traveling need audio stores in NYC to audition

You'll be surprised, Audiotomb
There are no descent audio stores in Manhattan. All of them are interested in guys who comes in and asks for building a $50k HT.
Harvey Electronics, Stereo Exchange, Sound By Singer have prices increadibly higher than market retail. These guys wouldn't even speak to you about bellow $5k preamps.
However, if you will contact Dan O'Brasky at Audio Visionary in Brooklyn you might get some usefull recommendations and auditions. He's a showcase dealer at Audiogon.
But the best thing is that there plenty live concerts in best concert halls to audition without home stereo.

If you're willing to drive an hour or take a train north to Mt. Kisco, NY, you can visit Frank Huang and Mike at Audio Outlet and hear at least two of your pieces--Hovland and Audio Research. Plus they are great guys w/some other great stuff to look at and listen to. Whenever I'm in Manhattan I make a point of going to Mt. Kisco. It's near Chappaqua, so maybe you can also see Hill and Bill.

Forget about Manhattan,go to Queens see my pals at Hi-Fi Exchange and Classic Audio.Call Tony or Alex at 718-767-9379.good luck.
