Does the WATT/Puppy 8 image as well as the 7?

One of the strenghts of the Wilson WATT/Puppy system in its various versions always has been its ability to image with great specifity and precision. With the absence of lead ingots in the most recent version of the WATT/Puppy, the 8, and, correspondingly, less mass, I was wondering whether the company has compromised this wonderful characteristc, despite the change to better materials. Does anyone have experience with both versions that can speak to this concern? Before I buy this expensive rendition, I would welcome opinions. Thanks.
this is a very interesting discussion and one that supports my belief that the watt puppy is the benchmark. it seems to be what every speaker is compared to and many mirror in technical and physical design. wilson simply builds the best speaker in the world. i have 7's and think at the moment, (they are my fave) a steal at the current used prices. 6's too, not a huge difference. there is no more powerful, emotionally and physically, speaker that can match what they do. and once set up, the imaging is like magic. there surely are more accurate, thiel for example which i love, but none as emotional...

just thought i would jump in, i was inspired!
after hearing sonus fabers and eggleston andra's, i personally lost interest in wilson audio's quest to make "the best speakers in the world". one of the absolutely best MADE, no question. but sound-wise, while they are incredibly resolving,
they are perhaps some of the most analytical speakers out there (recall the WP-5's, the X-1's, or the cubs). UNLESS OF COURSE you can fork out whatever a pair of Alexandrias is going for these days. 'cause once you hear THEM you'll "understand" just how crazy-smart d.wilson is. luckily for years now other manufacturer's/designers are on to this marketing scheme and have some of their own amazing SOUNDING speakers to offer (and many for alot less money- like perhaps the new Revel Salons).
Well I just bought the Puppy 8 and have also had the Puppy 5,6,7 and I think the 8 beats the 7 in every aspect. The tweeter is also a little bit less "hot" than the 7 so this is an advantage to me. It is close to the Sasha.
My local Wilson dealer really knows how to set them up and get the best from them. I've heard them from the W/P 6s to the Sashas. Each iteration was an improvement; all had good imaging, but the Sasha was a bigger, more comprehensive leap.

Besides meticulous setup and placement, this dealer has really, really good upstream components--matched sets of D'Agostino, ARC, Ayre, VTL, etc. connected by top line Transparent cable. Wilsons are highly resolving; you gotta feed'em right.

The D'Agostino Momentum monoblocks feeding the Sasha W/Ps was sublime.
I have W/P 7's.  I found violins and sopranos on certain recordings just a bit too brittle.   My speakers are in my rather hard living room.   I've tried two different cables.   One tamed the upper register but also the bass. The other is better across the spectrum but as I've said a little too rough in the upper register.   My solution: place an extra layer of speaker cloth in front of the midrange driver only. Voilá!  Smoother violins with no perceptible added veiling.
