By claiming that the Transrotor arm is easy to adjust, I deprived myself of any excuse that I could have put forward against trying out any other cartridge. Since I want to explore the range of suitable pickups, I will now try a rather exotic system, namely a prototype made by Van den Hul, which carries the designation Colibri-XGW, but differs from the standard Colibri model by the thick, lacquered copper wires that lead from the generator through one side of the wooden L-shaped miniature housing, where they serve as - extremely thin - connection pins. This cartridge is one of the rather light representatives of its kind and requires a tracking force of 1.35 to 1.5 grams. The needle compliance though is not indicated on the hand-lettered wooden box. The Colibri can be perfectly balanced and even the low tracking force can be easily adjusted without having to change the two chromed weight units in the counterweight. I haven't listened to the cartridge for several years, but the sound proves coherent right away. With a tracking force of 1.45 grams and a record with radial offset, the relative movement of the cantilever to the housing is a little too much in my opinion, although this optical impression isn't reflected in the sound. For the Van den Hul, the effective mass of the TRA 9 is at or slightly above the upper limit. Surprisingly, the relative movement decreases significantly as soon as I reduce the tracking force to 1.40 grams. Transrotor's tonearm comes up to show a probable higher flexibility than I would have expected. As to me, teammates such as the Tamino or the ETNA do better match the TRA 9. However, don't be irritated by the fact that the investment required for these ultimate top-class cartridges is almost twice as high as that for the TRA 9: Transrotor's first in-house development does also these full justice!
