To me, "enough" is when an upgrade is either inaudible or the price/performance ratio is excessive.
For example, I sell loudspeaker kits and some upgrades are both measurable and audible. I distinguish between "audible" and "measurable" because I can measure some stuff that's too tiny to hear. So some upgrades are definitely worth it because they offer an improvement that is noticeable - you can easily hear the difference.
Other upgrades are more subtle. Those offer measurable improvements and yet you can't easily hear the difference. A person might forego that kind of upgrade because the improvement is so subtle.
Some upgrades provide measurable improvements so small that it may be impossible to hear, but yet cost thousands of dollars. The improvement is real - I can measure it - but it is small enough to be inaudible. That's an Nth degree upgrade, one that is only considered in "price no object" systems.
And even some upgrades are just brand names that don't even offer a measurable improvement. Can't hear it, and can't even measure it. So I tell folks those kinds of upgrades are really for "bragging rights." Of course, some people will claim to hear a difference but I think that's an "Emperor's New Clothes" thing. It's another "Nth degree upgrade" that might be worth it to some people but probably not for most.
