I've listened to them at my local Magnolia DC (my nearest BB unfortunately is just a plain BB), and with the $30,000 McIntosh gear ($60,000 total), I thought it sounded pretty good, but nowhere near it's price tag of course; barring the looks, if you asked me how much it should cost, I would probably say $5000 if it didn't have bass, but it did have bass so a bit more (probably not $10,000).I'd argue that auditioning them is best, if not in your own system at least in similar systems and rooms to compare.
Granted, I likely wouldn't say the Salon's are worth their price-tag either, as that's also a lot of money (the cons of being in a niche market).
