The Wilson approach has certainly won the day
Could be argued their success is partly an artifact of their pricing. Here is Charles Hansen’s take on Fremer (and most of the audio press, by extension; from an audioasylum post):
a) The more expensive the product, the better it must be.
b) Wilson loudspeakers are the best on the planet, presumably because they play really loud, have super spectacular bass thump created by the +10dB bump they all exhibit at 70Hz, and are ungodly expensive (see (a) above).
@tomthiel thanks to you and Jim for bringing a superb level of performance at price points that most can afford!
Again, Charles Hansen from an audioasylum post:
The high-end wouldn't be where it is today without the contributions of Jim Thiel and Richard Vandersteen.
