Yeah, the NAD charcoal grey minimalist look (sometimes with odd colored buttons contrasting against that drab grey background) is an aesthetic approach I could never get into. Yes, gear is about the sound, first and foremost, but if we're being honest with ourselves, it needs to be visually appealing. If that weren't important, manufacturers wouldn't have spent so much effort on the visual details. And while tastes certainly vary, the post-late 70's NAD look was never to my liking.
I also dislike the way NAD oversimplified many components. One example is an old NAD CD player I bought cheaply to part out the optical block (as it was a rebadged Toshiba) to repair a old Luxman based on the same Toshiba model. NAD commissioned their version to remove all but the most basic functions (play, pause, stop, skip forward and back, FF and FR) from the front panel, while the Toshiba player it was based on had far greater functionality to begin with (track program ability, different time display modes, etc.). Oddly enough, it had an IR remote, where the original Toshiba unit didn't, and the Luxman I was repairing relied on a system linked remote via a DIN plug on the rear panel.
Now, maybe that was done to meet a price point, but I've noted NAD seems to do that with some frequency. And it wasn't like they were undercutting their competition on price by a wide enough difference that I'd have gone downmarket in features, just to save a few bucks.
