/ THD+N is sufficient for an AB-class amplifier.
Left channel; SINAD = 89.1dB, THD+N = 0.0035%
Right channel: SINAD = 89.6dB, THD+N = 0.0033%
2.2 Amplifier THD+N vs Power and Maximum Power
You can get 4.45 Vrms output either by setting “Generator Level 0 dBFS and Amplifier Volume -36 dB“ or “Generator Level -36 dBFS and Amplifier Volume 0 dB“. However, the SINAD/THD+N differs by each setting. As this graph shows, setting the amplifier volume to 0dB results in a 10dB increase in THD+N (mainly N rather than THD) compared to setting it to -15dB.
Distortion increases on the right channel before clipping.
The maximum power into 4 ohms before THD+N saturation is 153W.
Left channel: -92.1 dB (0.0025%) THD+N 153 W + 153 W into 4 ohms.
Right channel: -82.9 dB (0.0072%) THD+N 153 W + 153 W into 4 ohms.
The maximum power into 8 ohms before THD+N saturation is 97W. Again, distortion increases on the right channel before clipping, but still better than the nominal spec.
YAMAHA’s nominal specification is [20 Hz-20 kHz 0.07 % THD] 100 W+100 W into 8 ohms.
Actual performance is better than the nominal spec.
Left channel: -91.7 dB (0.0026%) THD+N 100 W+100 W into 8 ohms.
Right channel: -84.8 dB (0.0058%) THD+N 100 W+100 W into 8 ohms.
THD+N vs Power is measured at each frequency (20 Hz, 200 Hz, 500 Hz, 1 kHz, 5 kHz, 10 kHz, 15 kHz). Rise in distortion with frequency. Power loss at 20Hz.
EDIT: This measurement used an external DAC (TOPPING D30Pro). All other measurements used the internal DAC.
2.3 Amplifier Crosstalk
Since REW does not have a crosstalk measurement mode, I sent the signal (4.4Vrms sine wave) to the left channel and verified crosstalk by measuring the difference between the right and left channels.
1kHz L: -19.7 dBFS – R: -105.5 dBFS = Crosstalk 85.8 dB
10kHz L: -19.8 dBFS – R: -88.2 dBFS = Crosstalk 68.4 dB
2.4 Amplifier Frequency Response
Amplifier Frequency Response is essentially flat.
2.5 Amplifier Multitone
Effective Number of Bits (ENOB) = 17.2bits, TD+N = -82.4dB.
3. YPAO Automatic Room Correction
YAMAHA R-N1000A has an automatic room correction “Yamaha Parametric Room Acoustic Optimizer” or YPAO. The graph below shows an example of placing the Revel M105 in a room and performing room correction using YPAO (vs Pure Direct mode). The graph applies REW’s psychoacoustic smoothing.
The left speaker is placed in the corner of the room (0.35m from the left wall, 0.5m from the back wall), resulting in a boost in bass around 70 Hz. YPAO effectively suppresses this boost. The measurement microphone was placed at nearly equal distances from both speakers, but YPAO measured 1.75m (5.7ft) to the left speaker and 1.80m (5.9ft) to the right speaker, automatically raising the right channel's level by 2dB. A +2dB correction for a 0.05m distance difference seems excessive, but it can be manually adjusted. Rather, I'm concerned about the boost in the sub-bass range on the right channel.
I also tried YPAO with a different speaker Ascilab F6B in the same room. Again, the boost in bass around 70 Hz was well suppressed, but YPAO boosted in the sub-bass range.
Unlike other automatic room corrections (such as REW’s “Match response to target”, WiiM’s RoomFit and Dirac Live), YPAO is 100% automatic. You cannot set the target curve, frequency range to be corrected, max boost, max Q, etc. While YPAO cannot perform perfect room correction exactly as you specify, it can automatically perform corrections like the example above without requiring knowledge of room gain or room correction (PEQ/IIR, FIR, etc.).
4. Network features
R-N1000A supports AirPlay2, Spotify, Amazon Music, Deezer, TIDAL, Qobuz, pandora and SiriusXM. But some features are limited.
5. Conclusion
The performance of the R-N1000A's preamp and main amplifier is very good. The internal DAC is also very good except for the slow filter. Although the YPAO feature is easy to use, it is functionally limited. The network features are good, but some features are limited.
I'm satisfied with the R-N1000A as our family's shared receiver in the living room. Everyone enjoys FM radio, HDMI ARC, and Spotify Connect. For the average person, an all-in-one solution offers superior usability.
However, when I'm alone, I use the R-N1000A purely as an integrated amplifier, playing music via MPD or Roon on the Allo Boss2 Player.
I do not recommend the R-N1000A to the audience of ASR. The amplifier section of the R-N1000A is based on the A-S801 Integrated Amplifier. Given the price difference between the R-N1000A and the A-S801, it makes more sense to buy the A-S801 and a streamer, such as the WiiM Ultra or the Bluesound Node N132.
The following were used for the measurements:
- REW Pro
- E1DA Cosmos ADC (non-iso version, Grade B.)
- E1DA Cosmos Scaler (as a 0dB input buffer, not as a scaler.)
- E1DA Cosmos APU (as a +60dB preamp.)
- miniDSP UMIK-1
The R-N1000A is a network receiver, so users will typically use its internal DAC. Therefore, I first measured the performance of the internal DAC using the pre-out. Measurements were taken with the amplifier volume set to -14dB and a 2Vrms output in the Pure Direct mode (which skips the tone controls, balance, loudness, etc.).

These are very good for an amplifier-integrated DAC.
48kHz Sampling, FFT length 32k, 16 Average
I also connected the Allo Boss2 streamer to an analog input (LINE1) and measured the pre-out.
Allo Boss2 RCA out > R-N1000A LINE1 input > Pre-out
Inputting a 2Vrms signal from Boss2 to LINE1, the pre-out at volume -14dB was 2Vrms, the same voltage as when using the internal DAC. SINAD was also good with the analog input.
Left channel: SINAD = 99.2dB, THD+N = 0.0011%
Right channel: SINAD = 100.3dB, THD+N = 0.0010%

1.5 DAC Pre-out Linearity
Relative output level (dBFS) vs ADC input level (dBFS), again, Left channel only. The measurement results for the right channel were nearly identical to those for the left channel.
Generator Level 0dBFS = ADC input -3.07dBFS. Therefore, the portion at -3.07dB on this graph is linear. Below -110dB, linearity is lost due to noise, but from 0dBFS down to that point, it is linear.
1.6 DAC Pre-out Jitter
J-Test signal FFT, looks okay.
48kHz Sampling, FFT length 128k, 16 Average

1kHz L: -19.7 dBFS – R: -105.5 dBFS = Crosstalk 85.8 dB

4. Network features
R-N1000A supports AirPlay2, Spotify, Amazon Music, Deezer, TIDAL, Qobuz, pandora and SiriusXM. But some features are limited.
- Roon Tested (via AirPlay2), but not Roon Ready (RAAT).
Spotify Connect is supported, but Spotify Lossless is not supported. (EDIT: R-N1000A's firmware Ver.1.12 supports Spotify Lossless. Thanks for letting me know, @xbogey22)- Qobuz is supported via the YAMAHA MusicCast app, but Qobuz Connect is not supported.
