Hi Chashmal, in NYC there are the usual suspects. . . Lyric Audio, Sound by Singer just to name a couple of them. . . they have lots of gear to show. . . but can on occasion be prickly to deal with. Between them you are likely to be able to listen to the top gear from TEAC Esoteric, Audio Aero, EMM, DCS, and a few others. Bring your own CDs. Not sure if they do in-home auditions. By the way, Audiogon has a fabulous long-lived thread for discussing top-flight digital gear where you will find mountains of good info/opinions: try:

The thread is approx a dozen pages long. . . but it's worth reading it from the very top. Guido
