I've had mine since 1996 and while they don't sound dated, your question comparing them to the current Wilson speakers isn't apples to apples. If you have the money for the new models I'd go that way. But, I think your real question is do the 5.1's represent good value at $5500?
I have a vast amount of experience with this speaker. I can tell you it is very finicky. But, if you are willing to revolve your system and room around them, they can really sing. It has taken me a long time and much effort to get there, but my 5.1's still stand up to newer speakers and are far better than most.
Your problem, as was mine, will be whether or not your room and other components are compatable with the 5.1's. If they are, you'll be lucky. In the long run it may actually be cheaper to go with the Sophia which I suspect will blend more easily.
Insist on a home demo. Get at least two weeks to try them in your room. It's the only way to be sure. If they work, you can't do better for the money.
