WILSON AUDIO.....BIG NAME, BIG PRICE........ARE THEY THAT GOOD?

I have never heard the watt puppy 8. They could be getting a little old. Make sure you check the foam around the tweeter.

The Sophia 3 sounds pretty close to the Sasha to me. The Sophia with its fixed head is more limited in setup. But within that setup (9-12 seating distance) there is less of a difference than one would expect for the price.
You could probably find some old reviews of the Sasha comparing them to the 8s and read between the lines a bit for a glimpse of how the 3 might compare to the 8.

I can get a pair of Watt puppy 8 for 6 grand . Sophia 3's run about 8 grand. Might have to go to sophia 3. I can get Sophia 2 for 6 grand. 

Very good speakers. 
 To rich for me. If you have the coin, FIRST,..I would call and talk about service, repair, reckoning, maybe crossover upgrades, speaker replacement, etc etc.  

 if I’m investing that much on a used pair, keep,your butt covered with info, prices, what,to expect if work is needed.

inspect them before purchase. 

Lets shout about the overpriced Wilsons.

WHAT??? I CAN'T HEAR YOU!!! HUH??? WHA YOU SAY????
