I must really come to Soix's defense also. Not that he needs it. But in this case, he was trying awfully hard to be nice and not offend but sometimes the truth just hurts Brother...and you gotta tell it like it is.
What are trying to accomplish here Mjinz? Per your second post, you " want kind a kind of musical,rich, bright( no cheap brightness that creates fatigue), dynamic." So your going to use a 5K plus amp to drive a pair of speakers that I recently saw at Goodwill for 30 bucks? Good luck, it will never happen.
Soix is absolutely right - if you truly have the kind of coin to buy any of the three amps you mention, look at replacing your speakers first. Then come back and ask us about an amp that will properly drive them. We will be glad to help. You will then be on your way to achieving the kind of sound you describe in your sentence above.
If you are just trolling though, afraid you haven't fooled many and be on your way with your rack speakers.
