We gave our best turntables the shaft.
And they're better because of it.
The BSR 810 and 710 have their brains in their shaft. A carefully machined metal rod holding eight precision-molded cams. When the cam shaft turns, the cams make things happen. A lock is released, an arm raises and swings, a record drops, a platter starts spinning, the arm is lowered, the arm stops, the arm raises again, it swings back, another record is dropped onto the platter, the arm is lowered again, and so on, for as many hours as you like.
Deluxe turntables from other companies do much the same thing, but they use many more parts-scads of separate swinging arms, gears, plates, and springs-in an arrangement that is not nearly as mechanically elegant, or as quiet or reliable; that produces considerably more vibration, and is much more susceptible to mechanical shock than the BSR sequential cam shaft system.
When you buy a turntable, make sure you get the shaft. The BSR 710 and 810. From the world's largest manufacturer of automatic turntables.
