I'm not familiar with the Wilson Benesch ActAudio Visions in SF carries them, and the Von Schweikerts. Both are definitely worth a listen, IMO. As I noted in another thread, the VR4Sr's got progressively better as the dealer moved them from one system to the next, and ultimately into my friend's home. If you go to Audio Visions, make sure you hear the speakers on either the wall opposite the entry to the main room, or on the left side. The right side creates some funky reverberations, and they'll tell you as much.
In case you didn't know, Music Lovers (both in Berkeley and SF) carries Wilson.
If you check on the Tyler website, you will find owners who are willing to audition their speakers. If you can't find a Woodmere owner in the Bay Area, I know there is one here in Sacramento. He's a superb host. I've heard his system twice, and it's also terrific.
Other recommendations:
Silverline La Folia - they are in Walnut Creek, and they are outstanding speakers
Zu Definition - Find a Bay Area owner, or try the 60-day audition.
Joseph Audio Pearl - Superb speakers
Eggleston Works Andra II - What's not to like? They're fantastic.
etc...
Much will depend upon the amp you use, the room you're in, the type of music you like, and most significantly, EVERYTHING that Duke (Audiokinesis) writes above. Anyone can tell you why he/she prefers the speakers they've chosen, but you will never hear the music or the components exactly as they do. Trust your ears. Take your time. Listen to as many of these as you can. That's my advice, anyways.
