Hey guys, I've read alot about the earlier hiss problem with the 950, and that there was a fix implemented in the earlier models. I've purchased my 950 about a month ago, and have noticed that when i get to approx. -10db to +10db, i notice a hiss coming from my mains. Is this not supposed to happen ? I would assume that a certain amount of hiss is normal, when the amp and preamp are wide open. Please let me know, what you guys think. Thanks.
