As for the concept of "good enough", it’s an interesting one. No system is good enough for me because it is still far from real. Problem is not only the system but the recordings, most of them. So I just do one or two significant upgrades every few years and don’t think much about it.
Right. I wasn’t suggesting "inherent dissatisfaction" is a problem for everyone.
Nor is the issue of whether a system sounds "real". There are far too many variables involved in live sound to identify a single, baseline for "reality". But if you enjoy chasing this chimera, have at it. Enjoyment is what we're all aiming for, right?
