I read that Cassandra Wilson has B&W speakers.

a friend claims Oprah has Linn speakers that she bought from the Linn store in Chicago many years ago.

I heard some time ago that Wynton Marsalis and his brother Branford both own Linn Sondek LP12s.

OTOH famed conductor Louis Lane openly admitted in front of a group of audiophiles that his system was a $23 child's record player. Correct pitch was all that mattered to him. Everything else was in his head.

Chick Corea was a big Levinson fan years ago while Mark was still with the company. Liner notes from one or more of his albums prove it.

IMO there's no accounting for Herbie Hancock's taste, after hearing him participate in a panel discussion at CES some years ago about surround sound and how he was so much into mixing and processing. Yech.

Wish I didn't have any Linn speakers......they sound great, but now that I know Oprah has them......
