I’ve received many B&H catalogs ether as hand me downs, and runins with people on the West Coast, or in the mailings these days, but I never made it there till October. I’m familiar with J&R in the Lower Manhattan area though.
Located on the West Side of Manhattan, just a couple blocks away from the Garment District (the off Fifth Ave stores that go from West 34th & 5th to 35th and 8th. I made the visit since it was on the way to the Javits Center, for that fluke of an East Coast NAB Show. This place is a must if you like broadcast grade A/V equipment (the enterprise class for videographers, audio, what have you.) I got studio grade headphones there, and you can buy any professional and commercial class stuff there. And if you can’t make it to New York, you can go online.
