Any bad experience with wilson audio sasha w/p?

I have heard them recently at 2 different demos. One shop was hosting Wilson and a cable I don't remember. The second was at different shop which was promoting JL subwoofers.
I was very impressed to put it ,ildly and I tend to be a negativistic skeptic most of the time. The electronics in both cases were high end, SS Ayre and McIntosh. The imaging, as mentioned was astonishing, the detail very fine, and even without the sub they covered all frequencies especially the mid and low bass admirably, Even the Mac which I generally don't love sounded great with these speakers, and the Ayres sounded stupendous even with the old metal tweeters. It will be a very special fabric dome indeed, if it is going to match the current speaker's treble.
As mentioned already these speakers are very expensive and a serious investment for mere mortals. Check them out in persoin -who knows maybe the silk tweeter has negatively impacted the sound.,
There is a good reason that this expensive brand flourishes and isn't letting up in their goal of perfection. I own JM Focals BTW and would have a difficult time if I had to choose between a Utopia and a Wilson.

If you plan to buy a new pair of Sashas, you may want to wait until late Fall. Wilson will be releasing a new speaker just above the Sasha called the Alexia. There may be a few more used Sashas hitting the market by then and they should be in excellent condition. You may not have the benefit of a dealer setting it up for you, but you could save lots of money and still hire a professional to set them up.

I have heard them sound very good at shows, but also very mediocre. Same at a dealership and in a friend's home. I think amplification and cables are very important. The tweeter can be a bit strident, and the bass can be a bit boomy, in other words, not a very coherent and balanced sound, but if they are set up properly, I've heard them sound excellent.

I'll preface my statement with I've been a Wilson Audio fan since the release of the Wilson Sophia 2s. The Sasha's are the best speaker that I've ever owned. They are dynamic, smooth, and chameleon like. Sasha's have an ability to disappear and let music float in air. I submit they can be difficult to set-up and electronics/system integration is crucial. Everyone doesn't prefer the Wilson sound and at this price I encourage you to listen to as many speakers within a given price as you can...Rockport, Magico, and YG are just a couple that come to mind. The bottom line is let your ears decide.

I got good feedbacks, that's why it's worth posting in audiogon. I tried listening to sasha in Hongkong audio show recently but people come and go, so it was hard for me to appreciate the clarity of sasha. Last night, I had the chance to listen to a brand new one in an audio room. It sounds great but a lot of serious things have to be done like proper positioning, right cables and of course the power amp that will match a good speaker. I guess I have to wait for a while until Alexia is out in the market . . . hope I can get a good deal. Thanks for all the info.

It does not look like the Alexia will be a viable alternative to the Sasha unless the price is much cheaper here than in England. The price over there is suppose to be 200,000 pounds; or $300,000 or more depending on conversion rate. May be a great speaker but looks like it will be in a totally different price class, i.e. 10x as much. A friend has the Sasha and they are very good but are very demanding of associated gear.
