BEST AMPS FOR WILSON SASHA

The issue isn't his equipment, it's the constant disparaging of other gear, chest-thumping about his own self-proclaimed prowess in audio, and endless infomercial approach.  The OP wants to know what amplification people would suggest for his speakers, not to be told his speakers suck.

and dartzeel 8550 integrer amplifier is a good option for sasha, can work this speakers ?

Yes, the OP has made it clear that the Sasha is ideal for him  and his choice should be respected.  Bo you make some good observations regarding 2 dimensional vs 3 dimensional sound capabilities of audio equipment.  I suggest that you initiate a separate thread on this topic. 
Charles, 

and dartzeel 8550 integrated amplifier is a good option?, can drive the sasha?

p59teitel,
several people asked for Bo to list his equipment, so I did. I don't agree with his tone either. I think it's funny how so many want to dictate how individuals respond to a post and that's why I sent the OP a PM, essentially saying the same thing as Bo, but in a nicer way. So if based on my experience I submit there are better options than Sasha's, why wouldn't I share my thoughts with the OP? He's not required to take my advice, but it is food for thought. If you read some of my previous post, it's clear that I've owned several Wilson speakers and I got highly offended when individuals, including Bo said something negative about them. Once I sold them and started listening to different speakers, I realized that everyone had an opinion and there was no reason for their opinion to invalidate my own. This is a very subjective hobby and no one, including Bo can create a system that everyone likes.
