I see what you're gettin' at -- but to look at the price from a different perspective.
Let's compare the "original" NAD integrated amplifiers (all analog, linear P/S, etc.) in terms of
price.
Because I am lazy

I just used the US BLS CPI inflation calculator
backwards to the year 1975 (realizing that the NAD amplifiers that inspired this model came a few years later,
and inflation was rampant in those days*).

As a comparator (from my own hifi shopping history): In 1978, an Onkyo A-5 integrated amplifier (45 wpc) was $270, and the aforementioned Yamaha CA-610II (45 wpc @ 0.05% THD, 20 - 20kHz per "FTC '74") was $290. As my previous post strongly implies

-- I bought one of the latter.

In other words, this NAD doesn't seem
outrageously priced in 2025 CE as assessed by this one, only slightly arbitrary metric.
