I think the best thing you can do is develop your own level of understanding of what you like to listen to, what you want to hear, independent of reviewers or pundits (like me).
In terms of repair, the boutique gear is often more repairable. How many boutique preamp makers can afford their own custom VLSI chips and firmware? No, the gear will be much more basic, made from components that you can still buy decades from now. This goes for speakers as well as amps and preamps.
