I just got my axiom system a few days ago, and I was over the moon. It included two M80s, the VP 150, two QS8s, an EP600, the A1400, and the Outlaw Audio 990 Preamp. I ran the auto setup once a few days ago, and the system worked beautifully.
Yesterday, I finally got around to wall mounting the surrounds. I ran the auto setup again. This time, things didn't work out so well. The test was normal for the front left and centre speakers, but once it got to the front right, life got interesting. Suddenly, giant sparks shot from the back of the speakers, singeing the binding posts. I was terrified. At first I thought I had blown the whole system!
With the help of Axiom's customer service, I determined that the damage wasn't as extensive as I'd first feared. The speakers were fine (thank goodness!), but I had burnt out the fuses on two of my A1400's eight channels. Axiom was extremely helpful and accomodating, sending me a new A1400 immediately and the postage to return my old one.
The lessons I've taken from this: never, EVER, will I use an auto setup again. I don't think my heart can take the stress. Also, if you're living in Canada, buying from a Canadian manufacturer with as good a customer service record as Axiom is the best way to go. Considering how expensive the shipping and customs' duties were on the Outlaw preamp, I don't even want to imagine how much it would have cost, not to mention the additional time, if this little misadventure had happened with one of their power amps.
