The opposite is true as well. There have been builds by DIY guys that rival most famous builders/companies. And fanboys crap all over them because they're "nobody". Then Ceriatone turns around and copies those and puts out a new model from a DIYer's schematic, and suddenly it's an amazing amp because Nik created a production model from a schematic on the web.
What most people fail to realize is... a resistor is a resistor and a capacitor is a capacitor and a length of wire is a length of wire. If Jon Smith solders a 47K resistor to a 0.022uF capacitor, its the same as if [FAMOUS AMP GURU] did it. There's no magic pixie dust transferred.
If more people learned about electronics they'd be utterly shocked and very disappointed by what they'd discover 'under the hood' of their favorite boutique amps... They think they own a Ferrari, but pop the hood and there's a Honda Civic engine looking up at them.
