best concert venue


What's the best SOUNDING concert venue you've been in? Anywhere in the world. Large or small; famous or obscure?

The best hall I've ever heard is the Concertgebouw in Amsterdam, then the Musikvereinn in Vienna.
In this continent I would say Jordan Hall in Boston for chamber music, and Carnegie Hall is still magical overall.
The Opera House in Sydney, Australia is acoustically outstanding. The views are also fine from anywhere.
