Going to NYC from the outback of Oregon.

HiFi stores are a different animal. You can look at some older posts on the same topic to see for yourself. Stereo Exchange in noho has been around a long time. Most other places are by appt only. I read about some fancy place World of McIntosh that opened recently also by appt only. 

Have fun in NYC

I agree with czar about visiting AudioConnection, Rutan knows his gear and Nick is the vinyl king. There is also AudioDoctor who shows out of his townhouse in Jersey City which would be sort of on the way back from Verona to Manhattan. He has a ton of gear to show just be careful parking make sure you check the signs.
