Good point! How come they don't make CD/SACDs with the side B on the flipping side?
Because unlike an LP a silver disc can have several layers, and can be read by a laser changing its aperture (laser's wavelength).
Try that with a vinyl!
I love turntables, and seeing them rotating around in circles, but I'm not in love with people still using them for serious listening!
I'm just kidding; the imperfect analogue world is as pleasant as a pheasant deploying its wings.
And some of the best lovers are analogue people (Evange, Rob, Jack, Dave, Matt, John, Doug, Christian, Dev, Mike Lavigne, ...).
