Weren't these guys the old Stereo Exchange in Manhattan? I think it was real estate costs (and emerging and burgeoning technologies) that had them leave New York (don't quote me on this). I went to their opening in Glen Rock, NJ (as someone mentioned, not a cheap location real estate-wise either) and it was just great to be back in a store with all this wonderful equipment (that I can't afford...but that never stopped me from snooping around such establishments 😀 ).
I bought a few used pieces from the Manhattan store way back when (I remember a Counterpoint SA-100 and some other tube amp from Electrocompaniet)...but, alas, never anything new). I had my eye on a few things Sky-Fi has, but it'll be awhile before I can lay out some serious bread and not feel guilty about it.
Hoping (for their sake) that the business as it is, is sustainable and that they're around for a long time to come.
