wilson sasha daw or B&W 800 d3 or rockport Atria II or dali epicon 8 or sonus faber amati

That MA9000 is a NICE piece!

I have only listened seriously to two of  the speakers you have listed.  The SF Amati Traditions and the B&W 800D3 both driven by McIntosh tube power.  They were at different dealers under different acoustical setting and different McIntosh equipment.

I thought the B&W’s were harsh sounding and too bright for my ears.  I had difficulty listening to them for more than about 20 minutes because of fatigue.  The sound of the SF’s were much more balanced and appealing to my ears.  They had no harshness and were very musical and well balanced with an excellent soundstage.  Also, my wife did not like the appearance of the B&W’s.

I purchased the SF Amati Traditions which are powered by my Gryphon 300.  I could not be happier with the outcome.  The bass is extremely  tight with excellent attack and decay thanks to the Gryphon. The music has an “airy” quality and the speakers almost disappear in my room. They sound wonderful with all types of music at all volume levels.  The soundstage is wide, deep, and high.  I can listen all day without any listener fatigue.

Of course this is my experience.  Since they are all very fine speakers, I would encourage you to listen to all the speakers you have listed to find the speakers that sound best to your ears. I would also encourage home demo’s of the speakers you like best to know how they sound in your environment with your electronics.

For the Sonus Faber Amati Tradition, I actually prefer the Sonus Faber Amati Futura much better.  The newest line isn't always better, and the Futura is more to my tastes.  Just food for thought.  The newest Tradition line, added more treble energy, leaned out the midrange, and are faster and "lighter" compared to the Futura.  It is all a matter of taste, but food for thought.  

Jump on the Rockport Atria 2 ASAP!!!!!!It will sound much better than the others.

I have owned Wilson, B&W, and Sonus Faber and listened to Rockport.  I currently have the Sonus Faber Amati Tradition Homage speakers.  I was not a fan of the B&W sound. I thought Rockport for what you get are overpriced.  I compared the Sonus Faber to the Wilson Alexia and felt there was no comparison.  I am glad I ended up buying the SF's.  My listening experience for the last 16 months has been awesome.  Unfortunately, I sold my house and my two channel system so I am starting over.   I have listened to the Wilson DAW but I did not compare to the Sonus Faber.  I am now looking at the Piega Master Line Source 3 as my next speaker.
