I haven't found many dealers who are willing to discuss pricing over the phone and as you've probably guessed Bryston dealers aren't as common as Burger Kings, it takes a bit of driving to get to them.
If you got a good price on 6B SST and wouldn't mind PMing me on how much you paid I would greatly appreciate it. I won't ask for details on when or where you bought it but I'd just like to make sure I'm getting a good price before I buy.
