The DP-6 |
The top model - an arm with "conventional"
bearings,
a silicone damped high precision ball bearing for the horizontal plane, and two precision
sapphire bearings for the vertical plane. The damping of the two planes of motion is
completely separate, and the vertical can be adjusted to suit. One of the sapphire
bearings is adjustable to ensure correct cartridge azimuth. Silver arm wiring with Teflon
insulation. Finish is 24K gold. |
 The UP-4 |
A Unipivot design, with a hardened steel pivot resting in a
concave polished sapphire. The bearing is damped with silicone fluid. The low position of
the bearing gives greater stability than other unipivots. Finish is
Chrome. |
