Hey guys, I am lucky to own one of the cleanest 7070's you have ever seen which was sold to me by a friend that I don't think I'll ever let go of. However, I have thought about getting either a 9090 or a 9090DB in addition to my 7070, but I don't know which one in the 9090 series is "best"? Do they differ at all in sound quality? Are there any reliability problems with either model? What's the general consensus about each one? Most important is overall quality of sound. Do you like one over the other, or are they the same? What say you?
