Actually, that's just for black. For the privilege of having the silver version you must pay another 100K Yen.

Kind of reminds me of the movie Crocodile Dundee, where someone tries to rob him on the street and he pulls out this huge bush knife, saying, "This is a knife!“

So, folks: "This is an amplifier!!!“

It is good as an amplifier, but not better than an AVR-X3700H as an amplifier based on the test result such as SINAD, FR, probably except for cross talk.

I wish NAD would re-release a modern version of the NAD Monitor series 7600 receiver. Or 7400. Great amp and tuner, really nice aesthetics compared to that Yamaha black box.

I purchased the n100a on amazon for $1,300 usd, new, in black. I have it in my garage with some CSS 1TDX's and a custom 15" sub powered with a Speakerpower HTB-700. Extremely enjoyable! The a/b switching on this amp is really easy to use as I use it with some Overnight Sensations on my workbench. Bass management is great too, via the app. I mostly stream music from Tidal, and around 35-40% volume, the 1TDX's SING. You'd want the n1000a for the HDMI capabilities, which work flawlessly for me.

Amazon.jp lists it, but it is sold by a Third-Party Seller, not by Amazon.jp. Be cautious, as some third parties sell products or color variations not offered by Amazon.jp at inflated prices.

there is always a yamaha in showroom , like kef ... not wiim

this might be dependent on where you live. In Australia, Wiim is sold by many physical audio retailers

It is possible that YPAO raised the right channel by 2 dB to compensate for more reflections (more energy on the left side) due to the proximity of the L speaker to the wall. Lyngdorf Room Perfect also did this in my room due to the asymmetrical layout - I asked support and they said it was OK.

Thanks for the review, @oal. Well done!

As for the device, it seems quite good overall. Those Yamaha receivers always look so pretty with those rectangular knobs

Very detailed review, thank you @oal !

I had one of these years ago and really liked it. I like Yamaha's variable loudness control, but the magic "Bass EQ" button on the NAD always seemed to give me the perfect amount of boost for low-level listening.

About 1200-1300 euro street price here in Europe, an amazing value for a piece of gear with solid performance, credentials, full certifications, schematics and the famous Yamaha service.

Thanks oal!

Thank, nice format with meaningful comments for us lay people.

I prefer the look of the Yamaha, but I do like NAD's too...

Really nice review. I enjoy the N600 that I picked up for $500 in my office despite its budget limitations. MusicCast is a much better service than I imagined. I went from thinking I wouldn't use it to it being my daily driver with my UPnP server on my Mac. Receivers aren't for everyone, but I love the convenience of having all the options I want in a nice looking, reliable unit.

Yes, the DAC is ok for the application, but nothing more. I am surprised the amp holds up so well. This is a lot better than we have seen from historical and recent Yamaha amps and AVRs. The left channel has all harmonics < 100 dB. Was the amp driven through analog in or the internal DAC? If it was the internal DAC, the DAC's distortion was in the same ballpark, so the amp would be even better than it appears.

The right channel has HD3 at -92.8 dB, about 11 dB worse than the right channel, but still okish. Does Yamaha still not believe in bias trim pots? For older amps, there was a fixed resistor, and an allowable bias current range that ranged from way too low to about 10x that number which was still low. I bet the right channel is running at much lower bias than the left channel. You might want to check that. There used to be a resistor you could cut if the bias current was below the lower bound of the tolerances.

Power vs. distortion is beautiful in that it almost doesn't increase with frequency. Much better than most class D amps, and even better than most AB amps with Miller compensation. Did Yamaha finally start using two-pole compensation?

Edit: Yes, same old s...: allowable bias range is 0.45 to 45 mA -- madness! This is from the service manual of the A-S801 that @aol said the analog section was based on.

Weirdly (to my old EE eyes), the top PS rail in this schematic diagram appears to be negative and the bottom one positive, contrary to the convention.

I had one of these years ago and really liked it. I like Yamaha's variable loudness control, but the magic "Bass EQ" button on the NAD always seemed to give me the perfect amount of boost for low-level listening.

on Some of my Yamaha AVRs, they employ a bass boost called "YPAO Volume" and one called "Extra Bass".

The volume one acts like a "mild" loudness contour, and adds a small amount of fullness at lower volumes, very moderate and usable.

The 2nd "Extra Bass" boosts the mid bass region about 5-6 db, maybe the 40-100 hz range about, and sounds great if one wants to add some "Punch" to bass of a smaller speaker etc.

The extra bass, is from memory of NAD stuff, somewhat similar.


I had a Yamaha Pre=amp years ago, that had Variable loudness, and really liked it for the most part. No loudness contour is perfect of course.

Harman Kardon used a Contour that boosted deeper bass more than upper bass, that one was truly helpful at low levels and with smaller speakers back in the day.

Having owned several Yamaha and Technics components I rather agree , I would like to add though that such become an optical disturbance to people who like symmetry as soon as you don't use them in their vertical orientation.

Thank you so much for the review.
Do you have a chance to do some measurements in non-direct mode?
Considering the target audience of this device, this amp would unlikely be used in Direct. Older r-n803 has severe degradation in 'Normal' mode.

The R-N800A is a much more attractive model in terms of price and quality. It differs only in the lack of HDMI ARC and the use of a different power transformer and filter capacitors. It costs $700-$1,100.
