Aside from buying something from Audiopax, which is based in Rio, Brazil is probably the last place I would buy electronics. My recollection is that the tax on imported electronics is north of 90%, and there is also a significant distributor mark-up and dealer mark-up for the better brands. As an example, Maxx II's in the U.S. retailed for $40,000, while they sold for $100,000 in Brazil. My wife is Brazilian and we lived in Sao Paulo from 2002 to 2005. Before leaving, I sold my Revel Salons for twice what I paid for them in the U.S.
Putting aside price, the market is fairly primitive and most high-end brands available in the U.S. are not sold there - an Audio Research + Wilson or B&W system is considered an elite system in Brazil.
I'm going to alert my audiophile buddies in Brazil about this thread - they have long suffered and will get quite a kick out of it.
