What is "west coast sound"


I recently read a review of a CDP from HiFi Choice which characterized that the player has a "west coast sound".

Anyone knows what it is.

It used to mean: Jefferson Airplane; Doors; Greatful Dead; Quicksilver Messenger service.
Don't know what it means these days.

Is that anything like the West Coast Offense in football?!

Maybe it means the CDP can play short pieces of music like you can't believe. But longer pieces are a bit too much for it.

(Seriously, I have never heard it either, and I live on the west coast. Well, at least the west coast of the USA. Maybe they mean the west coast of England or France?!)
Taking Kurt_tank's analogy a little further... maybe the "West Coast" sound is more finessed, quicker and leaner (brighter, detailed?). As opposed to heavier, powerful, etc. (warmer, laid back?)

Funny, it's also the first time I've heard of this term.
