De Mørch-armen komen uit Denemarken.

DP staat voor Dual-pivot, d.w.z. het verticale lager wordt gevormd door twee saffierstaafjes die op hun punt op lagerblokjes in V-vorm rusten.

Mørch pick-up armenModel DP-6

has a unique combination of bearings. A silicone-damped, high precision ball-bearing assembly is used for the horizontal plane of motion. Two precision sapphire bearings are incorporated for the vertical mode of motion, which may be damped also, if desired, by injecting silicone fluid into a well for vertical damping.

The damping of the horizontal plane of motion is independent of the damping of vertical mode of motion, and the latter can further be adjusted to all intermediate levels of damping. In model DP-6 the azimuth adjustment for perfect channel separation is accomplished at the pivot of one of the sapphire bearings.

Model DP-8

Mørch has introduced a new top model: The Mørch DP-8.

On the 4th of July 1981, Hans Henrik Mørch sent out a new tonearm to his auditioners. It was a prototype, a UP-4 modified to have greatly improved deep bass performance.

But at that time audio equipment was not very concerned with the deep bass reproduction of vinyl records – the auditioners did not hear much improvement, and the project was abandoned. Somewhat ironically the introduction of digital audio helped advance the quality of deep bass – for instance, subwoofers are now commonplace.

After 25 years the old prototype was dusted off and eventually became the DP-8. The improvements in deep bass and dynamics are now evident…
For this new model the effective mass for the horizontal mode of motion is many times larger than the effective mass for the vertical mode of motion – no matter the effective mass of the armtube used. This provides for tremendous improvements in bass response and a lot more dynamics.

The DP-8 got the Golden Ear Award in The Absolute Sound June/July issue 2010. In the article, the author refers to the DP-8 as “anisotropic”, which is a short technical way of characterising the new features.

Read more about it on the DP-8 product page, where the anisotropic principle is also explained, and in the reviews.

Model UP-4

incorporates a special concept of the unipivot principle. The bearing consist of a hardened steel pivot resting in a concave, polished sapphire. The bearing is damped in all directions with silicone fluid. The low positioning of the bearing provides for a greater stability compared to other unipivot arms, since a considerable part of the moveable mass of the arm is positioned above the pivot point.

With the model UP-4 the azimuth adjustment is made by the way of the counterweights. Vertical cross section of model UP-4 through pivot and sapphire. Supplied in CHROME- or 24 carat GOLD finish and at speciel orders also in BLACK. The armtube plating being made without the use of magnetic materials.
