"Not sure what the OP has for gear or cables, but by saving some on the A21, I'd suggest getting some good cables, I've purchased from Audio Advisor and they are pretty knowledgeable."
No offense at all, but I really disagree with that statement. Cables make a nice difference, but I would never get lesser active components so I could spend more on cables. Not only that, but if you pick good components and match them well, it makes cable choice a lot easier.
"I listen to contemporary Jazz, and my priorities are soundstaging, imaging(front to back placement), and as close to neutral as possible without brightness."
If that's your main goal (not to say that you don't have others, as well), you need to build a system, not buy an amp. Your source and preamp components are at least as important. They all have to work together.
