BEST AMPS FOR WILSON SASHA

Hi Bo,
The OP wrote "I love Sasha" so clearly he's quite happy with these speakers.  I appreciate that you aren't enamored with them but that's besides the point in this case. He just wants a good amplifier match for them. 
Charles, 

I understand, but the problem is still that it is a difficult speaker.

This is based on the fact that it is difficult to drive, but also difficult to be placed in most rooms.

You have to ask yourself the question: Why you would choose for a speaker with these difficulties. In about 18 years of time I visited several people with Wilson Audio speakers, Often they had difficulties with the acoustics and drive difficulties.

You need to understand that these limitations makes it a lot more difficult to create a stunning level out of the speakers.

At the end the result of the overall sound is what counts most. Many people get a low % out of speakers they own in sound quality.

I seldom audition a set were a person gets a good level in overall sound of the loudspeakers. Many people are not able to create a good balance out of their loudspeakers.

Charles,
I understand what you're saying about the OP loving his Sasha's. However based on my experience with Wilson Audio Sophia 2's, 3's, and Sasha's I sent the OP a PM suggesting that he should consider other speakers. It's just my experience, but I convinced myself that I loved my Sasha's when I had them also. In hindsight I realized I didn't love them and after I sold them I started to listen to music more often and for longer periods. I know the OP and I may have different sonic priorities, but listening to other speakers may help. 

Hi ricred1,
I do understand the point you and Bo are making,  it can be said truthfully that Wilsons aren't suited for everyone  (no speaker is). I'm just accepting that the OP has sorted this out and has determined however the Sasha is the best speaker choice for him. All of this is a pure demonstration of the nature of subjectivity. You became dissatisfied with the Sasha but the OP loves them. 
Charles, 

Bo,
I share your viewpoint in regard to difficult to drive and fussy speaker attributes. Horses for courses as they say.
