I'm sure lots go into the price of the Woo amps. The case, the point-to-point-wiring, the people hand making them, the high cost of living in New York, and the fact people will pay it. I mean, it's not like they are outsourcing labor and most parts to another country. Built in the US, so the prices reflect this. In my opinion, my WA3 is worth every penny paid. I'm very happy to support a small business, which is exactly why I also ordered an Asgard.
I would agree that you pay extra for the exterior of a Woo amp, but I think it is worth it. They keep there value better in my opinion. That is why I'm buying another Woo amp.
I have only head good things about WA2 and the Concerto with the T1. I'm sure some people dislike those combinations, but it is usually they like them something else better.
