Sorry to hear about your bad experience in NYC, Dinnenjous. Unfortunately like many big urban centers, you run a risk of things like this happening, especially if you're an unwary tourist. It's kind of the NY welcome I hate to hear about from new visitors. There are too many great things happening in Manhattan for you to be able to miss out b/c of one bad experience. If there is ever an audio-related show happening in NYC, I would be happy to act as a guide for you. The annual NY Audio Show that is held ever September is now held in Brooklyn instead of Manhattan, so technically that's not in the city proper, although I bet visiting Brooklyn would probably feel quite similar to visiting Manhattan to you.
