I 's pointing out the focus has changed, that's all.
Please note that the only comparison made here was for basic two channel stereo performance. Believe it or not, a few people do still care about basic stereo music reproduction and for them HT is simply an adjunct, much like dessert isn't a main course.
All it's saying is that in the time since then, the focus has changed from a simple product designed purely to provide the best sound to a more complicated, feature-laden product that buried the basic sound producing elements so far down in the hierarchy of priorities that it's almost lost in the noise floor and almost an afterthought.
Let's not even get into tuner performance, shall we?
After all, all that sound "back then" was pretty much all simple, primitive, analog. Today, analog barely exists anymore.
Now, granted, ther ar estill a few two-channel receivers available today but they are far and few between and demand isn't all that great. A comparison between those and this unit might have been interesting though, but the bulk of sales is in the HT area so I guess that's where they chose to focus.
In fact, I'll venture to say that many people today never knew what a plain old stereo is. ...much like people who don't know how to drive a stick shift because they never saw one.
