I can't tell you where to audition these in CA, but I can address your other question, "are the Gallos all they are cracked up to be?"
I've been doing hifi for some time, and owned quite a few speakers, some in the 10k+ range, and when properly setup, the gallos leave little to be desired compared to the other speakers I've had.
For me, they play in the level of the average $8-$10k speaker. IMHO, they have the midrange transparency comparable to Maggies, but with the dynamics and bass control of large dynamic speakers. Their imaging and staging are also some of the best in the industry before you get to megabuck prices. Their highs are also quite unique, and have a visceral quality that I haven't heard in any other speaker.
On the other hand, if you prefer something more warm like a Sonus Faber, you may not like them. They are more in the fast/neutral camp. If you have a live setup, you may need to address the room. If you have bright electronics, the Gallos will not hide this.
If the setup is right, though, I think they are pretty unbeatable for anywhere near the price. I bought a brand new pair a few months back. You might want to snatch a pair up quickly, because they are being discontinued, and the replacement model (3.5) is close to $6k.
FYI, the 3.1s will be upgradeable to the 3.5s.
