Stax recently changed its distributor in the US, and it appears they have not set up a website yet, as far as I can determine. Elusive Disc in Indiana is a Stax dealer, but I don't know what they have for audition. Otherwise, probably the best thing to do is to look for a local or regional Head-Fi meet, where someone may bring an SR009 for audition. As you may know, the majority consensus opinion is that 3rd party amplifiers, in particular the Gilmore amps, sound better than Stax's own amps for driving the 009s, and for auditioning them, a Head-Fi meet is more likely to have such amps than a Stax dealer.
