I'm confident many folks on this forum have heard the Wilson line and you will get a broad range of opinions regarding their value. And then you have to decipher value versus model.
I think we can all agree that David Wilson is a very acute business person who has created a sales strategy, along with ads and dealerships, that promote the brand quite well.
Having heard numerous models over the years, my sense is that they make a good product but, IMHO, are over priced. However, as with all things audio, value is a very relative, personal judgment.
If you like a particular model and wish to purchase, watch for it on Audiogon. There are many used models available for 30 to 50 cents on the dollar.
