I agree as well. I've never owned a brand new amp - never - and I find the history and battle scars alluring. Sometimes the more thrashed the better, because it's so cool to have superior tone coming from an abused relic. Plus, I take my gear on the road, and although I'm careful it does get knocked around a bit. I'd never spend $5k on an amp that'll never leave the practice space - I want others to hear it! Of course, if I had unlimited means, I'd be all over a NOS 2000s. But an extra $1500 just to pretend it's xmas morning 40 years ago and be the lucky sap to open those boxes? Well, I don't know about that...$1500 could buy a lot of previously owned amps.
What we're looking at here is museum-grade amps, which belong with a certain kind of collector. There are guys who spend big bucks restoring old amps to mint condition, and if the final product outweighs the thrill of the project itself, why not drop your money on these and have something really rare - factory fresh perfection.
