KenMasters with all due respect perhaps you should back your statement about 'poorly performing products in the AV space" up with some hard facts.
Historically NAD AVRs have not done well in more mass market orientated hi-fi mags such as What Hi-fi? Question is why, given positive reviews in the USA press etc? Perhaps it lies in that What Circus? giving more weight to bells and whistles, latest tech for A/V Surround Sound purposes, versus stereo performance. Although to their credit I have seen tests on Jap AVRs where they said that stereo performance is below average, compared to other AVRs
And the point you are missing - the gist of this article is about using an AVR in the stereo, hence the stereo performance.
For the buyer it becomes horses for courses. If multi-channel effects and bells and whistles is more important to the end-user, than stereo 2 hi-fi performance, the Jap way should be satisfactory. But then live with the lack of stereo musicality.
Just a few examples of the opposite of "poorly performing products"... with regards to NAD AVRs
14 Aug 2019 — T758V3 - EISA Editors voted to recognise its versatility, value, performance, and future-proof design.
Best Premium Home Theatre Receiver by World’s Most Prestigious Hi-Fi Press
EISA, the Expert Imaging and Sound Association, is an independent body of over 50 speciality electronics magazines from around the world.
Wow, seems to me that in the contributor's esteemed opinion they got it wrong...
Let's have a look at the statement re the Masters M17... and what some of the reviews say.

Conclusion
The NAD M17 is a compelling surround sound processor. In terms of audio quality, this is one of the best processors I have experienced. Build quality is impressive, with an appearance to match. The Modular Design Construction is an amazing promise by NAD to future-proof the product for any unforeseen evolution.

05 Sept 2018 — At $5999, the NAD M17 V2 SURROUND SOUND PREAMP PROCESSOR is expensive, but I defy any preamp to best it for less than twice the price.
Pros and cons: Beautifully layered sound ⋅ Tremendously-wide front sound stage ⋅ Broad dynamic range
USA- Stereophile.com - The one that counts most...
NAD's Masters Series M17 V2 is a superb-sounding pre-pro and DAC right out of the box, but Dirac Live elevates it to something special. Instrumental timbres seemed more realistic, soundstages were nearly holographic, and my listening sessions grew longer from sheer musical enjoyment.
And there is more
Finally a blast from the past - Something in the statement of 'historically NAD' and then further unsubstantiated remarks..
In the early 2000s there were 4 NAD AVRs on the market - the T741, T751, T761 and the T770 - 3/4 was listed by "Hi-fi Choice" then the UK's premium hi-fi publication as "Best Buys".
Much to the absolute annoyance of the Jap brands Hi-fi Choice did a comparison test of 5 5.1AVRs. All were rated at 100W per channel. The purpose of the test was to determine the real world output whilst driving all channels simultaneously. The contenders were models from NAD, Harmon Kardon, Marantz, Sony and one other brand. Only the NAD and the HK met the manufacturer's claimed spec of the 100W output per channel. The others failed dismally. The Marantz delivered only 25W pr channel into all 5 and was specced at 100W per channel
A finally 2 comment - How did the T758 that originated in 2012 win the the EISA award in 2019 as the T758V3? Through NAD's unique MDC upgrade technology, whilst most other AVRs, if not all dating back to 2012 can be found on the proverbial technology-of-yester-years scrap heap.
