$15,000 is a BARGAIN for the WPs??? LOL...not in my book.
My perspective is different, though...
I knew Dave when he was in Novato, California and I lived in San Francisco. He sold the WATTS through DB Audio in Berekely, the same establishment that Garth Leerer, now importer and owner of Musical Surroundings, started.
I purchased the WATTS in 1986,and had series, I, II and III with Puppies I and II. In fact, according to Dave, I was the first non-Wilson employee to ever hear the Puppies. I was just lucky: Dave set up my Goldmund Studio turntables for me.
The WATTS at that point were 4400. When the Puppies came out, they were $3300. So, put into perspective, since 1988, the WPs, now the standard-bearer (and I'm thrilled for Dave that he made it!) has more than tripled in price. I know as well as anyone alive, and better than many, what an optimally set up pair of WPs sound like, but they're expensive as heck. That's the part that bothers me.
I've recently purchased a pair of 718s, which haven't arrived yet. If they even sound terrific, I'll be happy. Haven't heard them yet, but that's ok. It didn't break the bank.
So, the WPs are great speakers -- and now they're legendary -- but I could never call them a bargain, given my historical perspective of them.
