Here's the deal...you're talking to your dealer (with an agenda) about what you should get. Then you're asking our oppinion. So, who are you going to believe?
Do you need to get to the point where all the seeds planted in your head add up,make sense,or you finally listen to the person you like the best?
My suggestion is to try the one you're interested in the most, and if it doesn't work out, sell it, and buy something else! You'll then be like the other million or so audiophiles, who reallize you'll never know anything, till you try it yourself, in your system, in your room/setup, with your tastes!...that's my suggestion. Everyone ownes different gear!!! To each his own.
BTW, I sold a Pioneer receiver about 1 year ago, which is as long as its' been, honesly.
I like the B&K and Denon Flagships sonically over the Pioneer, personally....
