Now that I know you won't embarrass me by wearing white shoes I'll point to a few friends I'd who I'd suggest taking a listen to their offerings. I don't know that all will be there, but here's a few suggestions in no particular order - mostly stuff that might be more challenging to hear at dealers - not positive that all will be there, but if they are, their rooms will most certainly be worth a listen:
Daedalus Speakers
Modwright
AudioMachina Speakers
TAD
Atmasphere/Classic Audio (usually together)
First Sound
AudioKinesis
Art Audio
