@jvandyk: I think I found a set of articles that may interest you (and it is specific to Wilson Audio Alexandria's). It mentions that room acoustic treatment and equalization (WATCH Dog 2) is a much better investment than upgrading cables. It places importance to proper characterization of a room, if you are serious about audio. Really hope you find it useful (I did):

*paragraph 6: "In this arrangement I would be using my subwoofer to reproduce all bass frequencies below 38Hz. I could then employ my Wilson Audio Specialties WATCH Dog 2 subwoofer’s parametric equalizer to notch out the room mode."
Part III: http://www.ultraaudio.com/twbas/twbas_20060215.htm
*paragraph 2: "The Music Vault was simply the most stunning sound-reproduction upgrade I’d ever experienced -- far greater than any single component change I’ve made to my system through the years. This includes the significant move to my current reference loudspeaker, the Wilson Audio Specialties Alexandria X-2, from my previous reference, Wilson’s X-1 Grand SLAMM Series 3."
*paragraph 4: "It is the acoustic output of a system in a real room that is by far the most critical determinant of sound quality,
individual electronic components and cables and their "sonic signatures."
*paragraph 21: "
The way I am using my Wilson Audio WATCH Dog Series 2 subwoofer for active bass-mode cancellation to flatten a low-frequency mode (explained in
of this series) is a prime example of a technique that could be realistically applied only after I’d looked at measurements and acoustical modeling of the room."
Also, regarding Wilson Audio in general, while very good speakers, some of their offerings like the Wilson WATT Series 3, are described as a bit bass lean and bright:
Point being, not such thing as an ideal/perfect speaker AFAIK (including Wilson Audio.)
Ultraaudio..they've been around high end audio for a long time. That long haired guy...forgotten his name.
You know, like I said earlier, my buddies Alexandria system does have a very expensive eq as an option. It was not part of what Wilson recommended when they did the setup. Both he and I think the eq veils the sound a bit when switched in..of course, he could like to use it for crappy recordings now and then. As for Watt puppies, they have sounded different as they've been updated. Version 3 is 6 generations ago. I wouldn't expect any speaker to be perfect..Alexandria's or anything else.
You did link up more subwoofer info, which of course means eq is almost mandatory. Good stuff though.
