Wilson Watt Puppy, which version?


I am thinking of getting into the WIlson line with the Watt Puppy's. I have heard a few before in showrooms and I enjoyed them. I can not afford a new one, so looking at the previous ones there were several versions produced over the years. Can anyone explain the differences and if there are any "sweet spots" in the line up. ie is every newer version better or was there a point of diminishing return with the introduction of newer versions? I am trying to stay under 10k for a used pair. Thank you

It's also interesting that people that don't like Wilson also aways recommend the Sophia's among the Wilson line-up.

Wilson isn't for everybody, just like Sonus, B&W, panel speakers, etc. . .

People shouldn't buy any of them without not having heard them first - unless of course they are willing to sell them if not satisfied. Speakers are tougher than amps, etc. . . to sell due to their difficult shipping nature.

I think it should be fairly easy to audition past generations. OP should post his general location and seek member invitations. I would be more than happy to accomodate somebody seeking such an invitiation.
I also suggest the Sophia 2 unless Vdosc is considering a different power amp. At one point I owned a VT100Mk2 and WP5.1's. The ARC doesn't have enough juice to drive the WP, the 5's through 8's are a similar load, to their full potential. Yes it will sound good, but you won't get the bass control and slam you'll get with a amp with more beef.

With his amp the Sophia 2 would be a better match.
I have heard and owned both the WP7 and the WP8 and feel the 8 is clearly superior to the 7 in transparency, musicality. In other words, the WP7 is harsh and a bit metallic.

Majority of praises for the WP7 (versus the WP8) are from Wilson dealers and/or Wilson dealer/owners who are/were keen to sell their older and inferior WP7, especially the trade-ins and store demos.

The short life of the WP8 had everything to do with its performance - the improvement over the WP7 was tremendous that Wilson wanted a NEW name rather than the implication of incremental benefits which the "8" version may allude to. In short, the WP8 is closer to the SASHA than the WP7.

Current availability of the WP8 in the 13-15K range (depending upon finish) offers a tremedous opportunity to attain near SASHA sound. Hours and hours of smooth, non-fatiguing musical bliss awaits the purchasers of WP8.
Upgrade1394 - I obviously don't agree with you that the 7 sounds harsh and a bit metallic, as I don't think the 5s sound that way either. But as to the 8 vs. 7 or the 8 vs. the Sasha, I think you may be correct in your assessment that they are closer to the Sasha and may have had a short life for the reasons you indicate. Though I have not listened to either enough to offer my comment - both models are above what I am willing to pay and also above the OPs budget.

As to what the Wilson dealers say, I would be very careful about listening too closely to those comments. For the most part they carry the Wilson marketing and reasoning script. I don't necessarily fault them for this, but just beware it is hard to find a dealer (of any brand) who will tell you that you are better off going out and buying used equipment of a prior generation vs. the current model of the same brand - which they carry.
Upgrade1394---you are mistaken. the short life of the 8 was due to the Magico V3 which was a better speaker at a lower price.
