The entire industry is in a major shift.
We're now in a phase where most boutique amps and vintage replicas are mass produced and widely available in kits.
Major amp companies (i.e. Fender) now make their own vintage replicas and boutique amps.
It's actually pretty exciting.
Well if it's true for wine it must be the same for amps:
I don't really think this concept works or translates to amps as well. Most people picked the more expemsive wines because most people don't know jack about wine, and therefore rely on someone elses suggetsion that it is pricier therefore better. I'm not saying that doesn't happen in the amp world, but come on ... most of us know a LOT about amps and can't be fooled that way. I have bought a few pricey amps and flipped them because well, they were not very good. I have owned some cheapy amps that I liked quite a bit and thought were killers despite there price tags. Just my $0.02. I think I'm trying to say it is relevant to how well educated you are about the subject as to whether you can distiguish the quality of said subject.
