That's the place. It's supposedly an all day affair (10am - 5 pm). Stock is a good question. I have another Paradigm dealer I like to use (never leave all your eggs in one basket). He tells me that there is no stock available until the end of November. If Audio One is selling on that day, this other dealer will be pi55ed!! I was just assuming that when Audio One claims Nov 6 will be the world premiere of the MRX receivers, they'll have stock to sell.
I'll ask my sales guy there if they will actually have stock. I would also advise you to call to make sure they have stock before making the trek.
