Gifted Listener, Command and Deja Vu are all great places to stop and listen--very friendly and attentive, no high pressure sales tactics. Of these, Command probably has the widest array of gear.
But, it is Deja Vu that is the utterly unique experience. Much of the gear they have that is really interesting is made in-house or made in Italy by a designer/builder that works exclusively for them. They make gear to order. Of the regular commercial brands of speakers, they probably sell more Audio Note speakers than any other brand, next would be Harbeth and then probably ProAc. There have been quite a few buyers that have come in to audition the "regular" commercial gear that they sell, and after hearing their unique house gear, have gone crazy upgrading to these unique products. The custom speakers are mostly built around vintage drivers and parts (crossovers are built using very old vintage parts), although recently, drivers from G.I.P. Laboratories have been used in their most expensive and exotic designs. Many of their custom speakers are below $20 k.
