I posted on the UK forum SoundVideo username. In short, Magnolia (BB) needed to get product into their facility by a deadline or they missed the crucial Christmas rush. So they air freighted some in from Vietnam (the production faculty) to the States. A Magnolia US store might have one.
Here in AZ, a customer of mine (who is head of a very large IT department) and bought a AVR850 from me, was at a local Magnolia. He saw it, touched it, and operated the user interface, listened to etc. In short, it works, no one "had to scrap all of the firmware", etc. Will there be a bug or three? I expect some. Actually, I will be shocked if it doesn't. Just as I expect bugs from every single boutique vendor. After all, I fully predict they are modifying code as we speak. That isn't internal info; rather a pretty solid prediction.
Personally, I ordered up a motherload of the Arcam prepro and receivers. The batch is expected to hit the USA in a couple of weeks. I expect to take in a lot of trades because of Dirac and the price point. The new platform is more flexible, more feature, more channels, I'm told it sounds better, and it costs less than the predecessor. That's a solid formula for selling a lot especially
BECAUSE it has Dirac.
All that said, I'm surprise how a random poster (post count totaling 2) on a UK AV board was able to spook so many people.
